note 20589 added to ref.url

Hi, I'd like to have a php-script that reads the URL of the previous page (the one the page is loaded from) and checks if it contains the value "www.mysite.com", and if it does that it gives the value "3" to $value. I'm very new to php. Does anyone have an idea how I can realise this?? All help is very welcome!! Thanks in advance, Rolf. -- http://www.php.net/manual/en/ref.url.php http://master.php.net/manage/user-notes.php?action=edit+20589 http://master.php.net/manage/user-notes.php?action=delete+20589 http://master.php.net/manage/user-notes.php?action=reject+20589
