  I have a simple contact form which I want to use to send an email from my website.  It all appears to work OK, however, for some reason whatever text is used on the submit button label is being appended to the end of the message field.
  
  The fields on my form are:  req_name, req_email, req_subject and req_message.
  
  The email that is sent contains the information as expected, the only problem is that at the end of the message the text from the submit button label is also included.
  
  I am very new to PHP (and web development in general) so any ideas would be greatly appreciated.  My code was obtained from a college course I attended and I am adapting it to my needs (I do not claim to understand the whole script):
  
  <?
  
  // Recipient of message (This can be changed via the form itself)
  $recipient .= '[email protected]';
  
  // Subject of message (This can be changed via the form itself)
  $subject = $req_subject;
  
  // This is a list of domains that can run EZ FormMail. Do not include
  // www, just the actual domain/ip address!
  $referers = array('website.com');
  
  // This is the page that users will be redirected to after the form is
  // processed successfully. You will need to create the page
  $success_url = 'http://www.website.com/contactform_OK.htm';
  
  // Your site URL
  $siteurl = 'http://www.website.com';

     echo ', to return to the previous page.';
  }
  // This part tells the script where to accept form data from. It specifies
  // the domain name and rejects the information if it's from another or
  // unauthorised source.
  
  function Check_Referer() {
     global $referers;
     $temp = explode('/', $_SERVER['HTTP_REFERER']);
     $referer = $temp[2];
     $found = false;
     foreach ($referers as $domain) {
