[PHP] Running PHP from inside another application!
Hi, I've a case where I have to run a lots of php-scrips, in a short time, from inside a delphi-application. Every script connects to the same databas. Today I use CreateProcess to start php.exe and then I'm using pipes to get the php-result. I'm doing this for each php-script I want to run, and it's timeexpensive because every script has to establish a database-connection. I'm new in the PHP-world, but I'm sure that there is a better way to solve this case. I would prefer NOT to run php.exe all the time and of course I want to use the same databasconnectio, but I don't know how. It's not an option to put all the scripts into one big script.

[PHP] mediator between PHP and Perl (with sessions)
Hi... I got a shared lib API written in PHP, that depends on sessions for its operation. I took a prepared system in Perl that I want integrate with the shared lib API in PHP. What I thought about is, to write a mediator class in Perl that will define the same API functions as I got in the shared lib API in PHP. I do not want to imitate the API functions workflow in Perl, but instead call the shared lib API in PHP from Perl (this way I don't have to maintain 2 class APIs in different languages). I thought of making a PHP script that can run on shell and return serialized output of any API function in the shared lib. Then call that script from Perl and process the returned output in Perl. Problem in this way is, that the shared lib in PHP uses sessions which are un-accessable from a shell script. And I cannot put that script on the web, since it returns sensitive data. Is there a way to use sessions variables in PHP shell script (without reading the session file and parse it in the script)? If anyone is familiar with any other implementation of such a mediator, please tell. -thanks, Eli. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] User Passwords: checking for unique chars
[ snipped ] Oh! You're so mean!! ;) A lot of people are making some great points. I feel I must strighten this out a little. While I may not be the best coder in the world I do have my reasons. I originally made the passwords automatically generated and emailed to the user. Nice complicated ones! I was immediately shot down for doing this because no one here liked the idea of having complicated passwords! I was told to allow the user to chose their own so I merely wanted to make sure no one could have stupid passwords like aaa. So I just added a few limitations. Besides, my small website doesn't hold any sensitive information about anyone so it wouldn't be the end of the world if some cracked it! Try something like http://sourceforge.net/projects/pwgen/ which generates passwords that are easy for humans to remember, yet not that dumb. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Image Creation
I just wrote a little script to play around with the GD library but I am
having a problem displaying it in the browser. I have not problem at all
when I just run the script. But I was trying to make the image in a custom
function which will return the image when its called. All I end up getting
is a bunch of weird characters.
Here's my code:
function makepie($slice, $total){
$height = 150;
$width = 150;
$im = ImageCreate($width, $height);
$bck = ImageColorAllocate($im, 255,255,255);
$black = ImageColorAllocate($im, 0, 0, 0);
$red = ImageColorAllocate($im, 255, 0, 0);
imagefilledellipse($im, 75, 75, 125, 125, $red);
imageellipse($im, 75, 75, 125, 125, $black);
//Making the Slice
$pieslice = (($slice / $total) * 360) + 315;
imagefilledarc($im, 75, 75, 125, 125, 315, $pieslice, $black,
IMG_ARC_PIE);
//Return
header(Content-type: image/png);
echo ImagePNG($im);
}
Anyone have any idea why I cant return the image?
Thanks

Hi

I am new to php, I would need some detailed instructions, or point me to an
opensource php script which already does that so that I can analyse it.
In a single script it could be a little nasty if you want more then one
or two phases - its common to have a submit and view result on the same
script, but multiple stages can become a maintaince nightmare, but you
can do it like this:
You could use a mode indicator and a session settings. Look for
start_session() in the manual.
Something like:
?php
start_session();
if(!isset($_SESSION['mode'])){
$_SESSION['mode'] = 0; // first time round, on first screen
}
// function to test if mode is 0 AND button pressed (ie a submission,
// deal (store) the information and increment mode
if($_SESSION['mode'] == 0){
?
form 1 /form 1
?php
} else if ($_SESSION['mode'] == 1) {
?
form 2 /form2
?php
}

[PHP] Re: who's on-line application - php
Hello, usually you can not determine clearly who is online on your website at the moment because http is a session-less protocol (thus php implements a session mechanism through cookies or session id). However you can use the following approach: - add a 'last_seen' field to the users table of your website - update that field for the user everytime he calls a page on your site (e.g. include(updatels.php); on every page) - to get the number of (probably still) online users do a 'select from user_table where now()-lastseen 3 minutes' another method would be changing the session handler to store session data in the database and query the sessiontable appropriately. best regards, Stefan Dengscherz On Mon, Feb 14, 2005 at 04:30:32PM +0200, Jacques wrote: I would like to indicate the particulars (from a MySQL database) of all those users that are currently on-line (those whom have successfully signed in).

Encoding / closing the source with one of the packages out there is an option. The license that you use is important and always be certain that LICENSE is included in every code distribution. Without knowing a little more about the exact product you sell it's tough to give good advice, but some things that I have seen: - Open up part of the source, but keep the valuable code closed - Different licenses for different parts of the code - Open source it all and charge for 24/7 support services - Open source it all and charge for consulting / specialty services - Open source it all, but only for a client application. Then you have the client connect to a server side app on your site and you charge per usage. My advice: look at some of the *successful* and more importantly *profitable* open source companies out there. -- Teach a man to fish...

