Write a PHP script to extract the user name from the email ID

PHP is a server scripting language, and It is a powerful tool for making interactive and dynamic Web-pages. I have used WampServer 2.2 for following example.

<?php
$emailid  = 'techstudy@gmail.com';
$username = strstr($emailid, '@', true);
echo $username."\n";
?>

Result:

techstudy
