Basically I have an iframe of an external site, which has html that is auto-generated.

What I want to do is to use file_get_contents to get the html within that iFrame, which is hosted on my domain.

So something like this:

Code:
<iframe src="othersite.com"></iframe>
<?php
$contents = file_get_contents(//iFrame Content);
?>
I would love someone to point me into the right direction.
