Email Errors To Yourself Instead Of Showing It Publicly

Most servers are set to display an error message when an error occurred in one of your script. But, you may also want to get an email containing the error, instead of displaying it to the public.

The Script is given below:

<?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 . " ";

 // 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 users 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 doesnt exist)
echo $somevarthatdoesnotexist;