[PHP] How to make use of the billing token the right way???
I created the token via Javascript where the billing can be controlled better and to prevent the mixed up of the billing such as incorrect statements or calculation. I use the billing lock file for that purpose. I found that it doesn't alway work that way when the browser is refreshed or submitted, so I customized the Javascript to make it work better. That solve my problem but I found that some browsers acted too soon or too late with it's use of Javascript coding to unlocking the file, so the billing lock doesn't get released. So, I decided to do it all in PHP so the browsers' issues can be removed. I haven't decided how to best make use of the token via PHP, so I'm wondering if anyone of you can come up with one that is better than what I can come up with. 1) A token is a file with machine's IP address and time-stamp. 2) The machine's IP address is in charge of hte token until released. 3) If the machine with the same IP address opened another browser window, that 2nd browser window can't have the token because the 1st browser window are using it. Even though it is the same webpage regardless of what part of billing it's in. (This one I have trouble with).

[PHP] Re: PHP 5 with Apache 2.0
* Neal Schilling [EMAIL PROTECTED]: I know this question probably gets asked a lot, but I'm setting up a Web Server shortly and am debating going with PHP 5 on Apache 2.0 or 1.3. In short, is PHP 5, when combined with either Apache 1.3 or 2.0 on Linux or FreeBSD, ready for a production environment? This is, of course, an opinion, but back your opinion with as much fact as possible. I read a blog entry by a PHP/PEAR developer that stated the following: Serving PHP via Apache 2 is 27 percent slower then via Apache 1 DSO and 31 percent slower then Apache 1 static. (http://ilia.ws/archives/32-Apache-1-vs-Apache-2-Performance.html) The flip side is that apache2 is faster at serving static content, both in compressed an uncompressed form. Make your own conclusions. Basically, the big benefit of using apache2 is threading support -- but PHP4/PHP5 are not considered threadsafe -- not because PHP isn't threadsafe, but because a number of the libraries against which it *may* link may not be threadsafe. So, when you run PHP in the apache2 prefork mode, you lose all the threading benefits. Also, if PHP 5 is NOT ready, do you feel PHP 4.3 is ready for production with Apache 2.0? As far as I know, the same issues are present for PHP4 as PHP5 when using apache2. -- Matthew Weier O'Phinney | WEBSITES: Webmaster and IT Specialist | http://www.garden.org National Gardening Association| http://www.kidsgardening.com 802-863-5251 x156 | http://nationalgardenmonth.org mailto:[EMAIL PROTECTED] | http://vermontbotanical.org -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

What I've Tried So Far:

the manual and this list's archives under the terms array,
concatenate, convert, append and string in various combinations.
However, while I learned some interesting tips on a variety of topics, I

[PHP] Re: Image Creation
Thanks for the compliment on my function. I have since improved upon
it...see below.
I can do the exact same thing as you and get results, but what I can't do is
show the image within an HTML table. I think it is something to do with the
header line, but I dont know how to get around it. I've tried just calling
the function like I have in the code below. I've also tried calling the
function inside of img command. Both ways dont work.
Check out the code if you can and let me know if you seen anything that I am
doing wrong. Thanks

Dude - that works fine!
can you check your code - make sure you havnt got any white space at all
before the php starts in ANY file, and then check that you've got ALL
erros being reported (because you might have the error cant send headers,
output allready sent at line x) which will prenvent the header being sent
and then you dump the image to the screen which is the random wierd
characters (that means the image create functions are all ok and
installed, and you have an image object or similar).
my code was simple ?php {your function} makepie(10,100); ? NO WHITESPACE
NO BLANK LINES NOTHING.
(ps you might even have a php include in the php file (php prepend or
something?) which might be inserting a space or a newline or ending
headers or something. Look at error_reporting() or similar in the manual
to turn error reporting on for your script.
Hope you find the bug, thats quite a nice function you have there.

Everything looked good up to here.
$tantoEmail = $tantoEmail . , . $tantoData['email'];
I'm not that great at SQL syntax, but this should work. That'll at
least get your e-mail addresses in there. The next problem is that,
and for purposes of demonstration we'll say you pulled out three
addresses, you're going to have a comma before the first e-mail
address.
i.e.
,address1,address2,address3
because the first time through the while, $tantoEmail is empty, then
you put a comma and the first address.
So, you'd need to $tantoEmail = ltrim($tantoEmail, ,); that.
You can further shorten that to:
$tantoEmail .= , . $tantoData['email'];
but you'd still need to ltrim that to get rid of the first comma.
Another way to do this to avoid having to worry about that pesky
comma.
while ($tantoData = mysql_fetch_array($tantoResult))
{
if ($tantoEmail != )
$tantoEmail .= , . $tantoData['email'];
else
$tantoEmail = $tantoData['email'];

now all the values are stored into an array ($tantoEmailArray). to convert

You could maybe put the @ in front of the $cmd:
@$cmd = $_POST['cmd'];
However, I think it would be most clear to do:
$cmd = isset($_POST['cmd']) ? $_POST['cmd'] : NULL;
You can then rest assured that $cmd *IS* set in the rest of your script.
It's a bit lengthy, but at least it's all on one concise line, and you can
easily copy/paste and comment in/out the line.

