How can PHP's memory limit and execution time settings be adjusted to prevent server crashes?

To prevent server crashes due to PHP memory limit and execution time issues, you can adjust these settings in your PHP configuration file (php.ini) or within your PHP script using the ini_set() function. By increasing the memory_limit and max_execution_time values, you can ensure that your PHP scripts have enough resources to run without causing server crashes.

// Adjust PHP memory limit and execution time settings
ini_set('memory_limit', '256M');
ini_set('max_execution_time', 300);
