Restructure multidimensional array

I'm trying to restructure an array but can't figure out how to rearrange it to output the id as the key, I want to change this:

Array
(
    [0] => Array
        (
            [0] => 16
            [1] => News
            [2] => News
            [3] => News
            [4] => News content
        )

    [1] => Arra开发者_如何学运维y
        (
            [0] => 17
            [1] => about-us
            [2] => About us
            [3] => About us
            [4] => About us content

        )

)

To this:

Array
(
    [16] => Array
        (
            [0] => News
            [1] => News
            [2] => News
            [3] => News content
        )

    [17] => Array
        (
            [0] => about-us
            [1] => About us
            [2] => About us
            [3] => About us content

        )

)

I created this demo script. This should work.

<?php

$original = array(0 => array(16, 'News', 'Etc'), 1 => array(35, 'Be', 'Here'));

foreach($original as $key => $value) {
  $new = array_shift($value);
  $newarray[$new] = $value;
}

echo '<pre>'.print_r($original,1).'</pre>';
echo '<pre>'.print_r($newarray,1).'</pre>';
?>

Output:

Array
(
[0] => Array
    (
        [0] => 16
        [1] => News
        [2] => Etc
    )

[1] => Array
    (
        [0] => 35
        [1] => Be
        [2] => Here
    )

)

Array
(
[16] => Array
    (
        [0] => News
        [1] => Etc
    )

[35] => Array
    (
        [0] => Be
        [1] => Here
    )

)
