Google and Echo PHP

So I tried to use a config.php file and use something like $adsense_pub ="", then I called in in index.php within the adsense code using <php echo ... bla bla blah..
When I view the source code on the site, the adsense code is perfect, but nothing is being displayed?..Same goes for when I try to just include a file that contains the adsense code seperately... Is this because it goes against google adsense TOS, or am I retarded and have some kind of coding wrong?

Is there a way to define the PUbID outside of the actual pages and still have it work?

 

Yes. check any free php proxy script. They've done it.

 

They have to use a proxy to make this possible?

 

I figured it out..sorry..bad post..i'm retarded.
