How can server settings affect the ability to edit or save large PHP files?
Server settings such as memory_limit and max_execution_time can affect the ability to edit or save large PHP files. To solve this issue, you can increase the values of these settings in your php.ini file or in your PHP script using ini_set() function.
// Increase memory limit
ini_set('memory_limit', '256M');
// Increase max execution time
ini_set('max_execution_time', 300);
