[PHP] preg_replace wierdness
Code snippet ->
header('Content-type: text/plain');
$foo = ' ';
echo "$foo\n";
$path = '../../../';
$bar = preg_replace('/()/', "$1" . $path . "$2", $foo);
echo $bar;
?>
The second image doesn't get affected by preg_replace(). But if I break
$foo into multiple lines like ->
$foo = '
';
It works...
Any tips would be appreciated...
Thanks

[PHP] Logging out and session ids
I was just going through the archive. Seems this comes up enough for me
to think I have something wrong.
A simplistic code flow of events...
session_start();
// user successfully logs in, set a session variable
$_SESSION['user_id'];
// when the user logs out, destroy session and redirect to top
$_SESSION = array();
setcookie(session_name(), '', time() - 3600);
session_destroy();
header('location: back_to_top');
?>
Ok, so when the user logs in, a session id is assigned to them.
When they log out and are redirected to the beginning, the session id is
the same (verified by the file name in /tmp and cookie manager in mozilla).
My question is, even though the session contains no data after its
destroyed, should the session id remain the same, after logging out,
or should another be assigned when session_start() is called after the
redirect???
Thanks

The browser will send the old cookie and as the name is probably the same as the
the old session it will get used again, or at least I think that is what is
happening :)
This should not be a problem as the data associated with the old session is
gone.
If that is the case, then the setcookie() call to destroy the clien't
cookie probably isn't neccessary.
If you close the browser and start a fresh one you will get a new session id.

[PHP] Sessions not written to db on windows...
I have a bit of code that uses sessions and stores session data in the
database.
Works flawlessly on FreeBSD 4.7/mySQL/PostgreSQL running php 4.2.3.
When trying to run my code on Windows 2k with MSSQL and mySQL, its not
working.
The windows box is running php 4.1.2 (its a dev box).
Here is the section on sessions from php.ini.
Can anyone see anything wrong with this setup??
And also, can alternative means of storage be used under windows php??
Thanks for any insight you may provide...

[PHP] How to handle "so called" expired sessions??

Say I log into the site, and the session is started, and I don't do anything for the next 30 mins, then go back to the site.

Re: [PHP] How to handle "so called" expired sessions??
I was the original poster to this topic. Quite suprised it continued.. I have my sessions stored in a database, thus I thought the problem was there, but have come to realise, that is how sessions behave naturally. I originally thought, that the expired session garbage collection dumps stale sessions, if the user is away after the default 24 minutes. But in my case, it does, but since the user still has a valid session cookie containing valid data, the session is brought back from the dead even if hours has passed, and the browser hasn't closed. Not desirable for me. As Tom pointed out to me, (which I haven't gotten around to do as yet) in not so many words -> 1. When the user logs in assign a session variable to lets say time() + 600 (10 mins in the future). 2. Each page load, refresh the session variable in step 1 *if* the session variable references a future timestamp. 3. If on a page load, the session variable references a past (older than time() - 600) timestamp, core dump the session data -> $_SESSION = array(); to /dev/null, hell, whatever makes you happy... Although I haven't gotten around to using these steps, it seems like it would work for what Im trying to achieve. John W. Holmes wrote: No question :) It's just that this is what the original question was about and why I suggested doing his own sesssion timeout check as the deleting proccess is too unreliable to depend on for timeout handling. PHP will quite happily return stale data which could be bad in a login type of situation. Okay. I think I thought you were the original poster. How do you know it's returning "stale" data, though? If the cookie is valid, and there is still a session file (or data in memory), then why is it stale or expired. Maybe I'm just missing something here. If it's expired because you think it's too old, then you track your own timestamps and do your own cleanup. Is that what you're saying? ---John Holmes... -- Gerard Samuel http://www.trini0.org:81/ http://dev.trini0.org:81/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Reject some?
What Im trying to do is, reject all email address strings ending in
yahoo.com, except [EMAIL PROTECTED]
Im trying ->
if (preg_match('/[^[EMAIL PROTECTED]|yahoo.com]$/', '[EMAIL PROTECTED]'))
{
echo 'match found';
}
else
{
echo 'match not found';
}
?>
The search pattern must also be capable of expanding to something like ->
^[EMAIL PROTECTED]|yahoo.com|^foo@hotmail|hotmail.com
Basically what Im trying to perform is to reject all email address
strings ending in either yahoo.com or hotmail.com,
except strings ending in [EMAIL PROTECTED] or [EMAIL PROTECTED]

