Why Does My `session_start()` Call Still Cause Permission Errors Even After Setting /tmp to 777?

Resolving Permission Errors with session_start() Call

When encountering permission errors upon calling session_start(), despite setting the /tmp folder permissions to 777, there are two primary solutions to consider.

1. Modify Session Path

One approach is to modify the session save path to a directory where you have write permissions. This can be achieved by using the session_save_path() function. For instance:

<code class="php">session_save_path('/my_custom_path');
session_start();</code>

2. Contact Server Administrator

Alternatively, you can reach out to the server administrator to investigate any underlying issues with the /tmp directory. This could involve problems with file system permissions, disk space limitations, or other system-level conflicts.

For additional reference, you can consult the PHP documentation on session save path: http://php.net/manual/en/function.session-save-path.php
