[PHP] Re: PHP: inexplicable behaviour of pre- and post-increment operators
Mess
Dne 27.2.2010 5:01, clanc...@cybec.com.au napsal(a):
A week ago Dasn asked a question about converting arrays, and I quoted one
possible way of
achieving his task, using the operation:
$i = 0; while ($i $k) { $b[$a[$i++]] = $a[$i++]; }
I added the comment that I have always been wary of using statements like this
because I
was unsure when the incrementing would occur, so I tried it.
I received several CC e-mails replying to this post, including one rather
critical comment
to the effect that pre-and post-increment were all quite simple, and I really
ought to
learn the fundamentals before I started trying to do anything elaborate.
I posted a reply to these e-mails, but as neither they, nor my reply, or any
follow-up
discussion ever appeared in the discussion group I will repost this reply. (I
did have a
power failure at this time, so it is conceivable that any follow-up was lost as
a result
of a glitch in my mailer, but I think it is more likely that there was a glitch
in the
discussion group server.)
Unfortunately things aren't nearly as simple as this writer believes. The rule
I have
always used is that if you use the same variable as an index on both sides of
an assign
statement it is not safe to change the value of the index within the statement.
While I
have achieved the result I wanted in the example above (using PHP 5.1.6 --
there is no
guarantee it would work with other implementations of PHP) the results of doing
this in
the general case can be quite inexplicable.
The particular case which prompted my comment was the one where you want to
copy part of
one array into the corresponding elements of another array. In accordance with
my rule, I
normally write:
$i = 0; $j=count($a); while ($i $j) { $b[$i] = $a[$i]; ++$i; }
It is tempting to try to put the increment into the assignment statement.
Clearly the
value of $a[$i] has to be read before it can be written to $b[$i], so the
logical
expression would be:
while ($i $j) { $b[$i++] = $a[$i]; } A.
However if you try this, you get $b[1] = $a[0], and so on. But if you try the
alternative:
while ($i $j) { $b[$i] = $a[$i++]; } B.
You get $b[0] = $a[1], and so on (as you would expect).
Out of curiosity, I then tried:
$i = -1; $j=count($a) - 1; while ($i $j) { $b[$i] = $a[++$i]; }C
This gave the desired result, and seemed moderately logical. However when I
tried:
$i = -1; $j=count($a) - 1; while ($i $j) { $b[++$i] = $a[$i]; }D
This gave exactly the same result. It is quite impossible to explain the
results in cases
A and D from the definitions of the pre-and post-increment operator, so I think
I will
stick to my safe rule!

Thanks for reply, but I want to:
unset($ARR['a']['b'])
Imagine I have this:
$KEYS = array('a', 'b', 'c');
And I want to:
unset($ARR['a']['b']['c'])
It's probably impossible, unless I do something dirty like this:
list($rootA, $rootB, $rootC) = $KEYS;
if (isset($rootC)) unset($x[$rootA][$rootB][$rootC]);
elseif (isset($rootB)) unset($x[$rootA][$rootB]);
elseif (isset($rootA)) unset($x[$rootA]);

Assuming 'content' changes, and this is the cut-down example...

There's a small overhead in opening/closing the file three times
instead of one, but I doubt that's going to be an issue for you.
I am not appending anything, just ensuring that it will be written (and
giving it max. 3 tryes).

you create directories like:

s/
s/some-subdomain.freehosting.com/ (this includes CONF.php, where you
store some basic infos)
Everytime visitor hits the page you do:
@include('t/test-subdomain.freehosting.com/conf.php')

Re: [PHP] Re: XSS Preventing.
Cons: 1. Can't easily edit information in the database True, so if you use phpmyadmin for editing - don't do what I suggested. 2. Can't display raw for the user (e.g. edit a forum post) Edit a forum? You display the data in TEXTAREA... 3. Uses more space in the DB True, although I use htmlspecialchars() which doesn't replace that many characters. 4. Isn't as easily indexed 5. Breaks il8n support of internal search engines (sphinx, lucene, etc.) Thanks for reply, I will still do it before the DB insert. * Btw. I should have mentioned I don't use htmlentities(), but htmlspecialchars()* You're NEVER supposed to santize before inserting in the DB. Ever. Regarding the performance boost, if your application is written so well that calling htmlentities() is hurting the performance, I bow to you as writing the highest performing PHP I've ever seen. I would bet money that validation and sanitization, even if overdone, wouldn't take more than 2 or 3 percent of execution time. Do NOT do this, OP, it's terrible practice.
Re: [PHP] Re: XSS Preventing.
Eddie Drapkin napsal(a): 2. Can't display raw for the user (e.g. edit a forum post) Edit a forum? You display the data in TEXTAREA... Because seeing something like: textareaquot;Yeah!quot; is what he said. /textarea Is awesome for the user experience. If you don't do html...() before putting to textarea this can happen: textarea blabla b/textarea blabla /textarea See? 3. Uses more space in the DB True, although I use htmlspecialchars() which doesn't replace that many characters. That makes it no better of a practice to pre-sanitize. You've still yet to offer any compelling reasons why you think this is a good idea. It's DEFINITELY easier to store RAW data to DB, because it won't give you any headaches in the future - when you might need to add some other functionality requiring this. But for me personally is doing - htmlspecialchars() - BEFORE the DB insertion the choice to go, because I am looking for performance. ok? respect

