Thread:Extension talk:Google AdSense 2/Imput adsense in an article

I saw this function on the Internet and I think it is a way to imput adsense in the body of an article. Does anyone has any idea how to improve it?

setHook( "adsensesearch", "renderass" ); } function renderass( $input, $argv ) { $output = '   '; return $output; } ?>
