Array uasort not doing what I want

[Ninjakreborn]

I am probably using it wrong but this isn't working.

 

	function user_sort($a, $b) {
		if (strtotime($a['news_date']) > strtotime($a['news_date'])) {
			return 1;	
		}
	}
	uasort($data, user_sort);

 

The data object looks like this.

Any one can help me figure out why this isn't working?  I basically just want to short the array by the "news_date" value with the newest

values showing up first.

Array

(

    [427] => Array

        (

            [news_id] => 427

            [company_id] => 16

            [news_date] => 05/13/2010

            [content] =>

            [expiration_date] => 06/30/2010

            [is_active] => 1

            [is_featured] => 0

            [is_news] => 1

            [is_portfolio] => 1

            [featured_description] =>

            [created_date] => 05/22/2010

            [short_title] =>

            [sortOrder] => 1

            [hide_news_page] => 0

        )

 

    [505] => Array

        (

            [news_id] => 505

            [company_id] => 72

            [news_date] => 05/15/2010

            [abstract] =>

            [content] =>

            [expiration_date] =>

            [is_active] => 1

            [is_featured] => 0

            [is_news] => 1

            [is_portfolio] => 1

            [featured_description] =>

            [created_date] => 0000-00-00

            [short_title] =>

            [sortOrder] => 2

            [hide_news_page] => 0

        )

 

    [439] => Array

        (

            [news_id] => 439

            [company_id] => 38

            [news_date] => 2009-09-08 00:00:00

            [content] =>

            [expiration_date] =>

            [is_active] => 1

            [is_featured] => 0

            [is_news] => 1

            [is_portfolio] => 1

            [featured_description] =>

            [created_date] => 0000-00-00

            [short_title] => testdata

            [sortOrder] => 3

            [hide_news_page] =>

        )

I also just tried something along the lines of:

<?php
//>> GET DATA AND SET LOCAL DATA OBJECTS
	$objDataCollection	= $objData->get_news();
	function user_sort($a, $b) {
		$date1 = strtotime($a['news_date']);
		$date2 = strtotime($a['news_date']);

		if ($date1 == $date2) return 0;
		return ($date1 > $date2) ? -1 : 1;
	}
	uasort($objDataCollection, user_sort);

?>

<?php
//>> GET DATA AND SET LOCAL DATA OBJECTS
	$objDataCollection	= $objData->get_news();
	function user_sort($a, $b) {
		//$date1 = strtotime($a['news_date']);
		//$date2 = strtotime($a['news_date']);

		if ($a == $b) return 0;
		return ($a > $b) ? -1 : 1;
	}
	uasort($objDataCollection, user_sort);
?>

This almost works but not entirely...for some reason some dates are off.  Any advice?
