You mean something like this...

implode(',', array_keys($some_arr));

... right? ) Here's documentation for array_keys; in short, when called with a single argument (an array), this function just returns all its keys (as array).

It's worth noting that this will work for either auto assigned indicies, or for those you assign yourself with square bracket notation.
