What are some common reasons for a PHP script to work on one server but not on another?

One common reason for a PHP script to work on one server but not on another is differences in PHP versions or configurations between the servers. This can lead to compatibility issues with certain functions or syntax. To solve this issue, make sure that the PHP version and configurations on both servers are compatible with the script being executed. 

// Example code to check PHP version compatibility
if (version_compare(PHP_VERSION, '7.0.0', '<')) {
    die('This script requires PHP version 7.0.0 or higher.');
}
