Can you provide examples or scenarios where $_SERVER['PHP_SELF'] and $_SERVER['SCRIPT_NAME'] may not be equal in PHP?

$_SERVER['PHP_SELF'] and $_SERVER['SCRIPT_NAME'] may not be equal in PHP when the script is accessed via a symbolic link or an alias. This can happen in scenarios where the server configuration maps different URLs to the same script, resulting in the discrepancy between the two variables. To ensure consistency, it's recommended to use $_SERVER['SCRIPT_NAME'] as it provides the actual path of the script being executed. 

$script_name = $_SERVER['SCRIPT_NAME'];
// Use $script_name instead of $_SERVER['PHP_SELF'] in your code
