Remove first levels of identifier in array

Question

I think this has been up before, but could\'nt find any answer to it. If it\'s already answered please point me in the right direction with a link.

I have an array t

Answer 1

Below code will also achieve the same result.

$resultArray = array_map('current',$inputArray);

OR

$resultArray = array_map('array_pop',$inputArray);

Note: I have ignored OP's expected result keys. Because it is not possible to have the same keys in the array. The last key will replace the previous one if the same.
