[PHP] why cant I: array_keys($arr)[0] ?

Why does PHP give a parse error if you do: echo array_keys($arr)[0]; It makes you assign the result of the function to a var first like this: $arr = array_keys($arr); echo $arr[0]; I just want to grab the 1st element of the array. Why does it make you do it in 2 lines instea
