Split indexed single dimension array into groups of X (2 dimension array)

[MattyUK]

If I have a single dimensioned indexed array that I want split into groups what is the best way to do this?

If I have this:

Array
(
    [0] => Value0
    [1] => value1
    [2] => value2
    [3] => value3
    [4] => value4
    [5] => value5
    [6] => value6
    [7] => value7
    [8] => value8
    [9] => value9
    [10] => value10
    [11] => value11
    [12] => value12
    [13] => value13
    [14] => value14
    [15] => value15
    [16] => value16
    [17] => value17
    [18] => value18
    [19] => value19
    [20] => value20
    [21] => value21
    [22] => value22
    [23] => value23
    [24] => value24
    [25] => value25
    [26] => value26
)

but I need this:

Array
(
    [0] => Array
        (
	    [0] => Value0
	    [1] => value1
	    [2] => value2
	    [3] => value3
	    [4] => value4
	    [5] => value5
	    [6] => value6
	    [7] => value7
	    [8] => value8
        )

    [1] => Array
        (
	    [0] => value9
	    [1] => value10
	    [2] => value11
	    [3] => value12
	    [4] => value13
	    [5] => value14
	    [6] => value15
	    [7] => value16
	    [8] => value17
        )

    [2] => Array
        (
	    [0] => value18
	    [1] => value19
	    [2] => value20
	    [3] => value21
	    [4] => value22
	    [5] => value23
	    [6] => value24
	    [7] => value25
	    [8] => value26
        )
)

What is the most efficient way forward. I'm using using PHP 5.2

Thanks.

array_chunk()

PHP Code:

$output_array = array_chunk($input_array, 9);
echo '<pre>'.print_r($output_array, true).'</pre>';

OO thanks. I hadn't stumbled across array_chunk before.
