Re: [PHP] Algorithm Help
You don't need to maintain the history of which kids stay where unless you
want to for other reasons. You just need to find the children that have
staid the least amount of time together, which this approach would do for
you.
So, when 4 children stay together you say
1 together with 2
1 together with 3
1 together with 4
2 together with 3
2 together with 4
3 together with 4
and that's it. And then you can find the ones that staid together the least
amount of time.

Hi,
Indeed making and maintaining the graph looks like the best approach here
to tackle this problem , but what does not seem clear to me is this --
Suppose a family can host 5 children , then you need to find the set of
5 such nodes out of the total no. of nodes(assume 10) such that the total
weight of all edges connecting the 5*4 nodes is minimum ,
how do you go about finding this set once you have constructed and
maintained this graph and what will be the complexity??

If this has to be catered for you could simply sort them when inserting:
public function together($who, $with) {
$sorted = array($who, $with);
sort($sorted);
$who = $sorted[0];
$with = $sorted[1];

Tom has been with Andrew 0 times.
Tom has been with Shelly 1 time.
Christine has been with Andrew 2 times.

So the Graph maintains who has been with who how often.
For 10 or even 20 kids you might be able to go through all links (brute
force).
The number of links (including the ones with 0 weight) is
#links = n*(n-1)/2
which is the number of links you have to maintain and then check when
you
want to know who should go with whom.
So, if
n=10: #links = 10*9/2 = 45
n=20: #links = 20*19/2 = 190
n=30: #links = 30*29/2 = 435
I think even for reasonably large groups a computer can do the job
easily. I would find it quite hard to do it on paper though, so I
think you
should program it.
You could simply store the graph in an array, and then optionally
persist
it to a db or file:
You would get e.g.:
$graph = array(
'0,1' = 0,
'0,2' = 2,
...
Edit: Actually, maybe you can do it in a two-dimensional array, where
no
node is connected to itself:
$n=4;
function init() {
global $n;
$graph = array();
for ($i = 0; $i $n; ++$i) {
$graph[$i] = array

This means that F1 and F2 are equal in magnitude and opposite in direction., or simplified To every action there is always an equal and opposite reaction.

So, what's good for A could be good for B too but bad for C, and therefore what's good for C is bad for both A and B? Not necessarily (following a implies b is not equivalent to b implies a). It gets complicated very quickly with more parties and we have more than 6 billion! One cannot really say that an action is good or bad for everyone following your argument. However, world peace, less pollution and equal or less diverse wealth would be good for everyone, because of less crime and less risk of loosing everything. Maybe it would trigger something bad at the other end of the universe, but the universe is pretty big (so I've heard :-), so what do we care? I vote for world peace in that sense. Strongly disagree with people saying Someone else would do it if I didn't.. That's just a lame excuse to get rich quick, like I heard from people who sell weapons. Selling ads is not nearly as bad. It's just annoying if they are too intrusive. Google's ads are not so intrusive and look what great things Google does with the money they make in terms of Open Source. I would say Google is the programmers' friend and if anything the lesser evil. Sure they have ads all over, but I haven't yet been annoyed by them as much as other popup ads. Besides that I wouldn't be where I am today without Google (I'm not employed by them in case you're wondering).

Hey,
So i had my first Hackathon at work last week and my project was to
prototype making a node.js clone using PHP instead of V8. So i
snatched up libuv and joyent's HTTP parser and set off on a 24 hour
coding spree to get something workable. By the time the sun was coming
out the next morning the following code was working.
?php
$http = new node_http();
$http-listen(8080, function($request, $response) {
$response-end(yay, super awesome response);
});
nodephp_run();
?
The C code that powers it was whipped together really fast and is kind
of hackish as a result. The code has some memory leaks that i haven't
had time to fully track down yet. Some small portions of the code were
borrowed from the phode project.
In a naive benchmark on this simple server VS an equally simple server
in node.js this implementation already out performs node.js in
throughput by being able to serve just under 200% the amount of
requests per second that node.js could. Take that with a grain of salt
though because node.js has much more feature and is much more hardend
from production use. I do believe the PHP binary will have some major
performance gains over V8 as crossing the PHP -- C barrier seems to
be a much lighter operation then crossing the V8 -- C++ barrier.
Any help or feedback will be greatly appreciated. The projects source

Hi Daniel, You should be able to. Haven't tried it with that specific version, but generally PHP is designed to run with any version of Apache.

Re: [PHP] POLL: To add the final ? or not...
I would leave this to personal preference, whether there is a closing ? or not wouldn't bother me. I could argue both ways: Pro: You should put a final ? for neatness and XML compatibility. Con: It makes the script fractionally slower because 2 more characters have to be processed and there might be issues with the header when it's already sent. I've had that problem before and it's really annoying. Regards, Tim ++Tim Hinnerk Heuer++ http://www.ihostnz.com 2010/1/9 Mattias Thorslund matt...@thorslund.us Hadn't paid much attention to the issue until reading a previous discussion on the topic, here on this list. After that, I decided to be consistent and leave the closing ? out in all include files. To my eyes, ? means look there is more content coming, which seems kind of silly when there isn't. A neat thing with pairing every ?php with a ? when mixed in HTML is that these are valid XML processing instructions. If your HTML satisfies XML well-formedness, your PHP document will also be valid XML. Not that I've ever had any need to process my layout templates as XML but anyway. Cheers, Mattias Daevid Vincent wrote: I'm having a debate with a co-worker about adding the final ? on a PHP page... To be honest, I am the lead, and I could pull rank and be done with the discussion, however I don't like to be that way. I would rather do the right thing. If my way of thinking is old-school (I've been coding since PHP/FI), and what he says is the newfangled proper PHP/Zend way, then I'd rather adopt that, despite how icky it makes me feel to leave an unclosed ?php just dangling and alone, all sad-like. In my mind, nobody gets left behind! :) Is there ANY side-effects to leaving the end ? off? Is it any more work for the compiler? And yes I know computers are hella-fast and all that, but I come from the gaming industry where squeeking out an extra FPS matters, and shaving off 0.01s per row of data in a table matters if you have more than 100 rows. A 1 second wait IS noticeable and a 10 second is even moreso -- just try to talk for 10 seconds straight without a pause. Or sit there and stare at a screen for 10 seconds! If the main argument is that it's to prevent white-space after the code, then most modern editors that I'm aware of will automatically trim white-space (or have a setting to do so). Plus this is ONLY a factor when you're trying to output a header and things like that. In 90% of your code, you don't deal with that. It's also obvious enough when you have an extra character/space because PHP pukes on the screen and TELLS you something about blah blah sent before header output or something to that effect. What do you guys all do? I also created a poll here http://www.rapidpoll.net/arc1opy -Original Message- From: Co-worker To: Daevid Vincent Actually, Zend states that you should omit the final ? on include pages. There is no harm in the action, and it prevents you from accidentally adding white space after the tag which will break the code. http://framework.zend.com/manual/en/coding-standard.php-file-formatting.htm l -Original Message- From: Daevid Vincent To: Co-worker Please DO include the final ? I noticed on several of your files that you have purposely omitted it. Yes, I know the files work without them, but it makes things easier to see the pairings for matching ?php . Plus it keeps things consistent and I'm not a big fan of special cases as this is, especially if it's a bad habit to get into since in all other cases it's required except this one lazy one. If you are concerned about white space sending in a header or something, well then just make sure there isn't any. I've had no problems and it makes you a more careful coder.

