What are some common causes of Internal Server Errors in PHP scripts?

Internal Server Errors in PHP scripts can be caused by various issues such as syntax errors, memory limit exhaustion, or server misconfigurations. To solve this issue, it is recommended to check for any syntax errors in the PHP script, increase the memory limit in the PHP configuration file, or contact the server administrator to resolve any server misconfigurations.

<?php
// Increase memory limit
ini_set('memory_limit', '256M');
?>
