Er -- no. Go read its definition again -- you *may* pass it a value for which you want the corresponding keys, but by omitting the value argument you may also ask for *all* of the keys of your array. > I want to > get the value of > the key but all I know is the index. First of all, I presume this means that, for example, if $index==4, you want to know what the key of the 4th array element is? In that case, the following, whilst not ideal, may be your best solution: $keys = array_keys($array); $required_key = $keys[$index]; Cheers!
