Lookup for function

As a developer, i have the same kind of feeling like the developer of this site , when doing some developing work, always need to reference some site for the function or usage , some time it is really frustrated.

but thx that he develop this service/tools that can help most of the developer, an ajax function/code look up tools/service, it support php, mysql, javascript and css, weee what a good combo which can make a perfect site, you just type in the code/function that you want to look for, the site will auto generate out all the possible answer, some of them even got example ..

the develop did recommend to use this tools at the sidebar , which i still trying hard to figure how to do that !
