In a quick note from PHP.net today, they've finally put into place the "function suggestion" ability for the search box at the top of the site.

Surely, some of our visitors are back at work for a few days between holidays, and hopefully they will find our post-christmas gift useful. The function list suggestions we started to test a year ago seemed to be working better as some bugs were found and fixed, so it was time to make the result available on all php.net pages.

Whenever you type something into the search field, while having the function list search option selected, you will get a list of suggested functions starting with the letters you typed in. You can browse the list with the up/down keys, and you will be able to autocomplete the function name with the spacebar.

Not only is this amazingly useful, but it can really help when you just can't remember that function name. No more going back to the function listing in the manual to look for the correct function. (Of course, you can just search for things like "array" and go straight to the main info page for them as well.)