[PHP] PHP/SWFUpload progress
Hi all, Wishing you a merry xmas! As a gift to you a little thing that I figured out through long googling and trial and error: We are using the swfupload (flash) upload tool to upload files to a php script. For a rather cryptic reason on some clients the progress would show too quickly when AVG Link scanning was activated on a windows machine. The upload would have completed, but it was actually still uploading. Sound weird? Yes that's what we thought. We ended up solving it by installing SSL (https) on that machine which solved the problem because the anti virus cannot see the upload requests and tamper with it. I know this is not strictly PHP related, but since this list was always helpful for me i thought i would share this for xmas. There is a question that came up though: When uploading to a php page i could find a temporary file that was growing on the server. Couldn't one monitor the growth of that file and therefore track the progress with AJAX poll requests? I know this is more overhead but this seems more reliable to me when there is something funny going on on the client machine, like with the above anti virus. I couldn't figure out how to determine which temp file it was though, because the request would be still going while the file is uploaded and you cannot read the $_FILES variable or similar.

Re: [PHP] uniqid() and repetition of numbers generated
2009/11/14 tedd tedd.sperl...@gmail.com A Interesting thought. My idea on this is to use the approach used when replicating a DB. It is similar to the namespace idea if not the same: Say you have 3 databases, you could use mod 3 numbers for A=0, B=1 and C=2 So on A you would have 0, 3, 6, 9, ... on B 1, 4, 7, 10, ... and on C 2, 5, 8, 11. This way you can just use auto increment and set the increment value 3 and the start value to 0,1,2 respectively.

Re: [PHP] Searching on AlphaNumeric Content Only
Hi,
It's definitely possible to do when you do it in PHP, but not sure about on
the database side. You could read all records into memory and then iterate
over it with something like:
$toSearch = 4D24487PS
$charsToIgnore = array('-','+',...);
foreach ($items as $k=$item) {
$itemVal = str_replace($charsToIgnore, '', $item);
if (strcmp(str_replace($charsToIgnore, '', $toSearch), $itemVal) == 0) {
$return = $item;
break;
}
}
This however might use a lot of memory, but if your DB is a manageable size
it should be ok. You can probably optimise it by iterating over a db result
set instead of reading everything into an array.
Cheers,
Tim

The more I get into arrays, the less I understand.
I have a ridiculously simple task which excapes me completely.
I need to ouput all fields in 1 column from 1 table in two phases sorted
alphabetically.
So, I have the query, I have the results. But since I need to split the
list into 2 parts, I need indexes. I cannot use the table index as it
does not correspond to the alphabetical order of the data column. In
order to get the index, I sort the resulting array and that now gives me
34 arrays each containing an array of my results. Wonderful!
But how do I now extract the arrays from the array?
Here is what I'm trying to do:
$SQL = SELECT category
FROM categories
ORDER BY category ASC
;
$category = array();
if ( ( $results = mysql_query($SQL, $db) ) !== false ) {
while ( $row = mysql_fetch_assoc($results) ) {
$category[$row['category']] = $row;
}
sort($category);
//var_dump($category);
echo table ;
$count = mysql_num_rows($results);
$lastIndex = $count/2 -1; echo $lastIndex;
$ii = 0;
$cat = '';
//print_r($category['0']['category']);
foreach($category as $index = $value) {
$ii++;
if ($ii != $lastIndex) {
$cat .= $value, ;
}
else {
$cat .= $valuebr /;
}
$catn = preg_replace(/[^a-zA-Z0-9]/, , $cat);
//echo pre$category/pre;
echo tr
tda href='../categories/, $catn, .php', $cat, /a
/td
/tr ;
}
}
echo /table;
What should I be using in the foreach line?
Please help!

[PHP] headers: setting right for browser to force reload at a certain point in time
Hi All, We have an application that generates dynamic ebooks. One of the (minor) problems (but yet annoying) is that when a user comes back to an ebook, they have to actually delete the cache and reload the page to not get the cached version which might be wrong because the content or even the flash application is updated. It would be neat if we could force a reload of the page, but only with a special condition like the ebook being updated or the swf. The swf and also the other resources are not reloaded though, because it is a get request. Is there a way to force a reload of the browser by maybe changing the headers? Or do we have to do some fancy stuff like storing a cookie with the time and sending it back via ajax or something like that? Just setting the header would be nice... Maybe the easiest would be to change the link (add a number or something) of the html page and have a rewrite for all the relative urls as well.

[PHP] XML - XSLT transformation using XSLTProcessor class
Hi All, We are trying to import some xml data into the database.

But i need to get the current element name with x-path. So i have the following: rootEl elementAchildOfAsome data 1/childOfA/elementA elementBchildOfBsome data 2/childOfB/elementB elementBchildOfBsome data 3/childOfB/elementB elementAchildOfAsome data 4/childOfA/elementA elementAchildOfAsome data 5/childOfA/elementA /rootEl xsl:for-each select=//elementA | //elementB // xsl:value-of select=childOfA / WORKS and gives the value of childOfA (e.g. some data 1) //... the php code... /xsl:for-each In the php code, I need to get the element tag name of the current element, so either elementA or elementB.