Re: [PHP] [NEWBIE] Trying to combine array into one string
Dave wrote:
The Situation:
I'm retrieving some email addresses from a database. I want to be
able assemble all the addresses into one string that I can use in the
mail() command. At no time should there ever be more than about 5 email
addresses collected from the database. I want all addresses to appear in
the To: field so everyone receiving the email will know who else has a
copy.
I believe some mailers may have trouble with more than one address in To:
You may want to put the first address in To: and the rest in Cc:
Or you can put an address in the To: field to keep a log of all
outgoing emails, or send it to some account that just deletes all email.
Only Bcc: will hide email addresses.
The Problem:
I can't quite figure out how to take the results of the
mysql_query() and assemble them into a string. In my experiments so far,
I either get a mysql_data_seek(): Offset 0 is invalid for MySQL result
index error, or my mail function sends to a blank address.
The data_seek error is telling you that there were NO results at all in
that data set, I do believe...
What I've Tried So Far:
My own code is obviously flawed in syntax in logic, so I searched
the manual and this list's archives under the terms array,
concatenate, convert, append and string in various combinations.
However, while I learned some interesting tips on a variety of topics, I
suspect I'm missing some essential description that will lead me to the
command I need.
The Question:
How do I take the contents of an array and turn them into a single
string?
http://php.net/implode
will take a bunch of stuff in one array and turn them into a string.
For Reference:
Here is the code I have. I know it's flawed, but hopefully it will
give an indication of what I'm trying to achieve:
--code--
$tantoQuery = SELECT forum_members.emailAddress AS email FROM
forum_members, event_tanto WHERE forum_members.ID_MEMBER =
event_tanto.tanto AND event_tanto.event =' . $show . ';
$tantoResult = mysql_query($tantoQuery);
For debugging purposes, print out $tantoResult:
echo tantoResult: '$tantoResult'hr /\n;
It will either be Resource #1 (or #2, #3, ...) if the query succeeded,
or false -- which will appear as nothing when you print it which is why
I've got that label and the apostrophes there.
while ($tantoData = mysql_fetch_array($tantoResult))
{
$tantoEmail = $tantoEmail . , . $tantoData;
Also print out $tantoData:
echo tantoData: '$tantoData'hr /\n;
You will quickly find out that it's an Array -- which is the ARRAY
returned from mysql_fetch_array. [Fancy that, a function that ends in
'array' returning an array :-)]
All you'll see, however is 'Array' which is not real useful.
So use var_dump($tantoData) to see what's *IN* the array:
echo pre;
var_dump($tantoData);
echo /prehr /\n;
Now you'll see that it is a one-element array with an index of
'emailAddress' to it.
So what you need in your code is something like:
$tantoResult .= $tantoData['emailAddress'];
Except that you'd need a comma separator like this:
$tantoResult .= , . $tantoData['emailAddress'];
But then you've got a bogus extra comma on the front of the whole result,
and that's no good.
You could strip it off with http://php.net/substr, but it's probably more
clean to do like this:
$tantoResult = array();
while ($tantoData = mysql_fetch_array($tantoResult))
{
$tantoResult[] = $tantoData['emailAddress'];
}
So now you've built up this array of the email addresses, and you can use
that implode function:
$tantoEmails = implode(, , $tantoResult);
Note that implode only puts commas BETWEEN the elements it splices
together, so you won't have the extra comma at the end.
}
mail($tantoEmail, $subject, $mailcontent, $addHeaders);
--code--
Any help would be much appreciated.
You're on the right track, but when your script isn't doing what you
think, add in some print statements to see what your data actually looks
like.
Often you can then figure out where you went wrong.
Be sure to print out the data early and often -- Sometimes the problem
you see is really caused every early on in the script.

[PHP] PHP Array question
I have an array with image names like:
$arrayone = array(1.jpg, 2.jpg);
$arraytwo = array(a.jpg, b.jpg);
Then I have a variable for each to count the number of elements:
$arrayoneElements = count($arrayone);
$arraytwoElements = count($arraytwo);
I'm using the element variables to control the loop to display all the array
elements.
This is it:
for($ctr=1; $ctr $elemcount; $ctr++){
if($ctr%5){
echo td width=\20%\a
href=\javascript:popup_pic('.$gallerypath./$arr[$ctr]')\img
src=\.$gallerypath.thumbs/$arr[$ctr]\ alt=\no image\ //a/td;
}else{
echo td width=\20%\a
href=\javascript:popup_pic('.$gallerypath./$arr[$ctr]')\img
src=\.$gallerypath.thumbs/$arr[$ctr]\ alt=\no image\
//a/td/tr\ntr;
}
}
What I want to do is to only show 20 pictures at a time with a Next link
and a Previous link. For the first 20 only the Next link would show and
whenever the last set would show only the Previous link would. Every other
time both would show.
Can someone point me in the right direction on how to count through the
elements until the end and back to display them? I just can't figure it out.

