It should help you:

<?php
$your_array  = [0=>['array1'], 1=>['array2'],2=>['array3'], 3=>['array4'], 4=>['array5']];
$new_array   = [];
$first       = array_shift($your_array);
$last        = array_pop($your_array);
$array       = array_merge($first, $last);
$new_array[] = $array;
$new_array[] = $your_array;
?>