If the query stopped after getting 2 entries then this has nothing to do

what Miller meant, he most probably solved it already...
Andrew Hucks napsal(a):
When you say die, does it just stop, or do you get an error message?
Depending on how long it's taking to perform the action, the script
will stop just because it's taking a while. (by default, I think it's
30 seconds.)
If so, use: ini_set(max_execution_time, time in seconds);

[PHP] Resampling images -- need lock ?
I have 10 images of different sizes.
If user clicks ROTATE, a script will go through all these 10 images and
rotates them.
If the user clicks TWICE, the first script will get aborted in the
middle (so few images are already rotated) and then the second request
will rotate all of them again.
I probably need to write a script that would lock the first file and if
this file is already locked it would just die('already working...')

I know I can use javascript to disable second click, but I want it
server side.

Well, few images (etc. 5) got rotated +90 deg. and then the script got aborted, because of the second request, which will cause another +90 deg rotation again on all images = meaning those 5 will be again rotated +90 = 180, the others stay 90. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Which hashing algorithm is best to check file duplicity?
Fastest depends mostly on the size of the file, not the algorithm used. A 2gig file will take a while using md5 as it will using sha1. Using md5 will be slightly quicker than sha1 because generates a shorter hash so the trade-off is up to you. $ ls -lh file.gz 724M 2008-07-28 10:02 file.gz $ time sha1sum file.gz 4ae7bd1e79088a3e3849e17c7be989d4a7c97450 file.gz real0m3.398s user0m3.056s sys0m0.336s $ time md5sum file.gz 16cff7b95bcb5971daf1cabee6ca4edd file.gz real0m2.091s user0m1.744s sys0m0.328s $ time sha1sum file.gz 4ae7bd1e79088a3e3849e17c7be989d4a7c97450 file.gz real0m3.332s user0m2.988s sys0m0.344s $ time md5sum file.gz 16cff7b95bcb5971daf1cabee6ca4edd file.gz real0m2.136s user0m1.776s sys0m0.348s Aha, thanks for sharing the benchmark.

echo 'http://mzvarik.com/foo?somevar='.urlencode('script
type=text/javascript/*evil code here*//script');
send url to unsuspecting users of your site. anyone know clicks the URL
has just had their cookies hijacked.

There's a PHP configuration that cookies are available on HTTP side

[PHP] Re: PHP/Apache: script unexpectedly invoked multiple times in parallel every 30 secs.
Marc Venturini napsal(a): Hi all, I wrote a PHP script running in Apache which takes more than 30 seconds to complete. It uses set_time_limit() to extend the time it is allowed to run. The script generates thumbnails from a list of images. Upon completion, the script redirects the browser to another page using HTTP headers. If you die() at the end of the script and don't redirect does it continue this auto-30-seconds execution? On my local machine (Windows + EasyPHP), the script runs as expected and completes after a few minutes. I observe an unexpected behavior on my production web server: - The script runs as expected for the first 30 seconds. - After 30 seconds, the same script with the same parameters starts again in a new thread/process. The initial thread/process is *not* interrupted, so 2 threads/processes run in parallel, executing the same sequence of operations with a 30 time shift. - The same scenario happens every 30 seconds (i.e.: at 030, 100, 130, and so on), multiplying the parallel threads/processes. - The browser keeps on loading while the above happens. - After some time, the browser displays a blank page and all the threads/processes stop. I assume this is due to resources exhaustion, but I have no means to check this assumption. I deduced the above reading a text file in which I log the sequence of called functions. It all seems as a redirection / unclosed loop problem. Unfortunately I have no access *at all* to my production web server configuration (shared hosting, no documentation). I cannot even read the configuration settings. While I'm considering moving to another host, I'd be extremely pleased to have an explanation of the observed behavior. I have browsed the mailing list archives and looked for an explanation in other forums to no avail. This thread may deal with the same issue but does not include any explanation or solution: http://www.networkedmediatank.com/showthread.php?tid=17140 Thanks for reading, and please do not hesitate to ask for further explanations if what I'm trying to achieve was not clear! Why it works on your local server is probably caused by different versions/settings, but I bet there's an error somewhere in your script. Consider sending it here, I'll take a look. Cheers, Marc.

