Multidimensional array of PHP arrays Does array_reverse array not work?

I have a Multidimensional array that I am trying to feverishly sort correctly by date.

So far I have received:

 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 are some of the results above:

 Array ( [34] => Array ( [Title] => o7thwd: Partnered with Internet Services Inc., to offer complete online presence! http://t.co/1SgAF66Tbf @ISI_Cloud [Link] => http://twitter.com/o7thwd/statuses/306088158574022656 [PublishDate] => 2/25/2013 12:07:58 PM [Image] => [Description] => o7thwd: Partnered with Internet Services Inc., to offer complete online presence! http://t.co/1SgAF66Tbf @ISI_Cloud ) [35] => Array ( [Title] => o7thwd: Hangin with Mama Bear giving her the basics of social networking [Link] => http://twitter.com/o7thwd/statuses/307916797066240000 [PublishDate] => 3/2/2013 1:14:19 PM [Image] => [Description] => o7thwd: Hangin with Mama Bear giving her the basics of social networking ) [36] => Array ( [Title] => o7thwd: o7th Web Design Articles http://t.co/plP8OkB7So [Link] => http://twitter.com/o7thwd/statuses/308687737400205313 [PublishDate] => 3/4/2013 4:17:46 PM [Image] => [Description] => o7thwd: o7th Web Design Articles http://t.co/plP8OkB7So ) [37] => Array ( [Title] => o7thwd: finished up my GUI for a YUI minifier: http://t.co/7DKLoCXJHw [Link] => http://twitter.com/o7thwd/statuses/309309871931682816 [PublishDate] => 3/6/2013 9:29:54 AM [Image] => [Description] => o7thwd: finished up my GUI for a YUI minifier: http://t.co/7DKLoCXJHw ) [38] => Array ( [Title] => o7thwd: o7th Web Design Articles http://t.co/QAIUO2Qjko [Link] => http://twitter.com/o7thwd/statuses/314356123027243008 [PublishDate] => 3/20/2013 8:41:54 AM [Image] => [Description] => o7thwd: o7th Web Design Articles http://t.co/QAIUO2Qjko ) [39] => Array ( [Title] => SkorIn2: starting new desktop app to compliment the web app [Link] => http://twitter.com/SkorIn2/statuses/314718985725804545 [PublishDate] => 3/21/2013 8:43:48 AM [Image] => [Description] => SkorIn2: starting new desktop app to compliment the web app ) )

However, the array is not the reverse, as you can say above. Can anyone help me with this?
This shows me that the array is indeed sorted by "PublishDate", however, in the reverse order in which I need it.

The actual problem is that you are not assigning the result of array_reverse to anything

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

Try the following:

 $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 pre-formed, otherwise it may not work. format it to yyyy-mm-dd hh:mm:ss
