How can I get the current element number when I'm traversing a array?

I know about count(), but I was hoping there's a built-in function for getting the current field index too, without having to add a extra counter variable.

like this:

foreach($array as $key => value)
  if(index($key) == count($array) ....

You should use the key() function.

key($array)

should return the current key.

If you need the position of the current key:

array_search($key, array_keys($array));
