getting the domain address of an email address

Question

I have an issue of getting the domain address of an email, In the substring this is the code.

$to=$son_im_email;//udemesamuel256@gmail.com
$goto_small=strtolower($to);
//this is what i want to achieve is just to get the 'GMAIL.COM' from the email address.

Answer 1

How about

$email = 'test@example.com'; $domain = substr(strstr($email, '@'),1); echo $domain;

Also try

$email = 'test@gmail.com'; $domain = explode('@',$email); $domain = $domain[1]; echo $domain ;

Answer 2

An alternative to using "explode" or a regular expression:

<?php
  $address = 'someuser@my.smalldomain.info';
  $details = parse_url('mailto://'.$address);
  var_dump($details);
?>

The output:

array(3) {
  'scheme' =>
  string(6) "mailto"
  'host' =>
  string(19) "my.smalldomain.info"
  'user' =>
  string(8) "someuser"
}

So you can use the domain name as $details['host'].

Answer 3

Documentation from http://uk1.php.net/preg_match

$matched = preg_match("@.+$", $goto_small, $matches);

$matched will be an int telling you whether @anything could be found, and $matches will be an array whose first element will be the @ and everything after it, if the function suceeded.
