HTTP_USER_AGENT in email

[swirlee]

Assuming you're using the mail() function, just include $_SERVER['HTTP_USER_AGENT'] in the text you're sending. Like so:

Code: Select all

<?
   $recipient = 'swirlee@php-forum.com';
   $subject = 'This e-mail is spam';
   $message = 'The sender\'s HTTP_USER_AGENT is: ' . $_SERVER['HTTP_USER_AGENT'];
   mail($recipient, $subject, $message);
?>