I THINK you MIGHT be able to use some session functions to set the session
name and session file when you do session_start() and get PHP to do all
the work of the reading/writing the files. You just need to pass in the
session ID to session_name() or session_start() or something like that. I
forget how to do this, but I did it once when I couldn't get trans-sid to
work, and it was a one-line solution. Try to find it. Maybe session_id()
takes an optional argument.
If that fails, then here's option 2:
There is sample code for storing your session data in MySQL on the
web-site in the manual.
You could easily take that code and swap out the MySQL bits to just
read/write your own session files, or go ahead and use MySQL if it's okay
security-wise, or put the data anywhere you feel appropriate for your
application.
If that's not auitable, to answer your original question :-) is Option 3:
I think the session files consist of a series of variable names and
serialized values separated by semi-colons or something like that.
So to read/write the session files would be something not unlike:
$data = file($session_file);
$elements = explode(';', $data);
while (list(, $element) = each($elements)){
list($var, $serialized) = explode(':', $element);
$$var = unserialize($serialized);

RE: [PHP] Re: mediator between PHP and Perl (with sessions)
Eli, Sessions work just fine with CLI (Command Line Interpreter), although there is little need for them as a CLI script, since once started the script does not wait on user clicks of a browser for it's next set of input, therefore no need to use sessions for passing information. Most CLI scripts are started via a cron process, and if started from a webpage, the items passed to the script can be passed via command line parameters, or if passed as session variables, the session key needs to be passed to the CLI script, since CLI scripts don't have access to cookies. One advantage of using session variables when starting a CLI script, is that the session may be able to pass bigger values than can be contained in a command line. (Command line variables can be accessed in the argc/argv array like in c) and once passed this way the sessions are no longer needed since your CLI script will run to completion. If your server is a NIX box, you may have access to the character after the command name that will cause it to run as a separate shell script, but you will need to set the timeout to allow it to run long enough, and if you do not use the separate shell character, the script will be interruptible by the user who started it by clicking a button like stop on his browser. The unserialize function is indeed used for sessions, but with most newer releases of PHP register variables is turned off, which means the variables are not restored automatically (you will find them in the $_SESSION array). Sections of the manual you may want to reread are as follows; http://www.php.net/manual/en/ref.session.php http://www.php.net/manual/en/function.session-set-save-handler.php (good illustrations of what happens in sessions) http://www.php.net/manual/en/function.session-register.php (notice the notes on register variables). http://www.php.net/manual/en/function.session-id.php http://us3.php.net/manual/en/function.set-time-limit.php to allow script to run longer. http://us3.php.net/manual/en/function.shell-exec.php for starting a cli script (don't forget to start php). hope this helps, Warren Vail -Original Message- From: Eli [mailto:[EMAIL PROTECTED] Sent: Tuesday, February 15, 2005 7:07 AM To: php-general@lists.php.net Subject: [PHP] Re: mediator between PHP and Perl (with sessions) It's quite easy to pass the session variables to the script.

Re: [PHP] Delete a file immediately after download
Shaun wrote:
Thanks for the reply, I know how to delete a file I just wanted to know if
its possible to ensure that its deleted automatically as soon as the user
has downloaded it.
Yes.
You don't even put the file into your web tree DocumentRoot directory, and
you write a PHP script that allows the user to view it.
Something like this:
?php
$path = /path/to/some/directory/not/in/the/web/tree/;
$filename = isset($_REQUEST['filename']) ? $_REQUEST['filename'] : die();
//Use this to be damn sure they don't go after /etc/passwd or ../secret
or...
$filename = preg_replace('/[^A-Za-z0-9_-]/', '', $filename);
//Allow for the possibility of the file not being read correctly, and
//only delete it if your hardware behaves.
if (readfile($path$filename)){
unlink($path$filename);
}
?
The only thing is, though, that if the user aborts halfway through their
download, or their network connection flakes out, or, for that matter,
*YOUR* network connection dies on the server, or...
There are a lot of reasons why the file could end up not ACTUALLY being
delivered to the browser, but you'd still delete it.
If the user can just do over whatever they did to get the file, that's
no big deal.
If this is something where they paid money for it, but you delete the file
before they REALLY successfully get it, that's a bit more of a problem.
In that case, you might be better off to warn the user the file will be
available for download only for 72 hours, and record a time-stamp in the
db with each filename when it gets created, and then run a cron job that
unlink's anything from the db older than 72 hours.
Which you might want to do ANYWAY to get rid of files that some goofball
user never bothers to download, or the readfile actually does fail (rare,
but possible) or they cancel the connection and your script quits halfway
through the readfile or...

getting
is a bunch of weird characters.
Those weird characters ARE the image.
Most likely, you finally got it right, and got rid of all the error
messages, and now your image is PERFECT.
However, when you have the errors in it, PHP sent out a Cotnent-type:
text/html header before the error messages -- so you could see them as
text error messages, which they were.
At that time, Internet Explorer *CACHED* those headers, and is now
thoroughly convinced that the URL *is* text/html, even though you are no
longer sending that header. So IE is going to keep showing you the
document as text/html, because IE is really stupid.
If you quit IE, and start up again, and surf to the image, it should all
just work.
Oh, and don't do:
echo ImagePNG($im);
Just to:
ImagePNG($im);
The imageXYZ functions print out the image already, and then return 0 or
-1 or something based on their success/failure to print the image.
The way it works out, you're actually dumping out the image and then some
bogus data at the end -- because the ImagePNG gets called FIRST, which
prints out the image, and then your echo prints out the return value after
all the image data went out.
Most browsers probably gonna ignore that bogus extra data at the end of
the image.
You might want to add some error checking to your code.
And use imagecreatetruecolor() to make a cleaner pie internally, even
though you are converting to PNG in the end.
Here's my code:
function makepie($slice, $total){
$height = 150;
$width = 150;
$im = ImageCreate($width, $height);
$bck = ImageColorAllocate($im, 255,255,255);
$black = ImageColorAllocate($im, 0, 0, 0);
$red = ImageColorAllocate($im, 255, 0, 0);
imagefilledellipse($im, 75, 75, 125, 125, $red);
imageellipse($im, 75, 75, 125, 125, $black);

