What is the best practice for handling sessions in PHP scripts that need to run concurrently?

When handling sessions in PHP scripts that need to run concurrently, it is important to ensure that each session is isolated and does not interfere with others. One way to achieve this is by using session locking to prevent multiple scripts from accessing the same session data at the same time. This can be done by calling session_start() with the parameter 'true' to enable locking.

session_start(['cookie_lifetime' => 86400, 'use_strict_mode' => 1, 'cookie_samesite' => 'Strict', 'cookie_secure' => 1, 'cookie_httponly' => 1, 'use_cookies' => 1, 'use_only_cookies' => 1, 'cookie_domain' => 'yourdomain.com', 'cookie_path' => '/', 'cookie_lifetime' => 86400, 'gc_maxlifetime' => 86400]);
