How can PHP be configured to handle session IDs more efficiently to prevent sporadic session ID duplication?

To prevent sporadic session ID duplication in PHP, you can configure the session ID regeneration to occur more frequently. This can be done by setting the session.gc_maxlifetime and session.gc_probability directives in the php.ini file to lower values, which will trigger session ID regeneration more often.

ini_set('session.gc_maxlifetime', 3600); // Set session expiry time to 1 hour
ini_set('session.gc_probability', 1); // Set probability of session garbage collection to 1%
session_start();