Re: [PHP] Sessions and AOL
No its not a matter of tying a session to an ip address. Im modifiying some code that works as a "whosonline" on a site at any given time. Currently, it mainly works off ip address, of which we all know isn't accurate. As far as my usage of the word "AOL", that only represents my personal experience, with the ip address jumping phenomena.

[PHP] stripslashes and quoted material
Hey all. I noticed a string containing slashes was breaking some code
of mine on an w2k/IIS box running php 4.2.3.
For example ->
http://www.apache.org/\"; target=\"_blank\">
When trying to apply stripslashes, the slashes remained. So I applied
str_replace('\"', '', $var) and that worked.
Any idea as to why stripslashes would not remove the slashes in the string?

All is well with stripslashes() again.

stripslashes() will unescape single-quotes if magic_quotes_runtime = Off
in your php.ini. If you have magic_quotes_runtime = On, then it will also
unescape double-quotes (and backslashes and NULLs).

Re: [PHP] Is it possible to test an uploaded file to check the type?
The upload process, already collects info on file types when you upload. From the manual -> $_FILES['userfile']['type'] The mime type of the file, if the browser provided this information. An example would be "image/gif". So, check $_FILES['userfile']['type'] against a set of allowed file types, and you're set...

[PHP] BigEndian to integer
A bit off topic Im trying to figure out how to convert BigEndian byte words to integers. For example -> 0 0 0 18 = 18 The only way I know how to convert this is by writing down on paper, and writing 8 4 2 1 above the numbers and adding up the values. Trying to figure out a way via plain old math/php has me stumped at the moment. (Maybe some sleep is in order) Any help and or tips would be greatly appreciated.

Re: [PHP] Is it possible to test an uploaded file to check the type?
Thank you for your reply. A little background on what Im doing with file uploading. 1. Im allowing registered users to upload avatars for their own usage. 2. Im allowing image uploading for submitted articles by certain registered users. 3. And Im currently constructing a media gallery, where images, mp3, realaudio, etc can be presented/downloaded/streamed. All 3 points are based on a file upload class that I put together. Of which each section has their own allowed set of mime-types, based on what is supplied via $_FILES['xxx']['type'] An analogy that I have in mind is this. Lets look at the file upload class as the Post Office. They practically allow any package to be delivered to anyone by anyone. They do scrutiny checks on packages. Unfortunately, this one package, has a pipe bomb in it. Its delivered to my mailbox, and poses a threat. Now, is it the fault of the PostOffice for allowing that particular package through? What else can this PostOffice do to tighten things up? So Im at the point, where Im trying to figure out what else I can do to "tighten" scrutiny checks. Concerning infecting the server, if the files are chmodded without the executable bit, shouldn't that be considered *safer* It may seem that mime_content_type() isnt an option. I tried it on a flash file, and it reported it as text/plain. What would really be cool, is a php extension to a virus scanner.

If, for instance, the only person who will be downloading or handling the file will be the person who uploaded it, everything should be fine. (NObody's going to infect / r00t their own computer intentionally). But let's say you run the file yourself. In that case, that file can hurt your server.