Re: [PHP] Accessors
It's not a bad idea but usually having accessor and mutator methods are used
to validate the data first before writing it to the properties. If you don't
have validation, you might as well set them directly and make them public
and don't really need a generic setter/getter method.
Although, this way, if you decide later on to add a specific getter/setter
for validation you wont need to change the code that accesses the
properties. So, this is a valid approach to save some time.
i believe php should have something like that built in...
In fact actionscript (flash) has quite a clever way of doing this:
With
public class A {
public function A(){}
protected var _b:String = ;
set function b(val:String):void {
if (val.match(/([0-9])*/)) {
_b = val;
}
}
get function b():int {
return int(_b);
}
// ...
}
you can write accessors and mutators which are pretty smart.
With
var instance:A = new A();
instance.b = 1234;
you will call the set method and let it validate a string to be a number
only string, so _b can only be set to a string with only numbers.
I found that very neat in actionscript because instead of writing
instance.setB(1234);
you simply write
instance.b = 1234;
and yet you get the benefit of validation. Then it is safe in the getter
method to return an integer (assuming the validation is right).
Java (and a lot of other languages) seems a bit clumsy in that way to be
honest although i like the language as such. A lot of frameworks and class
diagram code generators generate the getter and setter methods for you, but
if you look at the actionscript way, you see it's not really necessary. It
just adds overhead.
But actionscript just makes it short and you can safely make your members
public until you provide a set method and then you wont have to change any
of the code where you are setting (or getting) it, because it stays the
same!
Actionscript 3 has some very nice features like you can loosely type like in
PHP but you can also give strict types like in Java, making it more flexible
while still restrictive if necessary for stability.
Maybe the PHP developers should think about giving optional return types
with :String for example and get and set methods as in actionscript. ... I
know PHP is not actionscript. But a famous German man who was criticised for
changing his mind said: Why should i keep to my old statement if my
knowlege about the matter has improved? (or similar..., sorry don't
remember who).
Optional return types wouldn't hurt performance wise would they? And also
they wouldn't even change the current syntax! In fact, isn't everything
strictly typed under the hood anyway?
As far as i know, in php you can already strictly type function parameters
as in:
public function asd(string $mystr) {
$this-hola = $mystr;
}
Why not make it complete? Or is it?
Sorry for stealing the thread. ;-)
Also, i know php is an interpreted language. But wouldn't it be possible to
write a virtual machine for php and compile byte code... I know, php is not
Java or Actionscript :-P but it could be an add on feature. i guess the eval
wouldn't work then would it? Although eval could still be interpreted...
This would be nice in case you need to protect your intellectual property.

Hi all.
Maybe I'm wanting more Java-like functionality out of PHP, but I don't
really like getting and setting members directly (even for public members) -
I'd rather use accessors. This way you can control what is getting set and
what is returning. However, I also don't really want to create a million
get/set accessor methods - this is no fun and takes up a lot of space. After
reading around a little bit, it got me thinking about overloading in PHP
(which I'm sure we all know is completely different than any other
language... but that's another day). I didn't want to use the standard __get
and __set methods because that still leaves me with the same notation for
getting/setting members. So, instead, I used a close relative of __get and
__set. Meet brother __call. Could it really be this trivial to get the
notation I'm wanting? Yes. Yes it is. Ok, enough talking... onto the code.
?php
class Person
{
public $age;
private $first, $middle, $last;
// Gotta have our construct
public function __construct () {}
// Here's the fun
public function __call ($member, $args)
{
// Since I know members I want, force the user to only
// access the ones I've created
if (property_exists ('Person', $member)) {
// If args is empty, I must be returning the value
if (empty ($args)) {
list ($value) = $this-$member;
return $value;
}
// Oh, args is not empty! Set the value
$this-$member =
[PHP] shell_exec - asynchronous would be cool!
Hi all, A while ago, i had a problem with shell_exec: I was writing some code to execute imagemagick to convert a bunch of images. This could take ages to execute and the page therefore ages to load. The solution was to get a linux box and append a at the end to do it in the background or make a ajax call to a page that does it in batches. The problem was really that i had to write a file that is then checked against to know when it was finished... Not very pretty. Anyway, would it be possible to make a new shell_exec_async function in php that just starts the process, puts it to the background and calls a callback function or another script with parameters when it finishes? I guess a callback function is not really going to work because the page needs to finish execution. It should be possible with PHP forking though. Anyway, just an idea. Regards, Tim Tim-Hinnerk Heuer http://www.ihostnz.com Emo Philips - I was the kid next door's imaginary friend.
Re: [PHP] shell_exec - asynchronous would be cool!
Yes, believe it or not, when i was writing this, i thought about a db soln
as well. Just hadnt done it that way back then.
I guess with Linux one could do something like:
shell_exec('{longexecutingprogram -with -params; mysql -uuser -ppass
database query; } ');
Surely it should be possible in windows as well somehow. Does anyone know
how (easily)? I mean i could write a win32 executable that could do it but
that might be overkill.
But still you have to continuously check the database if the value is the
expected which seems kind of unelegant.
Or, you could call a php script at the end like so:
shell_exec('{longexecutingprogram -with -params; php myscript.php with
params; } ');
In myscript.php you could have something like:
?php
// send request back to user whos ip and headers would have to be saved and
sent.
?
Would this work? Maybe one could write a library for that directly in php...
So you could actually have a exec_async function without having to write a
php module or something like that. I would be interested in writing a php
module at some point anyway though. I know c(++), so it should be doable.
Is it possible to retrieve the session variables of a user in php cli?

What about calling a shell script with the exec call, and as the last
instruction (or continually throughout its execution) it can update a
database entry. Your PHP code can then look to see if said entry either
exists or is in the right state. It should be faster and prettier than
writing a file.

But alas, that has nothing to do with php, so I apologize to the list. Anyway, back on topic - if you want to encrypt login, use SSL. You can self sign for free. If you don't want the FireFox 3 issue, there are a few free and plenty of cheap certificate authorties that FireFox recognizes. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Re: Sorting times (SOLVED before tedds crappy SOLVED)
Remember we have copy-on-write in PHP.

function timeStamps($ar) {
$stamps = array();
foreach ($ar as $timeString) {
$stamps[strtotime($timeString)] = $timeString;

}
function sortTime($ar) {
$timeStampAr = timeStamps($ar);
ksort($timeStampAr); // since the keys are integers, timestamps ksort
would do the right thing
$ar = array_values($timeStampAr);
return $ar; //dont really need this but just in case someone prefers to
use
//it differently or needs a copy

sortTime($timeArray);
/* this way the strtotime function is only applied once to each time string
which is probably the most expensive. And ksort uses the sort algorithm that
the PHP core programmers regard as the most efficient. I believe quick sort.

Well, I just thought, since the strtotime() uses the current timestamp
to calculate the new timestamp, if you only give it a time then the
returned timestamp is today's date with the new time you passed. If you
had a large array and the callback started at 23:59:59 then you could
end up with some times from the date it started and some from the next
day, which of course would not be sorted correctly with respect to times
only. So, this might be better (not tested):
ditto (as in nice syntax error).
function time_sort($a, $b)
{

Your best bet above.
and G.W.Bush is a socialist.
I did a little test, the ultra-fast version offered by McKenzie
is really great as long as your array of time strings aren't ever
going to be longer than say 3-4 items (with the caveat that you
don't use a second argument to strtotime() ... if you do then
even with 3 items it's substantially slower).
for any reasonable number of items my tests show tedd's version
pisses on McKenzies from a great height (note that I actually
optimized Mckenzies variant by halfing the number of calls to
strtotime()).
I added a third variant, as a sort of control, which runs pretty
much on par with tedd's version but uses rather less LOC
(tedd you might like it as a little example of using array_multisort(),
i.e. a way of avoiding writing the double foreach loop in this case)

yes there are situations like that but then it could just submit the form (which would happen anyway) and check the plaintext password like normally if the other mechanism fails. If people have js turned on it would simply increase security a little. The crucial part is just the sending of the password.

