How to extract domain name from an e-mail address string

If, for any reason, you need to extract the domain from an e-mail address (or from multiple e-mail address that are in a database) then you can use this function:

<?php
function getDomainFromEmail($email)
{
// Get the data after the @ sign
$domain = substr(strrchr($email, "@"), 1);

return $domain;
}

// Example

$email = 'the_username_here@yahoo.com';

$domain = getDomainFromEmail($email);

echo $domain; // yahoo.com
?>

 The archive is made using WinZip 12.0. If you're having problems unzipping it, consider using WinRar, WinAce or a similar software to extract the files from the archive.
