IFF they just left one of your other sites, then you should be able to pass
a variable in the other site's header such as:


if the variable isn't set, then they came from a site you don't own.

or you could send them to a unique function-name where you can then record a
hit on that function-name.
function unique_name()
    $hit="came from my other site";
    pseudo code -- store $hit;
    function run_me(you really want to run)

Subject: [PHP] Tricky question - referrer from ousite, or from intern?

> Hi there,

> As you all know it is possible on php.net to pass a function name just

> My question is how can I make sure that they do come from outside and are
