Is it a best practice to append a ".dat" extension to URLs in PHP to bypass server errors?

Appending a ".dat" extension to URLs in PHP is not a best practice to bypass server errors. It is better to address the root cause of the server errors rather than trying to work around them in this manner. This approach can lead to confusion and potential security vulnerabilities.

// Example of a potential workaround using a .dat extension
$url = "http://example.com/file.php.dat";
header("Location: $url");
exit();
