What potential issues can arise when moving PHP scripts from a local environment to a server, specifically related to session data?

When moving PHP scripts from a local environment to a server, potential issues related to session data can arise if the server's session configuration differs from the local environment. To solve this issue, make sure the session settings in the php.ini file on the server match those on the local machine to ensure seamless session data transfer. 

// Set session configuration to match local environment
ini_set('session.save_path', '/path/to/session/directory');
ini_set('session.gc_probability', 1);
ini_set('session.gc_divisor', 1);
ini_set('session.gc_maxlifetime', 3600);
session_start();