Re: [PHP] Re: for the security minded web developer - secure way to login?
well httpus seems like a good idea though. Thats the kind of response i was hoping for. :-) Maybe browsers would implement that idea in the future. I like that idea a lot actually. I mean when you login to your linux server the first time with openssh, you also have to accept the certificate. In the end you have to trust something somewhere anyway, even if it's just the programmers of the browser and other software... I mean who seriously looks through all the source code of the linux kernel even though it is open source? And even if someone does it (good on them), do they understand every single line? A back door could be just a few lines of hard to understand code, that you might skip. It could even be encrypted and assembly making it very hard to decipher. Who has that much time and brains? With windows you have to trust M$ even more because you cannot even look, and i seriously doubt anyone can disassemble the whole windows OS and read the code. They would not finish in this life time, not even through 50MB of source code i believe. That's a lot! A warning at the top of the page like as if there were blocked content would be sufficient until the user clicks to confirm the validity of of the cert. The warning could just stay until clicked or don't show me again or something like that. FF3 atm changes the whole page when a cert is not authenticated. httpus could have a small warning but leave the site in shape and let it work. This would also have to be implemented in web servers though, but why not? Seems like a brilliant idea to me. The warning could also only be displayed once. I mean you only get warned once that every form gets sent over an unsecured network anyway. I bet even you security contious have typed in something somewhere that you maybe shouldn't have :P. I certainly have... Anyway, good idea, suggest it to the Apache and FF developers and M$ might follow at some stage if they believe they can make $$ with it or they would loose some if they didn't :). Sorry, this is really loosing its (direct) context to PHP. But maybe you could even do a layer higher than the protocol and make a PHP module or something that encrypts requests in some way without the programmer having to be aware of it. Altho i cant think of any way right now since the browser does the request. Or maybe it could insert smartly a javascript and attach an event listener to all forms... How about a js library that even encrypts? One could use RSA or Diffie Hellman or similar for key exchange, all in js and php and store the session key in a cookie, just like the session id... Maybe js is a bit slow for those kind of calculations though.

I might end up just paying godaddy - I think they charge $12.00 / year, but since I already register through them, they already have my address etc. Yeah the cheap CA's are IMO actually a problem. I (personally) think we should have a new system for this scenario: http:// = totally insecure https:// = secure and to a reasonable degree of trust (e.g. no $12.00 certs!) httpus:// = secure but no aspect of trust. httpus:// would support SSL in exactly the same way as https but the UA would simply not display the URL any differently to a standard http connection. This would give responsible developers the ability to provide SSL services where they only really care about the pipe and not the trust aspect. The problem with the cheap certs is that people do not see much difference to the expensive ones and this leads to the possibility of being hijacked. The weakest link is always the end user not knowing any better. The High Validation certs used by big companies at least show up differently in FF now but if you were to replace it with a hijacked non HV cert, there is still a good chance most users would still use it.

Hi All again, What makes it so expensive to have a certificate? I mean, wouldn't it be possible to setup a new authority that doesn't charge as much or nothing at all? Wouldn't the major browsers be willing to support an authority that is free or costs next to nothing?

I have a v-server on the Internet and wouldn't mind setting it up as a free authority or even one based on donations. Or is there going to be so much traffic and processing that it wouldn't be able to handle it? Cannot be that bad because it needs to compute the authentication only periodically (once a year or so for each) and each time a user hits a page it is only checked which would only be a couple of bytes traffic (per domain?).

[PHP] for the security minded web developer - secure way to login?
Hi All, A few months ago it came to my mind, that it might be possible to make non-https session (reasonably) secure by at least not letting people login that shouldn't because they might have sniffed the password from a user. Please let me know if you can find a loop hole in this process. I think it would be interesting for anybody on this list (or anybody really) who has a bit of knowlege and appreciation about security: Assumptions: The session variables are stored on the web server and not transferred to the client at all. The client has Javascript enabled. We have a secure hash function, say sha1. We can generate truly random numbers/strings with PHP which cannot be guessed call it salt. A session cannot be stolen. ... add more if needed. :-) So, we could on the server generate a random salt value and send that to the client along with the login form. On the client, when the user submits the form, we take the entered password value (with Javascript), hash it with our sha1 function, concatenate it with the salt and compute the hash value of the password together with the salt (again). All this in Javascript or whatever runs on the client. We then send this hash value, call it h(h(p) + s) (hash(hash(password) + salt)), to the server. Its useless for the sniffer, because the same value will never be sent twice, unless of course the user (password) and the salt are the same (or there is a collision, but we assumed its a secure hash function). We could make sure that a user doesn't get sent the same salt twice by storing them in the database when used and checking against them when it is generated. On the server we could do the same process with the stored hash of the password (assuming the hash of the password is stored), otherwise it becomes necessary to also send the actual salt of the password along with the login form and this would become even a little more complex. So, if h(p) is stored, we would simply compute h(h(p) + s) where s is the salt that was sent and stored in a session variable. Assuming we don't use a salt to store the password hash, this seems quite secure to me, don't you think? I mean, of course someone can still steel the session but it becomes a lot harder to figure out the password by sniffing. What do you think? If everybody agrees this is worth implementing, i might give it a go and make a library. Sorry this is not directly PHP related, but since i like this list, i thought i would share it with you.

I have secured the login form for my CMS with a challenge-response thing
that encrypts both username and password with the

The principles i'm about to explain stay the same.
*but i'd really like to know if my crypto can be improved*
So instead of the browser getting just a text-field for username and

Re: [PHP] Execute EXE with variables
Hi,
I've had a lot of problems with shell_exec too. Mostly it was permissions or
environment variables not being set. i dont know if there is a way to set
environment variables in the php.ini but if not you can set them with
shell_exec as well, at least on unix it works. You can simply concatenate
the commands necessary with a colon (;) inbetween. Maybe you can have
multiple shell_exec commands and it stays in the same env. Not sure about
this though. Please someone enlighten us on this...
Hope some of this helped.

