I have a md array that I am trying feverishly to properly sort by the date.

So far I've got:

usort($respArr, function($a, $b){
        $t1 = strtotime($a['PublishDate']);
        $t2 = strtotime($b['PublishDate']);
        return $t1 - $t2;
    });

array_reverse($respArr);
echo '<pre>';
print_r($respArr);
echo '</pre>';
echo '<hr />';

Here's some of the output from the above:

However, the array is not reversed, as you can tell above. Can anyone help me with this? It's showing me that the array is indeed sorted by the 'PublishDate', however, in the reverse order that I need it in.

Thanks

The actual problem is you're not assigning the result of array_reverse to anything

// change this
array_reverse($respArr);

// to this
$respArr = array_reverse($respArr);

durrrr.... LOL Is there any way I can make this into a function? –  o7th Web Design Mar 21 at 13:53
 
untested: function reveseme(&$array){$array=array_reverse($array);return;} $array=array(1,2,3,4,5); reveseme($array); This should do it. –  TecBrat Jul 24 at 20:53

Try this :

$arr  = your array;
$sort = array();
foreach($arr as $k=>$v) {
    $sort['PublishDate'][$k] = $v['PublishDate'];
}

array_multisort($sort['PublishDate'], SORT_DESC, $arr);

echo "<pre>";
print_r($arr);

But make your date prperly formated, else this may not work. format it to yyyy-mm-dd hh:mm:ss
