Strip tags in PHP

strip_tags() function will return the string with stripped(removed) HTML and PHP tags.

<?php

$string = '<h2>This is PHP Rokcers blogspot.</h2><!-- Comment --> <a href="http://phprockers.blogspot.com/">phprockers</a>';

echo strip_tags($string);

?>

echo strip_tags($string, '<h2><a>');

?>