[PHP] Re: shell_exec - asynchronous would be cool!
German Geek napsal(a): 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. I would exec a script on linux (= multi-thread). That script would do anything what is needed (imagemagick) and then check if there are any processes running on the same session. If NOT than it would call (could be HTTP request also) a PHP script on the windows server. What's the deal?

I agree that you could restrict it to one vote per e-mail address. Obviously, I can't speak for the OP. I've worked with applications where e-mail addresses were limited to a single domain and every user had one, and in those cases the e-mail address made an excellent key. I have also worked in situations where the correlation between people and e-mail addresses was n:m rather than 1:1 or even 1:m. In those cases, the e-mail address was totally unusable as any kind of key. Then there is a broader scope where one decides that, given the lack of a better solution, the overall population is broad enough to tolerate the imperfections since there is no better solution. To go back to what I said in my first reply on this thread, I consider that more about polling and statistics than voting.

[PHP] Re: Unique User Hashes
I don't think there is more precise way to determine the visitor than by
the IP address, and it sucks indeed.
You can't rely on the cookies, can't rely on what's in 'HTTP_USER_AGENT'
... as said: registration could be a solution - but it's an annoyance
for the visitors - although you can try OpenID service.
NOTE:
The HTTP_X_FORWARDED_FOR can contain more IPs, so this is what I use:
function getIP()
{
static $clientIP;
if (isset($clientIP)) return $clientIP;
if (isset($_SERVER['HTTP_X_FORWARDED_FOR']))
{
$forwarded = $_SERVER['HTTP_X_FORWARDED_FOR'];
$ipaddr = $forwarded;
$i = 0;
while (($pos = strrpos($forwarded, ',', $i)) !== false) { // nekdy
jich muze byt vice
$ipaddr = substr($forwarded, $pos+1);
if (!$ipaddr) {
$forwarded = substr($forwarded, 0, $pos);
} elseif
(preg_match('/^(?:25[0-5]|2[0-4]\d|1\d\d|[1-9]\d|\d)(?:[.](?:25[0-5]|2[0-4]\d|1\d\d|[1-9]\d|\d)){3}$/',
$ipaddr)) {
return $clientIP = $ipaddr;
}
}
}
return $clientIP = $_SERVER['REMOTE_ADDR'];
}
I doubt you find better solution than what you use now, but let me know
if so,
Martin
Ian napsal(a):
Hi,
I am busy building an application that requires one time voting and to get
around the user deleting a cookie that I set im keeping a hash on my side
which I then try match before allowing anything.
This is how I currently generate my hash:
/* Get vars */
$browser = $_SERVER['HTTP_USER_AGENT'];
$ip = $_SERVER['REMOTE_ADDR'];
$real_client_ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
if(!empty($real_client_ip))
$name = gethostbyaddr($real_client_ip);
else
$name = gethostbyaddr($ip);
/* Return generated hash */
return md5($browser.$ip.$real_client_ip.$name);
Now thats not ideal because you can just change your user agent and vote
again - but IP isnt good enough either because in South Africa due to the
poor internet we all connect to international sites via a series of
Transparent proxies which makes everyone seem to come from one IP.
Anyone had to deal with this in the past and does anyone have any
suggestions/ideas as to how I could better this setup?
Many thanks in advance,
Ian

Joe napsal(a):
Is it possible to use a PHP operator as a callback? Suppose I want to add two
arrays elementwise, I want to be able to do something like this:
array_map('+', $array1, $array2)
but this doesn't work as + is an operator and not a function.
I can use the BC library's math functions instead:
array_map('bcadd', $array1, $array2)
but that is an ugly hack that might break if the library is not available.
I can create an anonymous function:
array_map(create_function('$a, $b', 'return $a + $b;'), $array1, $array2)
but that seems really unnecessarily verbose.
Is there any simple clean way to do it? Thanks,

Hi,
I'm building a login system with AJAX/PHP/MySQL.
I have worked everything out... AJAX is sending request to a php login
script (login.php) who if authentication passes initializes the session and
sends the header using header(Location : registered_user_area.php);
The whole system works great without AJAX, but when I put AJAX in the story
I ahve one problem:
1.When the user is successfully authenticated the login.php sends the
header, but the AJAX XMLHttpRequest call is still in progress waiting for a
PHP response. So when PHP using the header function redirects to another
page that page is outputed to the login form...
My PHP login snippet is:
if ($res_hash == $u_pass) {
$logged_user = $sql_execution-last_query_result-user;
$sql_execution-exec_query(DELETE FROM seeds,false);
$sql_execution-db_disconnect();
session_start();
$_SESSION['user'] = $logged_user;
$host = $_SERVER['HTTP_HOST'];
$url = rtrim(dirname($_SERVER['PHP_SELF']), '/\\') . '/mpls/index.php';
header(Location: http://$host$url;);//--That page
($host$url) is outputed in the login form...
exit();
}
else {

