What will be the output of the following PHP code?

<?php
$num = array ("Zero","One", "Two", "Three", "Four","Five");
$subset = array_splice ($num, 3);
print_r ($subset);
?>

Array
(
    [0] => Three
    [1] => Four
    [2] => Five
)

Array
(
    [0] => Three
    [1] => Four
    [2] => Five
    [3] => Zero
)

The array_splice() function removes all elements of an array found within a specified range.
