In what ways can the PHP script be optimized to handle potential timeouts or server configurations that may affect its execution on different PHP versions?

To optimize a PHP script to handle potential timeouts or server configurations, you can adjust the PHP settings related to execution time and memory limit. This can help prevent timeouts and ensure the script runs smoothly on different PHP versions.

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

// Set maximum memory limit to 128MB
ini_set('memory_limit', '128M');
