How do I get the output of PHP/ Javascript so I can send it through mail function?

[Tom B]

I am making a PHP script to send an email with information on the visitor.
In order to convert the IP address to the city/ country it is put through some other sites, but the only free ones do it via Javascript.
When I send it through mail( ) I get the '<script src=""></script>'....
What I want is the output of that script.
Is there anyway to dot this?
Sorry, I'm new to PHP, thanks.

var $js_city = echo "<script> JS script </script>"

Mail(bla bla..)

Echo outputs what it processes, such as html text/jpg/headers..