$pieslice = (($slice / $total) * 360) + 315;

IMG_ARC_PIE);
//Return

echo ImagePNG($im);
}

Plus taking out ! in the first one. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

For the first 20 only the Next link would show and whenever the last set would show only the Previous link would. Every other time both would show.

Im pretty sure the double backslash is a typo.
No, it's *NOT* a typo.
Inside of apostrophes, \ *IS* a special character.
It's also special inside of quotes, but let's stick with apostrophes for now.
\ is used to escape an apostrophe inside of apostrophes.
So you can do:
$var = 'Don\'t forget to escape apostrophes!';
Because \ is used to escape the apostrophe, you also use it to escape the
backslash itself:
$var = 'Backslash \\ should also be escaped';
Inside apostrophes, those are the ONLY two special cases:
\' turns into apostrophe: '
\\ turns into backslash:\
Inside quotes, you've got a bunch more like \n, \r, \t as well as variable
substitution going on.
Now, because ONLY those two special cases exist, you *CAN* type:
$var = '\d';
and PHP will store internally: \d
because the backslash wasn't followed by ' or \, so it must be just a
literal backslash.
But that doesn't make it Good Style.
In my *opinion* one should use:
$var = '\\d';
so that it is completely clear that the backslash is being escpaed, and
you're not trying to get a control-D (end of file) or whatever.
Or, put it this way:
It's incredibly unlikely that PHP will ever change '\d' to mean control-D.
But it'e even MORE unlikely that PHP would change '\\d' to mean anything
other than:\d
The same sort of paradigm is true for quote marks -- You *CAN* get away
with a single \ inside of quotes, so long as it's not followed by:
n
r
t
$
x[0-9A-Fa-f]{1,2} (a Hex number with \x in front)
[0-7]{1,3} (an Octal number with \ in front)
But with *THAT* many possible following characters, people have gotten
more in the habit of using \\ inside quotes.
But PHP is consistent with *BOTH* apostrophes and quotes about the \
character: There are always a limited number of character combinations
that can follow \ to give it special meaning. Any other character
combination following \ just uses \ literally.
\d always turns into \d inside quotes or apostrophes.
\a always turns into \a
\b turns into \b
.
.
.
ONLY \, \n, \r, \t, etc (see above) turn into something else inside quotes.
ONLY \' and \\ turn into something else inside apostrophes.
To be CLEAR in your code, however, I highly recommend using \\ in ALL
strings when you want a literal backslash -- so that there is no question
whether you are trying to escape the next character as something special,
or you just want a backslash.
\\ *always* means a single backslash
\ sometimes means a single backslash, and sometimes means something
entirely different depending on what follows it.
Use \\, so you *always* know what is going on.
well you have to escape the bslash if your using double quotes.
there is a reason sane people (normally) write regexps in php
using single quotes :-)
Unless your regex contains apostrophes a lot, and then quotes are easier. :-)
//Bad Example: (strstr would be better choice here)
$contraction = ereg(', $word);
I'm sure others will disagree with me, but this is my opinion on writing
clear code with \ inside of apostrophes and quotes:
Always use \\ to get a literal backslash, and you'll never get confused,
because \\ always means one (1) backslash.

It adds up to about 250KB in the actual session file -- that is, the serialized data. I'm not clear of the impact this will have in performance when it's in a multi-user environment, and I'm not sure at what point the overhead Throw an ab (Apache Benchmark) test at it and find out. Don't just guess or sit there wondering. You could run test in about the time it took to compose this email -- certainly as fast as the total man-hours put in by all of us reading/discussing it on the list :-) of serializing and unserializing gets to be more than the overhead of sticking this stuff in a temporary database table and then retrieving it. Serializing is simpler but my git says there has to be a point at which it gets inefficient. Testing is complex since I would have to write all the database code in order to do any performance measurement. Actually... All the database code is already written for you on the PHP web-site, and it's about one 8.5x11 page of five (5) functions. Doesn't really sound like a complex test to me. Even if it *IS* a lot to do... The database connection is going to dwarf the rest of it, almost for sure, so just time how long it takes to open up a database connection, compared to loading your existing file-based sessions. Sending the actual query and getting/storing the results will be chump-change compared to opening the db connection, almost for sure. *UNLESS* every page that needs session data already *HAS* a db connection. At which point you are comparing: Hard drive access, with hard drive cache and page faults Database access, with database buffers These two will be neck-and-neck on performance, and will depend more on your hardware than on somebody else's experience with their hardware. Particularly if you've got a 2-tier setup with database on one box and PHP on another, where your network hardware and cabling gets involved. Anyone have relevant experience in this area, and/or some educated guesses? You can minimize the data storage requirements by using short variable names and casting your numeric values to integers when possible. PHP sessions store everything as strings unless you specify otherwise. For example, here is the integer 123 stored in a session both ways, as a string and cast to an integer: v|s:3:123; v|i:123; There are other things too.. like converting IP addresses to longs with ip2long(). Storing a long int is more efficient than storing 7-15 bytes of character data. Just look at your session data and see what can be stored smaller, variable names included. [shudder] If you have to choose between a meaningful variable name and performance considerations, buy more hardware! :-) The cost you'll save in the long run for code maintenance will make it worth it. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

