here's my code, on the last line when i print out the contents of youtube.com it shows i'm not logged in.. anyone know what i'm doing wrong here? to login to google you need to grab the GALX and dsh values and i'm doing so. this is such a headache!

Google is right :) You see, you curl_init( ) over and over, which means you start new sessions every call to your curl_get and curl_post functions. You should only init once and pass along the resource you retrieve. That should solve your problem.

EDIT: Took the liberty of rewriting your code to illustrate:
