PHP: Email PHP errors instead of displaying it Never actually used this one

<?php // 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)
