email validation checking

[scorpioy]

I found a function that does email validation checking

function validate_email($email)
{

   // Create the syntactical validation regular expression
   $regexp = "^([_a-z0-9-]+)(\.[_a-z0-9-]+)*@([a-z0-9-]+)(\.[a-z0-9-]+)*(\.[a-z]{2,4})$";

   // Presume that the email is invalid
   $valid = 0;

   // Validate the syntax
   if (eregi($regexp, $email))
   {
      list($username,$domaintld) = split("@",$email);
      // Validate the domain
      if (getmxrr($domaintld,$mxrecords))
         $valid = 1;
   } else {
      $valid = 0;
   }

   return $valid;

}

It works well when giving a non-sense email address, like: grerg@rggerg, but when giving a correct domain name, or even just rggerg.com would cause the error.

When I use something like [e-mail]. The error is 'Fatal error: Call to undefined function: getmxrr() in c:\program files\apache group'

Does anyone know why would this happen? Thanks.

getmxrr is not available on windows

So what functions can I use in Windows?

Thanks

Could try Net_DNS

Net_DNS still encounters the same problem. Is there any other ways to check validity?

Thanks for any help.

So, it doesn't work. Did you notice that hte solution recommended was NOT part of the base install, but rather a project of PEAR, which is all written IN PHP/?

Make sur eyou have all the libaries in place, then post again.

Could you tell me how do I install the library? Where can I download it?

Thanks
