Two simple examples of how to use ^ and $:
<?php
$hostname = 'www.php.net';
// remove www subdomain from a hostname
echo preg_replace( '/^www[.]/i', '', $hostname ) . PHP_EOL; // output:
php.net
// remove tld from a hostname
echo preg_replace( '/[.].{2,4}$/i', '', $hostname ) . PHP_EOL; // output:
www.php
?>
