What steps can be taken to troubleshoot PHP scripts that encounter "Maximum execution time exceeded" errors?

When a PHP script encounters a "Maximum execution time exceeded" error, it means that the script took longer to execute than the maximum allowed time set in the server configuration. To troubleshoot this issue, you can increase the maximum execution time limit in your PHP configuration settings or optimize your script to reduce its execution time.

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