How can the issue of a PHP file not being displayed be resolved in a PHP version 4.3.10 environment?

Issue: The PHP file may not be displayed due to incorrect file permissions or misconfigured server settings. To resolve this issue, ensure that the PHP file has the correct permissions set and that the server is configured to properly handle PHP files.

<?php
// Ensure correct file permissions
chmod("your_file.php", 0644);

// Check server configuration for handling PHP files
// Ensure PHP module is enabled in the server configuration
// Restart the server to apply any changes
?>