If physical security of the box is an issue then overwriting the file with random data and then unlinking it might be a decent solution. If a file is opened for writing I suspect it depends on the operating system as to whether the same disk blocks are used so overwriting a file might not actually over write the data on the disk. It should, however at least change the directory entry enough that someone with access to the box will not be able to use a simple undelete utility to retrieve the file.

[PHP] issue with accents and mysql
Hello,
please help me on the following issue.
please reply to [EMAIL PROTECTED] too.
(I asked for help on the php-db ml, but nobody replied)
I have hacked the following function:
function accents($text) {
global $export;
$search = array ( 'à', 'è', 'ì', 'ò' , 'ù');
$replace = array ( '\\`{a}', '\\`{e}', '\\`{i}', '\\`{o}', '\\`{u}');
$export= str_replace($search, $replace, $text);
return $export;
}
It works fine, as long as I feed it with a string:
accents('à') -- \`{a}
The issue is when I get 'à' from a mysql table.
I.e., for some record of a mysql table Table, let à the value of the
field Field, and say
$result = mysql_fetch_array($answer, MYSQL_BOTH),
where $answer= mysql_query(SELECT * FROM Table).
Now accents($result['Field']) returns à (instead of \`{a}).
Why? I have no idea.
Any hint is welcome.
Thanks a lot

[PHP] Intelligent Forms and Form Processing
Hello, all -
I am working on a few small projects to try and teach myself how to
build intelligent forms. I have come as far as making a few simple ones
that are created when their parent function is called. Something like
the following:
function displayMyForm($username='',$password='',$account='') {
// do some stuff for the vars that were passed
// create form
}
Nothing much, but it gives me a good footing on the use of displaying
forms dynamically even when some data is missing - making use of default
values.
The problem that I am faced with now, as simple as it seems, is a
situation such as the following:
User goes to index.php, enters in some information. ACTION='? echo
$_SERVER['PHP_SELF'] ?' is the action. Some data is carried in the
form of variables that were entered in on a form.
I want that same page to catch that data and process it. If the data
is complete and valid, pass to another section of the form. If it is
not, prompt the user to re-enter some data.
I don't really know what I'm asking here. I guess ultimately I'm
curious as to how people make intelligent forms such as this. How do
you deal with missing/incomplete values? What about multiple steps of
a form? How do you verify that, if a user is on step 2, they came
from step 1? Do you mix $_GET and $_POST to verify the process?
Not coming from a big programming background, some people might think
that these questions are pretty lame, and I'll go ahead and tell you
that you are absolutely correct. However, as I start, I would like to
develope and work on good programming habits, so I don't learn bad
habits to begin with.
Any feedback will be appreciated.
Thanks

Chris.
that's a different issue.
There are always at least 2 things you should do with your (expected) input:
1 - check if it *exists* (isset)
2 - check the validity (input-validation)
for step #2 empty is very commonly used, and also a very useful
function. However, you should never do #2 without #1, since that again
raises issues (of security, problems, unexpected input, etc)
Also note that empty($non_existent_var) will always throw an E_NOTICE
error when the variable in question is not set. isset() is the only
function/language-construct that can check for the existence of
variables without throwing an E_NOTICE.

You can muck around with CSV if you prefer, but tab-delimited is way
easier, assuming no tabs in your content.
This also assumes no newlines in your content.
If there are tabs and/or newlines in your content, you can use MySQL's
replace function (not the REPLACE INTO, but the string function 'replace')
to change tab to, err, \\t or something, and newline to Mac
carriage-return or something.
You'd have to do this (and more) to get CSV working right.
The on-line manual has example code for CSV at http://php.net/fputcsv
Maybe you should have googled before posting, eh?

http://pear.php.net/package/Html_quickform
To the people who want to truly understand how the system works, the
wheel, as it stands, is wothless :)
I know I can use a drop-in solution, and I might consider it in the
future. However, if I understood in more detail the entire process, I
would be able to troubleshoot and add advanced features to the wheel.
That's how I look at it, anyway.
I like the attitude from a learning standpoint but since you asked for
feedback you could have at least acknowledged the guys effort in offerin
one solution.
This thread is very similar to another one today. and the answer is the
same. use some sort of conditional construct to determine how you are
being requested and process accordingly.
I usually set a hidden variable that can be checked to let me know what
to do.
if (isset($_POST[myvar] $_POST[myvar] = expected value){
# perform second phase form
}
else {
#do form phase one stuff.
print input type=hidden name=myvar value='expected value'\n;
}
one of many ways to do it. I have to say I have done quite a bit of
this sort of thing and it gets really confusing to maintain if there is
a lot of logic involved.
One one hand it is nice to know you only have to change one file if a
change is needed ( especially if there are changes to the parameters
being passed from the entry side to the processing side. I have yet to
feel strongly one way or the other whether it is better to use a single
file or multiples.

