When doing development, operating session sometimes encounters this problem: Warning: session_start () [function.session-start]...

System environment: WIN2003+IIS6+PHP5.2.12

PHP has an error similar to the following:

Warning: session_start () [function.session-start]:. Failed: No such file or directory. Wait for the situation

You can try to change the session.auto_start = 0 to session.auto_start = 1 in the php.ini file.

If the problem persists after restarting IIS

That is, the session variable requires temporary file space for the system and read and write permissions.

Find session.save_path = in php.ini and set a valid folder path

For example: session.save_path = "c:\ php5\ session_temp" and add permissions for this folder to give everyone permission to modify writes.

PHP environment:

OS:CentOS release 5.2 (Final)

Apache:

Server version: Apache/2.2.3

Server built: Jan 15 2008 20:33:30

Php:

PHP 5.1.6 (cli) (built: May 24 2008 14:07:53)
