What could be causing the PHP window to close unexpectedly when trying to open a PHP file?

The PHP window may be closing unexpectedly due to syntax errors or issues with the PHP configuration. To solve this issue, you can check for syntax errors in your PHP file, ensure that PHP is properly installed and configured on your system, and make sure that your PHP file is being executed correctly.

<?php
// Your PHP code here
// Make sure there are no syntax errors and PHP is properly configured
// Ensure that the PHP file is being executed correctly
?>
