Are there any potential issues with using ini_set to change session timeout in PHP?

Using ini_set to change session timeout in PHP may not always work as expected, especially if the session has already been started. It is recommended to set the session timeout using session.gc_maxlifetime before starting the session to ensure that the changes take effect.

php 
// Set session timeout before starting the session
ini_set('session.gc_maxlifetime', 3600); // 1 hour timeout

// Start the session
session_start();
