Undefined Function: Getmxrr()

Good Afternoon,

I have created a few forms on my site that the user will fill in and when it is submitted a php page processes the data, including E-mail validation, and sends me a mail to the chosen address.

I have tested it in IE8 and Safari, it works fine. When I try the form using Firefox, I get the Undefined Function: Getmxrr() error.

Here is the code I use

function checkEmail($email) 
{
   if(eregi("^[a-zA-Z0-9_]+@[a-zA-Z0-9\-]+\.[a-zA-Z0-9\-\.]+$]", $email)) 
   {
      return FALSE;
   }

   list($Username, $Domain) = split("@",$email);

   if(getmxrr($Domain, $MXHost)) 
   {
      return TRUE;
   }
   else 
   {
      if(fsockopen($Domain, 25, $errno, $errstr, 30)) 
      {
         return TRUE; 
      }
      else 
      {
         return FALSE; 
      }
   }
}

 if(checkEmail($email) == FALSE) 
{
   header( "Location: $errorurl" );
   exit ;
} 
else 
{

Code then processes the rest of form as long as E-mail is valid

I dont think it is a fault with the coding, but any advice would be welcome.

Regards,

I'm not sure what the browser has to do with this issue, as it would be executing on the server, no?

Depending on your PHP version, < 5.3 on Windows doesn't support the getmxrr() function :

Thanks Tonsil,

I am well aware of the older version of windows not supporting the function. I have looked into the problem for a number of weeks before I posted my query. I even tried other ways of processing the forms, but could not get the results I wanted, so returned to this program.

As I said in my previous mail, the code works fine when I access it using the MSIE and Safari browsers, so therefore I assume it is not a server issue. It is only when I use the Firefox browser that the error occurs? That is why I think/thought it is/was a browser issue!

I just wondered if anyone else had this problem and if there was a known work around if they did.

Cheers

If PHP is telling you "Undefined Function: Getmxrr()" then it's a problem on the server. If I were you I would try to figure out what's different between the Firefox submission and IE. Are you seeing this error in the browser, or in an error log? If in the browser, are you sure both browsers are hitting the same server? Or is the Firefox instance on a separate machine that has a hosts entry pointing to a development server or something?

If that's not it, do some var_dump debugging right before the problem line and try to figure out what's different. I cannot imagine what difference would make one browser work and the other not in this case. Either the function exists or it doesn't.
