Question

I have a single array such as this:

array('one','two','three','four','five','six','seven')

I’m using a foreach to iterate through this and I’d like to build an array like this:

array(
    array('one'),
    array('two')
),
array(
    array('three'),
    array('four')
),
array(
    array('three'),
    array('five')
),
array(
    array('six'),
    array('seven')
)

Any suggestions on how do this?

Thanks!

Use array_chunk.
From the PHP Manual:

array array_chunk ( array $input , int $size [, bool $preserve_keys = false ] )

Chunks an array into size large chunks. The last chunk may
contain less than size elements.

In your case you need $output_array = array_chunk($input_array, 2);

And then if you want to convert the leaves to arrays:

function leaves_to_array(&$item, $key)
{
    if (!is_array($item))
        $item = array($item);
}

array_walk_recursive($output_array, 'leaves_to_array');
