/**
 * Email发送错误
 *
 * @param 
 * @author php教程 www.idcnote.com
 **/
// 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;
