Question

I know this would be an easy one but I don’t get it. All answered I found on the net was… too complex to me, maybe.

Here is my typical array:

array(
(int) 0 => array(
    'Conversation' => array(
        'id' => '1',
        'created' => '2012-08-04 00:00:00'
    ),
    'ConversationUser' => array(
        (int) 0 => array(
            'id' => '1'
        ),
        (int) 1 => array(
            'id' => '2'
        )
    )
),
(int) 1 => array(
    'Conversation' => array(
        'id' => '2',
        'created' => '2012-08-01 00:00:00'
    ),
    'ConversationUser' => array(
        (int) 0 => array(
            'id' => '1'
        ),
        (int) 1 => array(
            'id' => '2'
        )
    )
));

I want to sort my data with [‘Conversation’][‘created’] date, asc or desc.

Any simple answer ? 😛

P.S. I can’t use MYSQL sort, I retrieve the data one by one and create that array.

Answer 1

Use usort() :

usort($your_array, function($a, $b){
    $a = strtotime($a['Conversation']['created']);
    $b = strtotime($b['Conversation']['created']);

    if ($a == $b) {
        return 0;
    }
    return ($a > $b) ? -1 : 1;
});
