Well, I try to go to the manual at www.php.net first but sometimes it's a little confusing or assumes you know more then you do. Also I really don't know what to search for for some questions. And I spend 2 hours looking through the manual when I could have just posted in 5 min and gotten the answer responded.
I try not to ask stupid or too simple questions but sometimes it's the best thing.
Perhaps a good idea is to build a faq from the forum for newbies.
Also as long as the questions are clear a pro can probably answer them in a matter of minutes.
I don't know..i just come here for help =)
