Possible to turn an ifarme's parent's filename into a PHP Variable?

Is it possible to pass the filename of an iframe's parent to a PHP variable? I am trying to dynamically generate an iframe that contains information that depends on the p开发者_StackOverflow社区arent's filename. The iframe will be placed into multiple pages and it will be generate info based on what page it is in.

You should add a query-string parameter to the <iframe>'s URL.
