What potential limitations or restrictions could hosting providers impose on PHP script execution time?

Hosting providers could impose limitations or restrictions on PHP script execution time to prevent resource abuse and ensure fair usage for all users on shared servers. This could lead to scripts being terminated prematurely if they exceed the allowed time limit. To address this issue, you can optimize your PHP scripts to improve performance and reduce execution time, or you can adjust the PHP configuration settings to increase the maximum execution time allowed for scripts.

// Increase maximum execution time to 60 seconds
ini_set('max_execution_time', 60);
