                            [image] => 0j1kjjzdv3ez07a0ee4lnmjb7_163.jpeg
                            [image_id] => 4
                            [text] => 
                            [date] => 1328577934
                            [comments] => 0
                            [first_image_id] => 4
                        )

                )

I want to sort this array by date and get something like : 

[follow] => Array
{
....
}
[pictures] => Array
{
....
}
[follow] => Array
{
....
}

If i understand your problem correctly, something like this should do it

function orderByDate($a, $b)
{
    return $a['date'] < $b['date'];
}

$newArray = $array['everything_list']['follow'] + $array['everything_list']['pictures'];
usort($newArray, 'orderByDate');