[PHP] Securing File Uploads Was: Is it possible to test an uploaded fileto check the type?
Sorry for bring this back to life, but Im looking for some more opinions. A friend and I are somewhat dead locked, as to whether with available tools via php, that its possible to *reliably* secure file uploads. File uploads currently encompass, images, mp3, real audio files, with plans for ogg vorbis, flash, and what ever audio/visual/document file formats, I can make php read its metadata. These files will be used in a gallery type environment, to be displayed, downloaded, or streamed. The end product will be used by people who most likely will have their sites hosted, thus no real control over the server, and can be run on *nix/Windows environments. Browsers that I've tested with: IE 6, Mozilla 1.4(Windows/FreeBSD), Opera 6(FreeBSD) Spoofed file in question: Renamed putty.exe to putty.mp3 Side Note: Image uploading can be more or less be considered secure because Im running it throught getimagesize() which will report false on non image files. Currently, the upload process, checks the browser reported mime type against a predefined set of mime types. The file extention is checked against a set of predefined file extentions. Then the file is moved to its final destination, and is read for its sequence of magic bytes for its metadata (which depends on the file's extention, so it knows what to look for). Files are stored in a predefined directory under the webroot. With IE6, the upload fails because it correctly reported putty.mp3's mime type as not being an mp3 file. With the other browsers in question, they solely report the mime types according to the file's extention, so the file is successfully uploaded. Now remember, that the target audience for the script will most likely be on a shared host, thus no control over the server. Is there anything else I can do using php, that can help in making the process more secure??? mime_content_type() isn't an option, as it doesn't report all mime types. Reversing the order of reading the file's, magic bytes, and storing it, doesn't really improve matters, as it depends on a file's extention.

[PHP] Making a PHP Script "Very" Cache Friendly
Searching through the archives, most people are running away from
caching php scripts.
Im trying to do the opposite.
I have a script that fetches css files. Im trying to add header() calls
to it so
that browsers can cache it like a normal css file.
This is what I have at the top of the file ->
--
header('Content-type: text/css');
header('Expires: ' . gmdate('D, d M Y H:i:s', time() + 3600) . ' GMT');
header('Last-Modified: ' . gmdate('D, d M Y H:i:s',
filemtime('./foo.php')) . ' GMT');
For the life of me, according to the output of ethereal (a network
sniffer), this file is always fetched from the server.
Yes I did breeze by the HTTP 1.1 spec, but I didn't pick up on anything
special that I should be doing.
Is there a way to make the file be put into cache, or am I barking up
the wrong tree.
Thanks for your insight.

Ok, I think it has been working all along.
Someone asked if I was viewing the actual headers. Yes I am, using
ethereal.
During my previous tests, I was reloading the page, which caused the
dynamic css file to regenerate output, while the other
css files send a "304". If I were to click on a link normally, the
dynamic file doens't show up in the header stream, so Im
assuming that means its cached. Someone else suggested that I add
header('Cache-Control: max-age=3600');
Ill do that as its the http 1.1 version of expire. Its not going to
hurt anything.

[PHP] When to escape slashes, and when not to???
I have a class method that does one thing and one thing only.
Escape characters before going to the DB.
Part of it is ->
if (!get_magic_quotes_gpc())
{
$string = pg_escape_string( $string );
}
return "'" . $string . "'";
In everyday get/post operation it seems to work flawlessly.
I've come across a situation where Im parsing an XML file to insert into
the DB.
The content needed to be escaped, so I modified the above to ->
if (!get_magic_quotes_gpc() || !get_magic_quotes_runtime())
{
$string = pg_escape_string( $string );
}
return "'" . $string . "'";
And the XML data is escaped correctly for DB insertion.
Now going back to my everyday get/post operation, the code is broken
somehow, as content,
that is not normally escaped is escaped, and breaking stuff, like
serialized data in the DB.
Is the above code valid for escaping characters in get/post/cookie and
external data operation?
Can they be safetly used together as in my example above. (Where if one
condition doesn't meet, and the other does, escape characters).
Or there may be something else in my code that is messing things up.