Hello,
please help me on the following issue.
please reply to [EMAIL PROTECTED] too.
(I asked for help on the php-db ml, but nobody replied)
I have hacked the following function:
function accents($text) {
global $export;
$search = array ( 'à', 'è', 'ì', 'ò' , 'ù');
$replace = array ( '\\`{a}', '\\`{e}', '\\`{i}', '\\`{o}', '\\`{u}');
$export= str_replace($search, $replace, $text);
return $export;
}
It works fine, as long as I feed it with a string:
accents('à') -- \`{a}
The issue is when I get 'à' from a mysql table.
I.e., for some record of a mysql table Table, let à the value of the
field Field, and say
$result = mysql_fetch_array($answer, MYSQL_BOTH),
where $answer= mysql_query(SELECT * FROM Table).
Now accents($result['Field']) returns à (instead of \`{a}).
Why? I have no idea.
Any hint is welcome.
Thanks a lot
I have no idea what might be the problem but I would probably start by
seeing what the difference is at the ascii level.
preg_split the strings and run ord on each one
foreach ( preg_split(//,this is a string) as $char ) {
echo The ascii value for $char is . ord($char) . \n;
}
post the results from both sources and lets see what can be found.

[PHP] function to remove all \ from a variable
Hello,
I'm using FCKeditor to edit content on my site.
But the content it produces escapes all the (double quote) characters
from my HTML, and replaces it with \ (backslash-double quote).
Is the a function that I can use to change it back?
Does str_replace() do it.. if so is this how I use it:
str_replace('\', '', $_POST['FCKeditor1']);

Sorry for clogging up you mail box.
Yes.. str_replace('\', '', $_POST['FCKeditor1']) works.
I must've needed to think through my thoughts by typing it out.

Hi What you can do is change the php.ini file In the [session] section like this: session.use_cookies = 0 session.use_only_cookies = 0 session.auto_start = 0 and now make sure that all script are running under the same session id at the beginning of each php script you should add the following lines : session_id(0f516a62cf2bab6f867dda9320358b6d); session_start(); hope I've helped Yaron Khazai -Original Message- From: Eli [mailto:[EMAIL PROTECTED] Sent: Tuesday, February 15, 2005 10:09 AM To: php-general@lists.php.net Subject: [PHP] mediator between PHP and Perl (with sessions) Hi... I got a shared lib API written in PHP, that depends on sessions for its operation. I took a prepared system in Perl that I want integrate with the shared lib API in PHP. What I thought about is, to write a mediator class in Perl that will define the same API functions as I got in the shared lib API in PHP. I do not want to imitate the API functions workflow in Perl, but instead call the shared lib API in PHP from Perl (this way I don't have to maintain 2 class APIs in different languages). I thought of making a PHP script that can run on shell and return serialized output of any API function in the shared lib. Then call that script from Perl and process the returned output in Perl. Problem in this way is, that the shared lib in PHP uses sessions which are un-accessable from a shell script. And I cannot put that script on the web, since it returns sensitive data. Is there a way to use sessions variables in PHP shell script (without reading the session file and parse it in the script)? If anyone is familiar with any other implementation of such a mediator, please tell. -thanks, Eli. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Re: isset
On Tue, 2005-02-15 at 16:22, M. Sokolewicz wrote: Chris. that's a different issue. There are always at least 2 things you should do with your (expected) input: 1 - check if it *exists* (isset) 2 - check the validity (input-validation) for step #2 empty is very commonly used, and also a very useful function. However, you should never do #2 without #1, since that again raises issues (of security, problems, unexpected input, etc) Also note that empty($non_existent_var) will always throw an E_NOTICE error when the variable in question is not set. isset() is the only function/language-construct that can check for the existence of variables without throwing an E_NOTICE. This is not true and explicitly states so in the doc. I had to reread it to remember why I stopped using it. empty will return true if the value is one of several things , 0, 0 to name a few. Since I do not consider these empty I stick with isset and then test for a valid value depending on the circumstance. Personally, I think people piss and moan too much about what I consider proper coding practices. Input validation is to important to skimp on. Again it is my opinion. I have been revisiting some php code that I wrote a couple of years ago and have been pleasantly surprised at the job I did on input validation. A similar complaint occurs when installing a new version of or moving code to another box where register_globals is not on. I pissed and moaned and wailed for about 10 minutes until I thought about it and can now see the value in not having unknown variables pollute the namespace. Of course, since most of my code was already validating the variables, a few :s/\$\(var\)/\$_GET[\1]/ iterations and I was good to go. Yes it took some time but I feel better having done it. I just wish there was a use strict; sort of deal so I would not have to hunt down logic errors due to mistyping a variable name.

