}

?> 
The Script Check if the referer is one of the arrays which is :
$okaysites = array("http://phpscriptcenter.com","http://www.phpscriptcenter.com");
but fairly that doesn't work. the script didn't work with me Until i make the referer check for a specific Webpage for example :
http://phpscriptcentre.com/url.html << if the link was Pressed from there it will Pass else it will redirect to the Chosen site
it didn't work also for a Forum topic i put the referer to check with the thread id but it didn't work
..............................................
all what i want how to make the Script pass allllll links opened from my domain www.domain.com
or i have another idea instead of checking the Exact referer can anybody Edit the code to check if the referer contain a (Word) which is my Domain name like www.mysite.com
so the script check if the referer contain mysite if yes Continue <<<

thx in advance
