You can try this -

$new= array_map(function($v) {
    $temp = array_chunk($v, 2); // break in chunks of 2
    $final[]= array_shift($temp); // Take the first chunk out
    $second= array();
    foreach($temp as $t) {
        $second = array_merge($second, $t); // merge the rest chunks
    }
    if(!empty($second)) {
        $final[]= $second;
    }
    return $final;
}, $array);