Re: [PHP] Session Vars and Performance

You could run test in about the time it took to compose this email -- Perhaps if you are already familiar with ab, which I'm not ... and if the server supports it, which it does not at this moment, development is on Windows, later testing and deployment on Linux. All the database code is already written for you on the PHP web-site, and it's about one 8.5x11 page of five (5) functions. Doesn't really sound like a complex test to me. The data is an internal list of items on the form, all the form field specs, the data for the fields, default data for resetting the form, and a data structure for the forms class. Most of these are in associative arrays, sometimes nested a couple of levels deep. If I'm going to build a database structure that mirrors the array structure, and update it every time the array changes during development, that's hardly straightforward. Without that, I'll have to serialize and unserialize the data -- and if I'm going to do that, I'd guess that I might as well use the session vars. So maybe that answers the question, and the remainder (below) is theoretical. Sending the actual query and getting/storing the results will be chump-change compared to opening the db connection, almost for sure. I do actually need a DB connection on every page anyway, so there's no benefit to avoiding one for this purpose. But to me the likely consumer of cycles here with a database structure matching the data structure would be the conversion of MySQL data into an associative array, and I'd be comparing that to serializing and unserializing. I don't think either is going to be trivial. These two will be neck-and-neck on performance, and will depend more on your hardware than on somebody else's experience with their hardware. Fair point. Particularly if you've got a 2-tier setup with database on one box and PHP on another, where your network hardware and cabling gets involved. Not in this case. If you have to choose between a meaningful variable name and performance considerations, buy more hardware! :-) Agreed!

Comments in the code make using short session variable names a non-issue. Most of what's in my session file is data, not variable names, and my variable names are not particularly long. Descriptive, but not overly so (actually in this case most of the 'names' are associative array indices). If I shortened the variable names I might go down from 250K to 200K -- if that -- at a large cost in time for code modifications. I'm not at all keen on that approach, though I'm sure it might work for some. -- Tom -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] other mhash hashes
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1
I thought some other people would be interested in the other hashes
that you can do with mhash that aren't on the php.net docs after the
recent news that SHA-1 might be weaker than previously thought:
http://www.schneier.com/blog/archives/2005/02/sha1_broken.html
The built in constants that the mhash docs have listed are simply
integers that tell mhash what to use. So I found the integers in
mhash's mhash.h:
http://cvs.sourceforge.net/viewcvs.py/mhash/mhash/lib/mhash.h?rev=1.25view=auto
The following works for alternate hashes in the Win32 PHP 5.0.3
release of libmhash.h. For anyone wanting a step up from SHA-1, SHA256
works.
$hashes = array('CRC32' = 0,
~ 'CRC32B' = 9,
~ 'ADLER32' = 18,
~ 'MD4' = 16,
~ 'MD5' = 1,
~ 'RIPEMD160' = 5,
~ 'SHA1' = 2,
~ 'SHA256' = 17,
~ 'HAVAL128' = 13,
~ 'HAVAL160' = 12,
~ 'HAVAL192' = 11,
~ 'HAVAL224' = 10,
~ 'HAVAL256' = 3,
~ 'TIGER128' = 14,
~ 'TIGER160' = 15,
~ 'TIGER192' = 7,
~ 'GOST' = 8);
foreach($hashes as $name = $number) {
~echo 'br /';
~echo $name, ': ', bin2hex(mhash($number, 'this is a test'));
}
or as PHP constants:
$hashes = array('CRC32' = MHASH_CRC32,
~ 'CRC32B' = MHASH_CRC32B,
~ 'ADLER32' = MHASH_ADLER32,
~ 'MD4' = MHASH_MD4,
~ 'MD5' = MHASH_MD5,
~ 'RIPEMD160' = MHASH_RIPEMD160,
~ 'SHA1' = MHASH_SHA1,
~ 'SHA256' = MHASH_SHA256,
~ 'HAVAL128' = MHASH_HAVAL128,
~ 'HAVAL160' = MHASH_HAVAL160,
~ 'HAVAL192' = MHASH_HAVAL192,
~ 'HAVAL224' = MHASH_HAVAL224,
~ 'HAVAL256' = MHASH_HAVAL256,
~ 'TIGER128' = MHASH_TIGER128,
~ 'TIGER160' = MHASH_TIGER160,
~ 'TIGER192' = MHASH_HAVAL192,
~ 'GOST' = MHASH_GOST);
foreach($hashes as $name = $number) {
~echo 'br /';
~echo $name, ': ', bin2hex(mhash($number, 'this is a test'));
}
I suspect if you were able to compile a more recent version of mhash,
the following complete list of mhash's hashes would work, including
SHA512 and WHIRLPOOL.
$hashes = array('CRC32' = 0,
~ 'CRC32B' = 9,
~ 'ADLER32' = 18,
~ 'MD2' = 27,
~ 'MD4' = 16,
~ 'MD5' = 1,
~ 'RIPEMD160' = 5,
~ 'RIPEMD128' = 22,
~ 'RIPEMD256' = 23,
~ 'RIPEMD320' = 24,
~ 'SHA1' = 2,
~ 'SHA224' = 19,
~ 'SHA256' = 17,
~ 'SHA384' = 21,
~ 'SHA512' = 20,
~ 'HAVAL128' = 13,
~ 'HAVAL160' = 12,
~ 'HAVAL192' = 11,
~ 'HAVAL224' = 10,
~ 'HAVAL256' = 3,