Re: [PHP] PHPSESSID appended to URL on initial page load
Actually, over the weekend, I started using sessions in my scripts.
All I did was start it using session_start();
I only noticed this behaviour using Opera 6.02 Linux browser running
under FBSD 4.6-Stable.
(It may have happened in mozilla 1.0 r3, but I may have not paid
attention to it).
I load the page the first time and the PHPSESSID is appended to the url.
All links on the pages has the same appended SID. Then a reload clears
it away.
I thought it was something in my code since Im not too familiar on
session usage.
Im running php 4.2.2 on FBSD 4.6.2-Release.
Thx

[PHP] unlink() and IIS
Im running a dev box with IIS 5/Apache/php 4.1.2
I just noticed that part of a script that is supposed to delete a file
isn't working under IIS but is under Apache.
Under IIS, php is installed as isapi.
Paths are correct, and the file in question is created by the script and
according to the permissions, SYSTEM has full access to the file.
MARC and user notes under unlink() didn't reveal anything about why
unlink() works for some and not for others.
Code snippet in question ->
--
$log = '../../includes/error/error.log';
if (isset( $_POST['Reset'] ))
{
if (!unlink($log))
{
trigger_error('UNABLETORESETLOGFILE' , E_USER_WARNING );
}
}
Can anyone shed any light for me.
Thanks for any insight you may provide.

It seems to work well with words like "this" and "don't" but it doens't
work with words with accents to it like

Could my regex be expanded to handle non-english type characters, or any
workarounds to get a string into an array of words,

[PHP] My 2cents on xml/php
This is not meant to put down the php/xml combo. Just putting down my 2 cents from my experience thus far, into the archive for anyone else looking for info. I just started getting deep into parsing xml yesterday, and the dust has just begun to settle. Im parsing rss files versions 0.91 - 2.0 just for content. Before, I was using a class from phpheaven.net, phpsyndication, which basically is using regex to scan/grab content from an rss file. On my PIII 450 dev box running FBSD 4.7, there is a noticeable hit using php's xml functions to parse the rss file. Using siege, http://www.joedog.org/siege/index.shtml, I did some before and after tests. Im experiencing on average a 9-14% drop in number of requests my script can handle. And for some reason, the percentage drop is a bit larger when parsing rss 2.0 files. (Maybe my code). But I going to accept this, and Im going to keep my new code. I have plans to use caching in my script at a later date, so its not going to be too bad. So xml may have some advantages, but in my opinion, if you're going to use it extensively in your scripts, consider caching its final destination, because, using php xml functions to parse xml is going to add overhead to your script. Thats my 2 cents... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Socket Connections Was: Re: [PHP] Resource type numbers
Ok, I think I found out why the script Im debbugging is returning an empty string. 1. It opens a socket to the mailserver with fsockopen 2. It checks the greeting by reading using fgets() 3. Then it check the reponse by supplying the username to the fsockopen() connection 4. It returns an empty string. It seems as if the first time fgets() was used on the open connection, it reads it to EOF. Any further attemps would fail because the data from the socket connection is at EOF. I tried to rewind() it, but rewind() doens't take socket resource. So, going by what this script is trying to do, (I have no experience with this), is it correct to assume, that with each attempt to talk to the server, a new connection must be made to read data from it??

error_display($msg);
break;
default:
return;
}
$date = date('D, M d Y H:i:s');
$msg = sprintf("[%s]: %s in %s on line %d\n", $date, $msg, $file,
$line);
$test = error_log($msg, 3, './error/error.log');
if ($exit === TRUE) exit;
}
When I trigger and error with E_USER_ERROR, it executes error_display()
but it continues to display the rest of the content for the page.
I thought E_USER_ERROR stops execution of the script.
Thanks for any input.

[PHP] PEAR Benchmark & other benchmark techniques??
Im looking for ways to benchmark my script.
I read on O'Reilly that I could use PEAR, and I tried it a few weeks ago
when I was running php 4.1.2.
Today I upgraded to php 4.2.1 and when I try to include the benchmark
the script is unable to find the PEAR benchmark class.|
include_once("Benchmark/Timer.php");|
Warning: Failed opening 'Benchmark/Timer.php' for inclusion
(include_path='.:/usr/local/lib/php')
Also on a side note, I dont know much about benchmarking utilities, but
what else is out there for windows/bsd??
Thanks

Re: [PHP] Re: Date?
Speaking of which. I was thinking about this this morning. Is there a part of the Unix timestamp that tells php what timezone to report. Reason why I ask, is I would like to offset the unix timestamp relative to where a server is to a particular user. So lets say the user is in Europe, and the server is in USA and the script is set to display date as 'H:i T', and I offset the unix timestamp to the user in Europe, would the timezone adjust to the European timezone... Im going to try on a windows box where I can change the date easily and see what happens...

