What could be causing a PHP form to not display any error messages when submitting data?

The issue of a PHP form not displaying error messages when submitting data could be due to error reporting being turned off or error messages being suppressed in the code. To solve this issue, you can enable error reporting in your PHP script by setting error_reporting(E_ALL) and display_errors to On in your php.ini file or within your PHP script. 

<?php
// Enable error reporting
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Your PHP form processing code here
?>
