Are there any security concerns to consider when implementing a session timeout in PHP?

When implementing a session timeout in PHP, one security concern to consider is session fixation attacks, where an attacker could force a user to use a specific session ID. To mitigate this risk, you should regenerate the session ID on every request or after a certain period of time. This helps prevent attackers from hijacking a user's session. 

// Set session timeout to 30 minutes
ini_set('session.gc_maxlifetime', 1800);

// Regenerate session ID every request
session_start();
session_regenerate_id(true);