Re: [PHP] for the security minded web developer - secure way to login?
Hi gang, Was just thinking of a cheap solution for sites that don't require absolute security. A SSL cert cost about $150 a year. Sites like facebook could use this... Of course it's not for banks etc. You could degrade gracefully when javascript is turned off to just sending the form and checking the password normally if the first test fails which would happen anyway wouldnt it? ... Mainly this was just ment to be a proof of concept. An alternative to SSL for those who have more time than $$ and not quite so high a security requirement. Of course SSL is better! Duh! Just wanted to give you guys something to think about. The password would not be given away like this would it? It just makes it a little more difficult for script kiddies.

Re: [PHP] PHP OOP
A loosely typed language like PHP might not be the best choice for teaching OOP, because even though PHP makes it easier with loose types, you should know about them and how they are stored etc. PHP is a great language but maybe not strict enough for students to understand all the errors that can occur. I would recommend encouraging learning PHP though as it has become both an important and fast and easy language to program in. For that it's also amazingly fast in execution.

[PHP] (Perl) Regular Expressions - oposite match or get the non-matches of a substring
Hi all,
I consider myself quite good with Regular Expression, but i could never find
out how to match something like:
match this but not this and that
so i would like to match the first match this (or another this) but not
not this.
Seems pretty straight forward but i haven't found a (good) solution yet.
Please no solutions with extra code, i know how to do that. I need a regular
expression that can do it, preferably Perl compatible. Surprisingly i
couldn't figure out how to say '/!(not) this/'. Seems like there must be a
simple way, but i can't seem to figure it out.
Tried things like: '/[^n][^o][^t] this/', '/[^not]{3} this/' etc but all of
those don't work. Looked in various books and websites but didn't find what
i was looking for...
Please enlighten me if you can.

I'm just getting into programming in an Object Oriented fashion, and

I only just found out that you remove the $ from variables when
calling
them from $this-
e.g :

class People

private $person = not set;
function __construct()
{
*$person* = A person; //This doesn't work (well it creates a
variable $person that only has the scope of the current function from
what I can gather)..
$this-*person* = A person; //This works properly
}
function display_list()
{
echo $person; //This doesn't work
echo $this-person; //This works.
}
}
$person= new People;
$person-display_list();
?
Instead of painstakingly working out most of the other mistakes I'm
likely to make, I'd love to read about other peoples issues they had
with learning OO so I can skip most of the hard stuff, and only make
small mistakes (hopefully).

Hi,
I'm having problem with function move_uploaded_file() under Linux
(Slackware 12.2). It simply won't execute only that function in php
file. So maybe I should add something to http.config file or ? I
tried to execute that php file under Windows and it's working just
fine (I've copied whole project to xampp's htdocs folder and run it
normally).
Can you show some code?
This is part where I use function move_uploaded_file()
if($_FILES['file']['name'] $_FILES['file']['size']55){
$file_name =
news_.$_FILES['file']['name'];
$image=../_img/news/.$file_name;
//Upload file
move_uploaded_file($_FILES['file']['tmp_name'], $image);
}
And normaly HTML code:
Make sure that the relative path resolves to what you think it does. Try to
make a test with a hard coded absolute path, and do an echo
realpath(../_img/news/$file_name); to see the absolute path that it
resolves to. It might be that the function does indeed work, but places
files in annother folder than you expect it to.
form action=?php $_SERVER['PHP_SELF']; ? method=post
enctype=multipart/form-data name=form id=form
...
pbr
Slika [max 500kB; formati: gif, jpg, jpeg]:
input name=file type=file size=50
/p
.
And also I have question, does anyone knows how to configure apache
(also under same Linux) so that in future I woul
dn't have to write
?php but only ? every time I start php code?
You need to change the enable_short_tags directive. It is probably
more
simple to do it in the php.ini configuration file and not in the apache
configuration file, but you should know that short tags are off by
default
because they conflict with xml.

Re: [PHP] Session variables
The session data is stored on the server. In the user's browser, only a session cookie is stored, usually a random session id string. I could never retrieve the session variables with any browser tools, always only with PHP by echoing them out or something. Also, a cookie is simply a text file with a maximum of 4096 characters on the user's browser, not enough to store big session variables with big objects. So, the user's browser just stores a cookie with the session id, so that the server knows which user to map to which session variables. The session variables (in PHP) are stored in the temporary directory on the server in a text file (flattened or serialized), where the server can retrieve them across requests. This is important for security reasons. You might not want the user to be able to view certain variables in their browser otherwise they could change them and cause some damage, e.g. imagine a user has a permission level between 1 and 10 and 1 is the super user. You can store this level in a session variable, and the user cannot change it. If they could, it would be a disaster! Also, if one could store more than 4096 characters, it would be relatively easy to write out some session variables in order to flood the browser memory and make it crash or even worse. Oh, and the Cookies, as far as i know, are always sent in the http headers. They are stored on both client and server and can be set on both sides, with javascript or server side code (php). So they can only be checked in every request by the server side code, and while javascript is being executed on the client. Please correct me if I'm wrong because I would need to review a lot of code in which it is assumed that session variables are NOT stored on the user's machine. Makes sense?

Re: [PHP] Sometime the code works and sometimes doesn't
I would also suggest that you hash the passwords at least (better even with
a salt value) and then reset the password to something random before sending
it to the user. Email can be sniffed relatively easily and this would expose
a possible carefully chosen password by the user and then they have to think
of something new which they probably forget (although, they probably forgot
the password in the first case :-).
Maybe there is a possibility that you have 2 or more user records with the
same email address? because then the result count would not be 1.

Re: [PHP] function_exists question
Why can't you update to Version 5? I might be a bit anal about trying to
always get the newest version of everything, but seriously version 3 has
surely more known security issues as well as performance costs.
What's the cost of upgrading compared to the cost of writing code that works
in every version? I think upgrading the system to PHP 5 will take you maybe
half an hour, while you can spend a lot more hours on writing backward
compatible code. PHP is not very good with compatibility across versions
anyway. Hopefully all PHP 5 code will work in PHP 6.
How about this PHP developers: You could make a global variable (or
constant) the user can set like
define('PHP_COMPATIBLE_VERSION', '5.0.1');
or something to tell PHP 6 to interpret it like PHP 5.x . That way, at least
you are guaranteed that the code will work like on that version. It might
make PHP 6 (a lot?) bigger but it might be worth the cost, since all Sites
written in PHP will still work. The functions could still have a performance
boost that way if there are better algorithms.
Sorry for steeling the thread.