$sql_execution-db_disconnect();
echo 'BLS';//--This is sent when the password/username is

Hi there,
While this question can spur some neat solutions, it raises a red flag
in that if you need to do this, you probably need to rethink things a
bit.
In cases like this it is easier for people to help if you describe the
actual problem you are trying to solve, not how you think it needs to
be solved. It could be that you don't really need weird (but
beautiful, like Jim's idea) solutions. If you explain why you believe
that you need to do this in the first place, maybe someone can suggest
something else which doesn't require a weird solution (however
beautiful).

This benchmark is not very accurate, but you are right the database connection took most of the time. Shopping cart is stored in session - not in database. I am half-way doing the eshop I bet it will took much more than 0.01 sec to generate the final version. I was going to make this file cache system, but I relies that for each page like (?page=News, ?page=Products etc.) these HTML blocks (Navigation, Recommended) changes and that would mean I would have eventually like 50+ cached files. One way or another I will always need to connect do database (I cannot cache 300 products in 300 files, can I?).

[PHP] MySQL - HEAP table type
Hi, I am sorry for this not being really a PHP question, anyway I use MySQL database, I have a table, which is HEAP (memory) type and I found out I can store only about 22000 entries in it, then when I want to insert new entry it gives me an error that the table is full. The question is: How can I increase this limit? Thanks, Martin Zvarik -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Session - when they expirate ?
Hi, I was looking all over the internet and I don't understand when and how does the PHP session expirate. I suppose that it happens when the user is inactive. On my website I don't use cookies for session and it has standard php.ini configuration: session.gc_maxlifetime = 1440 session.gc_divisor = 100 session.gc_probability = 1 session.cache_expire = 180 So, does this mean, that if the visitor is 180 minutes inactive it automatically deletes the session ??

[PHP] PHP Standard style of writing your code
Hi, I see everyone has its own way of writing the code. If there is 10 programmers working on same thing, it would be good if they would have same style of writing the PHP code. So, my question is: Is there anything what would define standard style of writing PHP code?

Replace every \n with linbreak and every \r with linefeed with str_replace And probably you see where the problem is It's because of the operation system. Win32 and Linux works different.

[PHP] MySQL close connection, what's the purpose?
Hi, I was wondering why is it necessary to use mysql_close() at the end of your script. If you don't do it, it works anyways, doesn't it? MZ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

If you don't do it, it works anyways, doesn't it? Yes, but... Suppose you write a script to read data from one MySQL server, and then insert it into 200 other MySQL servers, as a sort of home-brew replication (which would be really dumb to do, mind you)... In that case, you REALLY don't want the overhead of all 200 connections open, so after you finish each one, you would close it. There are also cases where you finish your MySQL work, but have a TON of other stuff to do in the script, which will not require MySQL. Close the connection to free up the resource, like a good little boy. :-) There also COULD be cases where your PHP script is not ending properly, and you'd be better off to mysql_close() yourself. So, does the connection close automatically at the end of the script ? My situation is following: I have a e-shop with a ridiculously small amount of max approved connections, so it gives an error to about 10% of my visitors a day, that the mysql connections were exceeded. Now, if I will delete the mysql_close() line, will that help me or not? My webhosting does not allow perminent connections either.

[PHP] Upload with process meter
Hi, is it possible to upload a file and see the process of uploading (before the file is uploaded, there is something showing from 0% to 100%) using PHP and Javascript ? I saw some applications in Perl and mostly in JAVA, but I also found out something about some extension for PHP, but i think it wasn't complete at that time. Thanks for sharing your knowledge about this... :) Martin -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Script Multitasking
Hi, I have a file, which I run using command line. The file I am running, runs several files using passthru(). What I realise is, that it runs each file in sequence and waits for its result. I need to run all files at once and they don't have to return the result to the main file. How do I do this? Any help appreciated!

[PHP] Themes, pictures directory
Hi, I have a website, which uses themes. The web tree looks like this: * webroot o *themes* + default # images + red design # images o *index.php* Let's say I choose red design theme. All the pictures the theme is using will have URL like www.site.com/themes/default/images/bla.jpg. Is there a way how I can change it? So noone can see I have themes in that directory? I was thinking about: ShowImage.php?blah.jpg, but that is too slow... :-/ Any help appreciated. Martin
