How can I disable certain pages in a dynamic site

I have an auto-updated youtube api website where the site urls are always in the form

www.mydomain.com/video/yt.php?$TITLE

or

www.mydomain.com/video/$ID/$TITLE.html

where $ID is the video id and $TITLE is the video title.

Now I want to disable/ban any page that the $TITLE contains a certain word (e.g. sex).

Any idea how can I do that?

 

You can use mod_rewrite to redirect them to home page etc.

 

www.mydomain.com/video/yt.php?$TITLE

In yt.php add the following php code at the very top:

<?php
//example...
$banned_words = array('sex');
if(in_array($_GET['yt'], $banned_words)) {
header('Location: http://'.$_SERVER['HTTP_HOST']);
}

?>

PHP:

 

i will try the trick, thank you danx10
