Write a PHP script to select first 6 words from the following string

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
$mystring = 'Techstudy - The Complete Debugging Solution (techstudy.org)';
echo implode(' ', array_slice(explode(' ', $mystring), 0, 6))."\n";
?>

Result:

Techstudy - The Complete Debugging Solution
