Error-handling in PHP can be complex, and getting a good way of having clear and good error reporting and maintaining security, by not displaying to much to the public, can be difficult. Maybe sending errors to developers per email could be a good tool for you. Check out the following example code:

// Our custom error handler
function nettuts_error_handler($number, $message, $file, $line, $vars)

{
	$email = "
		<p>An error ($number) occurred on line
		<strong>$line</strong> and in the <strong>file: $file.</strong>
		<p> $message </p>";

	$email .= "<pre>" . print_r($vars, 1) . "</pre>";

	$headers = 'Content-type: text/html; charset=iso-8859-1' . "\r\n";

	// Email the error to someone...
	error_log($email, 1, 'you@youremail.com', $headers);

	// Make sure that you decide how to respond to errors (on the user's side)
	// Either echo an error message, or kill the entire project. Up to you...
	// The code below ensures that we only "die" if the error was more than
	// just a NOTICE.
	if ( ($number !== E_NOTICE) && ($number < 2048) ) {
		die("There was an error. Please try again later.");
	}
}

// We should use our custom function to handle errors.
set_error_handler('nettuts_error_handler');

// Trigger an error... (var doesn't exist)
echo $somevarthatdoesnotexist;