Is there a way to check not only if a function exists, but also to check

The reason being that additional options have been added in php 4 and 5 to
various standard function calls, but I'm still running a php3 and php4
server in addition to a php5 server. I would like to make sure that certain
extended function calls still work in all versions (or I'll perform the
tasks manually, albeit less efficiently).
One example I can think of is the round() function. The $precision
parameter was added in php4, so will not work in php3. However,
function_exists would return TRUE for both 3 and 4, but round itself would
fail if I tried to send a precision level to the php3 server.
Thanks much,
Matt
P.S. Of course the modified function_exists would unfortunately have to
be a recognized function/method in php3 in order for me to call it to check
parameter counts on a php3 server :(
I am sure you have some good reasons for keeping php3 right?
Why don't you consider updating to at least php4 ??
PHPv3 is not even maintained and PHPv4 is not being developed any more.
So by the end of this year (I hope) we will start using a stable PHPv6.
IMHO you should consider changing your code (if this is possible) to a more
mainstream version.

Re: [PHP] German characters Ö,Ä etc. show up as ?
Do they show up as ? just in the web page or in the source returned? Did you check the source of the page? I had this problem before and as far as i remember, i just needed to encode them like oe (have an american keyboard ;-) ouml; etc. If it's a literal ? in the source, it's PHP and you might need to set your php.ini in some way to support your character set. Have a look into Unicode as well. I haven't had this problem for a while since i don't live in Germany anymore, but i'm sure i will probably come across this some day ;-). Good luck!

Re: [PHP] How can I use a function's default arguments but change one of the end ones in the list?
I've thought about this problem before but couldn't think of a solution either. How does func_get_args() solve this? You could make a wrapper function without that. How would u (php) know which parameter u mean in a particular case? I think it would just be useful to have an IDE that can write out the default parameters on a keyboard shortcut or mouse click and then u can change them afterwards.

Re: [PHP] Question about version control.. sorta..
I use GIT and Subversion. Subversion is still a bit hard to use (branching etc) and not distributed but that was before i knew about GIT :-P. You have a central repository that you need to commit to and it's still quite CVS like (which is really confusing and horrible). GIT is nice and fast and also works in a distributed environment. So, it's great when you are the only one working on it or even if you have developers that don't always have broadband and want to commit to the central repository (when they are connected). It also has a windows port that is reasonably easy to install. Check out the cygwin unix on windows port library. It's great when you want the best of both worlds. Git is a package that you can select in there. I use windows at work and cygwin for all the unix stuff i want to do in windows, like perl, bash etc. It's awesome! Spending $150 on this is not really worth it i think and using a database for version control seems a bit odd. They have a database internally anyway which is optimised for the purpose and stored as files. Databases store the data as files (on disk) as well and only have the benefit that some of the data is stored partially in memory (indeces etc) and speeds up data retrieval (and i believe writing it too)... So give GIT a go. It also has a windows shell extension called 'Git Extensions'. Although you might like the GUI stuff, i think it's a lot easier to fire up a console (cmd or bash) and write git init git add . git commit -a -m your msg From then on, you just have to type: git commit -a -m your msg to make commits. There is lots of help for it on the web which you wont get with a proprietary solution. In general Open Source seems to have better support than closed source (simply because there are a lot more people who are willing to help because they want to and not because they get paid). You can create a central repository relatively easy too and push/pull your commits to your local repository ( http://toolmantim.com/articles/setting_up_a_new_remote_git_repository ). You can also use one of the many repositories out there if you don't want to take care of backups etc. BTW, what do you need incremental backups for in a versioning system? A versioning system is an incremental backup (an advanced one)! You might want to backup the whole repository to a different location but you can safely overwrite that. I think Linus Torwalds did a really good job on that :-). Hail Linus (lol). It's versioning as easy as it can get. Hope this helps someone.

Ok.. so I know about CVS and SVN and unfortunately haven't had as much experience with them as I'd like. I've used them, but always in a really basic sense and always on systems that have already been set up. A friend recently mentioned GIT ( http://git.or.cz/ ) too. But here's my situation.. I deal with dozens of clients. I usually make a backup copy of their site (at least the files, not usually the DB) so I have the latest copy of the site to make changes to. Usually I'm the only one working on the site, but sometimes other people may make changes too. Not so often than we're conflicting with our changes, or if this is a known issue, we make sure to coordinate. What I'd ideally like to do is be able to use a CVS type system to keep incremental backups of the code. So instead of checking code out of CVS, changing it, then checking it back in... I'd like to just do a mass checkin of the whole site and have changes recorded and the ability to look at previous versions with DIFF and all that. And of course the ability to 'check out' a previous set of files by date or revision maybe. I assume you can do this with one of the major version control systems, but mostly what I see with how to use these systems involves checking code out then checking it back in.

[PHP] PHP Linux/Windows Outlook 2003 HTML email problem
Hi All,
We've got a problem with our Ubuntu Linux machine sending HTML emails to
Outlook 2003:
It's an Ubuntu Server (uname -a
Linux CDR2-221 2.6.24-19-server #1 SMP Wed Jun 18 15:18:00 UTC 2008 i686

with the newest version of Postfix installed as the Mail server.
Unfortunately, all emails sent as HTML, using the PEAR library for sending
email like so:
public static function sendEmail($fromEmail, $recipientsEmails, $subject,
$txtBody, $htmlBody = null, $ccEmails = null) {
require_once 'Mail.php';
require_once 'Mail/mime.php';
$message = new Mail_mime();
$message-setTXTBody($txtBody);
if (!$htmlBody) $htmlBody = str_replace(\n, br /\n, $txtBody);
$message-setHTMLBody($htmlBody);
$message-setFrom($fromEmail);
if ($ccEmails) {
if (!is_array($ccEmails)) $ccEmails = array($ccEmails);
foreach ($ccEmails as $cc) {
$message-addCc($cc);
}
}
//$message-addCc(m...@insiteorg.com);
$message-setSubject($subject);
$body = $message-get();
$headers = $message-headers();
$mail = Mail::factory(mail);
if (!is_array($recipientsEmails)) $recipientsEmails =
array($recipientsEmails);
foreach ($recipientsEmails as $mailto) {
$mail-send($mailto, $headers, $body);
}
}
arrive with only the plaintext part in Outlook 2003 (and only in Outlook
2003). All other email programs (Outlook 2007 e.g.) seem to work fine with
the formatting.
This only started happening on the Linux machine and works fine when emails
are sent by a windows host or another mail server from the ISP. So i suspect
it must be the setup of Postfix on that machine that is not quite correct.
Other than that, i get the following messages from PHP, apparently the PEAR

Re: [PHP] shell_exec seems to hang other web requests while running convert
We can live with the fact that it will take a little longer to process the images. The image processing is only done by 2 people, about once a month, just to save them time (they would do it with photoshop otherwise and it is really boring and time consuming). In fact, i might set up an automatic email when its finished. :-) In the future it might become an issue when people can edit their own ebooks. This project dates back to 1999, so a lot of it is legacy (a binary page definition data format...). We're thinking of moving to swf pages instead of images, as they currently are, that will reduce the time to be taken to convert a pdf by thousands and would increase the quality and reduce download times for end users, but it will take time to develop which is not at hand atm. We have been thinking about scaling issues as well for quite some time now... It was hard enough to get them to move to Linux, since i work in a .NET shop... Setting up load balancing is not a trivial task though and expensive to host. I'm the main software developer on this project and am too busy adding features and debugging ActionScript, C++ and PHP code to do that as well. Thanks for your thoughts though.