Re: [PHP] OO Question
Im no OO coder but I did try this before.
I made (well started to anyway) a class that uses two other classes, and
yes,
$this->that->do_something() did work for me

[PHP] regex
Im expecting a string like foo.png.
Im trying to replace 'foo' with another value that I have.
Im trying this ->
$file = preg_replace('/([a-z][0-9]-_*)(.[a-z]{3,4})/i', $new_file .
"$2", $_FILES['upload']['name']);
The second regex group works ok, its the first one I cannot figure out.
It is supposed to contain alpha numeric characters and '_' and '-'.
Thanks for any input.

Re: [PHP] regex
Well Ive gotten
(.*)
and
([a-z]*[0-9]*_*-*)
to work thus far as the first group.
I would like to avoid option 1, and option 2 doesn't seem right....

[PHP] printf()
Im trying to make a dynamic printf().
By that I mean ->
function this($foo, $bar)
{
if (strlen($bar) == '0')
{
print($foo);
}
else
{
printf($foo, $bar);
}
}
Now it works if there is one argument passed, but it doesn't when there
is more than one.
$str = 'should';
this('This %s work', $str); // work
$str = 'is, a';
this('This %s just %s test', $str); // doesn't work
So I guess, arguments passed to it has to be physical arguments, and not
represented in a string.
Am I banging my head on a wall with this??
Thanks

Re: [PHP] printf()
Well I figured out a solution. Using a combination of explode() to
create an array from $bar,
check to see if $bar is an array and
feed the array to vprintf()

[PHP] preg_replace
When you think you got it, you don't get it..
Im trying to scan the link for =A-Z0-9_=, dump the '=' and evaluate the
remainder as a defined constant.
Yes its funny looking, but if I could get this going Im golden.
$bar is always returned with '=_L_OL_HERE=' as the link and not 'here'
as it supposed to be.
Any help would be appreciated.
Thanks
=_L_OL_HERE=';
$bar = preg_replace('/(=)([A-Z0-9_])(=)/e', ' . constant("$2") . ', $foo);
echo $bar;
?>

[PHP] Escaping escaped chars
Im trying to move some binary strings from mysql to postgresql,
and the binary strings has escape chars '\' in them.
I was told to double escape them like so -> '\\\'
Here is what Im trying ->
$data = '\0P Z\0<Îê˜Úµ'; // This is a representation from an mysql dump
$data2 = str_replace('/\', '/\/\/\', $data);
Im getting ->
Unexpected character in input: '\' (ASCII=92) state=1
I guess my str_replace() isn't correct.
Am I going about the right way to double escape them.
Thanks.

Re: [PHP] Escaping escaped chars
One of the guys over on the php-db list told me that to store the binary
string correctly in postrgresql, that I would
have to double quote whats already there.
So in essence, by the time it hits the database, it has to be ->
\\\0P Z\\\0<Îê˜Úµ
Any suggestions to modify the string like this...
Maybe I should be looking into one of the preg functions
Thank You.

[PHP] Stumped.
In a file with functions only, one of the functions is structured like ->
function foo()
{
if (isset($_POST['submit']))
{
/* DO SOME SQL */
header('location: x');
}
else
{
/* SHOW A FORM HERE */
}
}
I noticed today that when I turned off output buffering, that the header
redirect doesn't work anymore...
I turned on E_ALL error reporting, and I didn't get any errors.
I checked the file that called on this particular file, and there is no
'white space' before or after
I checked all included files that this function calls on and there is no
'white space' before or after
Are there any other reasons why header() would fail while output
buffering is off.
Im running php 4.2.1 on FreeBSD 4.5-R p6
Thanks
