What are common server settings that may affect PHP scripts, such as max_execution_time and memory_limit?

Common server settings that may affect PHP scripts include `max_execution_time` and `memory_limit`. `max_execution_time` sets the maximum time in seconds a script is allowed to run before it is terminated, while `memory_limit` sets the maximum amount of memory a script can consume. If your PHP script is timing out or running out of memory, you may need to adjust these settings in your server configuration.

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

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