[PHP] shell_exec seems to hang other web requests while running convert
Hi All, The following problem: Our client is converting pdfs to images with a web interface. At the moment I'm using convert from imagemagick with shell_exec (i know i could use the imagick module, but this would require quite a bit of recoding and time at the moment, it was originally running on a windows machine and i couldnt get the imagick module working on that). Is there a quick way to give other web requests to the web server a higher priority than this process? It can take quite a while to convert 100 pdf pages to images in high res with convert. At the moment only 3 images at a time are converted with some crazy ajax logic. But still while these 3 images are converted (can take 20-30 seconds) other requests seem to hang until convert is finished. I know, i can put a at the end of the command line but then they wouldnt know when the process is actually finished. The server is an ubuntu server with the latest release. It's got Apache: Apache/2.2.8 (Ubuntu) mod_mono/2.0 PHP/5.2.4-2ubuntu5.3 with Suhosin-Patch mod_ssl/2.2.8 OpenSSL/0.9.8g Server at 208.79.206.58 Port 80 Please help.

I know, i can put a at the end of the command line but then they wouldnt know when the process is actually finished. its very common to treat objectives which take more time to complete in an asynchronous manner. typically the http request will place a 'command' into a queue, which is picked up by a cron job. then the user is notified upon completion by an email or some other web page, which they can go to review at a later time. this will not help your server load at all however, if youve only got 1 box. the cron will be running and eating juice that the webserver would like to have. best bet is to scale out by tossing another server in the mix to handle the imagemagick stuff. whether or not you want to keep things real-time or move to a cron-based solution is up to you. -nathan

$users is an array and you are trying to simply put it in a string. $x seems to be undefined ergo it's not printing anything.

Re: [PHP] Variable as an index
OK. I would think it uses more memory then, but doubt it would be slower. Isnt the output buffered in memory anyway though in PHP? Surely the buffer is bigger than 100 bytes (which is about the length of this string). So one way or the other, the memory is used.

Re: [PHP] Variable as an index
Yes, i agree with this. Even if it takes a few nano seconds more to write out more understandable code, it's worth doing it because code management is more important than sqeezing out the last nano second. And then also an $var = Hello; echo $val World; has less characters than and is more readable than $var = Hello; echo $var . World; So it would take maybe a few nano seconds less to read it from the hard drive. And we all know that disk I/O is more expensive than pushing around variables in main memory in terms of time.

I'm confused. The function you need is the one you mention in the subject.
All you need to do is create a function that compares two of the objects, in

usort function - it doesn't care what type of thing is in the array. Full
details available at http://php.net/usort.
I just ment to say it would be nice to have it like in Java or C# where you
can implement an interface, called Comparable and define a function in the
class called compareTo which returns an integer smaller, equal or greater
than 0 by which elements can generically be sorted by in a collection. Since
PHP has arrays (hash maps) as the primary collection type, and they are very
good for storing sets or other collections, it would be nice to have a sort
function that would look, if the elements of the array have a compareTo
method (implement the Comparable interface), and if they do, then sort with
that. I find it a bit surprising that such a well designed programming
language doesn't have such a useful feature. I guess one could use one of
the gazillion libraries out there to do the same thing. Also, one could
argue that this further checking would slow down functions that are
primarily used for sorting strings. However, the answer could be also in the
ArrayObject class which is in php natively. Only it should implement all the
array functions that are there anyway, which shouldnt be too hard to do for
the PHP PL developers. Some more in depth documentation of that class would
also be helpful.
Anyway, I found a not perfect, but good enough solution:
Implement a static compare function in the class of the object and put a
function in my library, that is simply called myTools::sort that will get
the object class of the first element of the array (if there is one) and
sort according to the compare method implemented in that class (if it
exists), otherwise just use sort. The compare method takes the parameters as
self:
public class AClass { // implements Comparable {
public static function compare(self $obj1, self $obj2) {
return strcmp($obj1-prop1, $obj2-prop1); // e.g.
}
}
That way I will get an exception if there is an object in the array which
does not have that class, but i can live with that. At least i'll get an
exception and not another funny error, because the parameters are self,
right?
It might be better to define an interface called Comparable with that
method, but was not really necessary for my case.
Just a few thoughts to maybe improve PHP in the future. Hopefully there will
be a lot of interfaces and objects for collection types at some stage in PHP

You can already do what you want. Implement it yourself. Not everyone
wants this level of cruft and inefficiency.
Inefficiency for me is when it takes longer to code. For one second of
coding time I can waste 1000ms of processing time without any cost. Think
about what a computer can do in 1000ms. Calling a function generically takes
next to nothing in processing time (maybe 0.5ms or less. In fact some db
queries take less than that in my experience...

It's very quick to do stuff in, even if arrays are not always the ultimate data structure, they're easy to handle with all the nice functions in PHP... Even if you go full-blown with an Interface and static methods that have to be fleshed out in the implementations, you're still talking about an hour or so. Quit complaining and start typing. :-) I wasn't complaining at all. In fact, it was a suggestion to think about. I don't have a problem with someone proving me wrong. In fact, if i would think I was always right, i wouldn't write to a mailing list to hear what other people think. ;-) PHP is a scripting language. Well done. I wasn't aware of that :-) Everytime the compiler has to parse the source. No. The source is compiled once, and your callback is a PHP function pointer passed down to the C function for usort. That C function has to call back out to the PHP function pointer. That is slow compared to a all native C, perhaps, but it's not re-compiling your PHP source function on every call to the compare function. Even if you are comparing across script calls, APC or ZendCache or similar will compile once. The slowness isn't even in the compiling anyway, really. It's in hitting the disk drive to LOAD the PHP source. It's just as easy to cache the parsed byte-code as it is the source, and it saves a few more cycles, so the caches store the byte-code; But the real savings is not hitting the hard drive to get the PHP source. You can not except true OOP performance. If you REALLY want performance, OOP has enough overhead that you can re-factor to strictly procedural or functional and squeeze out a bit more :-) OOP has less overhead in development time, which is a lot more expensive than processing time these days. The overhead is O(n). It depends more on your algorithm than on the way you write functions or the PL i think. In fact, in some cases the processing would be quicker to not write a function for a few lines of code. I try to write everything in a function to make it more readable and maintainable, because that is what really counts, i think. Not too many device drivers written in C++ For device drivers performance is more crucial than for end user applications. Each ms or even ns you save in a device driver can save you a multitude in an application (the worse the app code, the more important the performance of the device driver). OOP behavior is okay. If performance is the main factor, an C extension will do that. If you're sorting anything large enough for performance to be the main factor, it probably belongs in a database, actually... Yeah, agree. Whenever i can write a query for something, i do that instead. In this particular case i had at hand however, it was a lot easier to do the things i wanted when the data (after a rather complex query) is in memory. Only maybe up to 20 records which shouldn't be too bad. I know somebody somewhere has some custom PHP extension to prove me wrong, but that's going to be the exception. What is the exception?

