将数组拆分为多个并在新数组中添加下两个项目

Question

I have an array, like:

$list = array('a', 'b', 'c', 'd', 'e',
              'f', '1', '2', '3', '4',
              '5', '6', '7', '8', '9');

And I want to split this array, and add every next two items in a new array as a group, like:

$new_list = array(
    array('a', 'b'),
    array('c', 'd'),
    array('e', 'f'),
    array('1', '2'),
    array('3', '4'),
    array('5', '6'),
    array('7', '8'),
    array('9'), // note that this one here is alone!
);

But I want to do this with foreach or something. I only know I can divide length of my array with 2 and use round or floor PHP functions to get a whole number, but I can't figure out how to group items of this array in two items per array.

Please help me, my brain is overflowing...

Answer 1

$list = ['a', 'b', 'c', 'd', 'e',
    'f', '1', '2', '3', '4',
    '5', '6', '7', '8', '9'];

$list2 = [];

$c = 0;
$temp_array = [];
for ($i = 0; $i < Count($list); $i++)
{
    $c++;
    array_push($temp_array, $list[$i]);
    if ($c >= 2)
    {
        array_push($list2, $temp_array);
        $temp_array = [];
        $c = 0;
    }
}

print_r($list2);

echo '<br />List2: ' . count($list2) . '<br />List: ' . count($list);

EDIT: or the solution which Mark Baker provided with the array_chunk() function. It's less code.
