php 5.0.4

prabhatsoni · 03-13-2006, 02:39 AM

The sessions are not working in php5.0.4.

In earlier versions the same was working. Even the simple scripts as below are not working.

Code:

<?php
// page1.php

session_start();

echo 'Welcome to page #1';

$_SESSION['favcolor'] = 'green';
$_SESSION['animal']   = 'cat';
$_SESSION['time']     = time();

// Works if session cookie was accepted
echo '<br /><a href="page2.php">page 2</a>';

// Or maybe pass along the session id, if needed
echo '<br /><a href="page2.php?' . SID . '">page 2</a>';
?>

and

Code:

<?php
// page2.php

session_start();

echo 'Welcome to page #2<br />';

echo $_SESSION['favcolor']; // green
echo $_SESSION['animal'];   // cat
echo date('Y m d H:i:s', $_SESSION['time']);

// You may want to use SID here, like we did in page1.php
echo '<br /><a href="page1.php">page 1</a>';
?>

Any help ?

what error messages are you getting in the apache logs? If you are getting segmentation faults then it could be to do with some of the PHP packages that you have installed.

I had the same problem, and I removed all the PHP packages that I was not using for my build and the session problem went away.

Check your php.ini and make sure the session.save_path is set to somewhere writable.

Hello friends,
In php.ini:
session.save_path = "/var/lib/php/session"

The permissions of this directory are : drwxrwx---

The httpd log is
log

Code:

PHP Warning:  session_start() [<a href='function.session-start'>function.session-start</a>]:

I changed permissions to drwxrwx-wx

But still it does not work.

chown the directory to whoever httpd runs as.

Hello,
Sorry for taking time to respond. In fact I was out of station for a few days. And In India "HOLI" the festival of colors is celebrated with much gusto and enthusiasm, and I was busy in it.

Ok, the problem.

After changing the permissions of the directory /var/lib/php/sessions to drwxrwx-wx, I shut down the PC and restarted it, and I find that the sessions are working ok.

Thanks a lot for this help.

The directory is owned by root. Would not it create any problem if instead of allowing "others" to "write" and "cd" into it, I simply chown it to apache.
What is the established norms or practice. Ibelieve both would serve the purpose insofar as the sessions are concerned. Will it have any implications for the security ?