The scripts executing the task update a status JSON file in the tasks' working directory, which is the only thing being read by the browser after it's kicked off the import process by calling the daemon server with the list of files to import. i've taken a look at popen() and think i can indeed get it to work with that.. i'll let you all know in this thread where to view a demo, when it works :) Cool, would like to see it in action.

Cron calls a php controller daemon script (if it aint runnin yet), which reads the various open tasks, and executes one task step (convert import a single media file) at a time for each open task. It terminates after no more tasks have steps to do. The scripts executing the task update a status JSON file in the tasks' working directory, which is the only thing being read by the browser after it's kicked off the import process by calling the daemon server with the list of files to import. i've taken a look at popen() and think i can indeed get it to work with that.. i'll let you all know in this thread where to view a demo, when it works :) Cool, would like to see it in action. In case you haven't thought of this and it's relevant: If ffmpeg is writing out a file and you can estimate the final size, you could check the file size, if it's growing that is, and compare it to the estimated final size to show the progress. Maybe not the best solution but if there is nothing else. i've thought of it, and considered it too random to even try to estimate ;) OK. So you have tried converting a couple of vids and the resulting file size is always random? Surely there must be some kind of relation to the input file size, the transcode parameters and the output file size. Of course it also depends on the nature of the video but you could also take into account the file size and the time it took to get to that file size (during the process) in relation to the input file size. If you don't mind, i would like to know some good parameters for ffmpeg to convert video files to flv format. Might use it in the future. $cmd = 'nice -n 19 ffmpeg -i '.$sourcePath.' -b 500 -acodec mp3 -ab 192 -ar 22050 -y '.$destination.''; that's what i'm using now. it spits out files larger than the divx originals that i'm using for testing purposes. -b number is used to set the quality and size of the output flv usefull too; http://www.catswhocode.com/blog/19-ffmpeg-commands-for-all-needs Thanks. -- Tim-Hinnerk Heuer http://www.ihostnz.com

My point: Not trying to make one, or any sense either, because im probably contradicting myself here as are all of you, no offence. However, I find the big bang theory more convincing than any 7 days creation theory or things like that (sorry to all the religious people out there), But then you can always ask what was before that and before that and so on. But no one ever asks who or what created god in the first place, if s/he/it exists. Was s/he/it always there? Well then one could argue that the universe was always there too and there was no creation or big bang, or was good there for infinity and after a few quadrillion years, s/he/it became so bored and decided to make a big firework or only spend 7 days in creating everything? 7 days is a horribly short time for such a task after an infinite time of boredome. Maybe earth was always there (although this seems unlikely too). But do we really know that? I mean, ive read it in a book and learned it at school, but maybe we're all wrong and its all totally different to what is expected.

[PHP] pear Mail/Mime problem on new Ubuntu Linux server
Hi All, Can someone think of a reason why when changing from a Windows 2003 Web Edition server running PHP 5.2 to a Ubuntu machine, also with PHP 5.2 can cause the following problem: The emails sent from the server, which should be in HTML format (the client wanted this specifically) now only show the plain text email, but only in Outlook XP or 2003. The Outlook 2007 on my work machine receives it fine, also my gmail account. Unfortunately, the client uses the Outlook version with the problem. Might it be the Unix newline characters? My first suspicion was to blame M$ for letting Outlook check the headers for example.com, postfix or Linux, but that might be a bit exajurated paranoia. lol Thanks for even reading this, even more for replying. :) Tim

glob()
http://www.php.net/glob
How portable is glob?
How fast is glob? Being that it searches through the entire filesystem,
this could potentially take a long time (like if i have wildcards early in
the filepath pattern and lots of matches) correct? If my file variations
(wildcards) are just at the end of of the filepaths and i don't have more
than 1000 files in the directory then will I most likely be 'alright' with
glob (in terms of time)? I have probably spent more time now 'considering'
the time implications of glob, than glob actually would consume when
operating...
Thanks for the quick response/solutions.
dK
Glob works on all platforms.
Glob does suffer from performance issues above a certain number of files,
and this can be system dependant. If you're unsure how many files it may
return you'd be better using opendir/readdir.
Not sure where you got the idea that glob searches the entire file system,
but it's limited to either the current working directory or the directory
you specify. So if your PHP file is in /var/www/htdocs and you do
glob('*.txt') you'll get all .txt files in /var/www/htdocs. And if you do
glob('/tmp/*.txt') you'll get all .txt files in /tmp.

[PHP] usort for sorting an array of objects
Hi Guys, I need to sort an array of objects. I found this ( at a url that didnt let me send this msg... ) and I would know how to do it, but I believe there might be a cleaner, more elegant way to do it. In Java, you just need to implement the interface Comparable and provide a method called compareTo (as far as i remember) and then you can use one of the many sorting algorithms generically on objects that are comparable... Anyway, I didn't find something like that for PHP. Since I'm using symfony, I had a bit of a play with the objects at hand and simply did a sort($arrayOfObjects) and it did sort them by the id. Just wondering where it got the information on what to sort on (not quite) correctly for my case?

You get this error because you are trying to include a php file in the
apache configuration. Apache config files have tags, such as Directory and
?php looks like it's opening an Apache directive but not closing it with
?php ... /?php
If you want to include php scripts in your php file, you should do that
there, e.g. in incfiles.php:
?php
require_once('file1.php');
require_once('file2.php');
...
Or if you want to include a whole directory, read it with readdir (would
have to look up the function name etc) and iterate over it.
If you have classes you can also use the feature that i really like, called
class autoloading ( http://nz2.php.net/autoload ).

I make conclusion that I need separate component with object-oriented API to have possibility of running unit tests and to have logically structured code, which I could work with without confusion.
