PHP - Php Sort Array By Date

Hello,

I'm making a imagegallery and when someone upload a new image that image has to appear as first picture of the gallery.
I'm using an array for the files, but how can I sort the files on date, newest first.?

<?php
$n = 0;
$pathToThumbs = "images/tekeningen/";
$dir = opendir( $pathToThumbs );
while (false !== ($fname = readdir($dir))){
      
      // strip the . and .. entries out
     if ($fname != '.' && $fname != '..'){
     $tekeningen[$n] = $fname;
    } echo $tekeningen[$n]."<br />"; 
     $n = $n +1;
}
   closedir( $dir );
?>


I found solutions with ksort and filemtime, but I don't understand them and/or they didn't work for me.

Hello all!   I have this array of objects:

Array
(
    [0] => stdClass Object
        (
            [first_name] => test
            [last_name] => test
            [title] => test
            [id] => 34
            [type] => 4
            [manager] => 4
            [email] => p@yahoo.com
            [date] => 2014-09-21 07:23:12
            [status] => 2
            [approval_date] => 2014-09-21 07:31:10
            [assessment_id] => 1
            [supervisor_approval] => 1
            [manager_approval_date] => 2014-09-21 07:31:27
            [mainmanger] => 3
        )

    [1] => stdClass Object
        (
            [first_name] => test
            [last_name] => test
            [title] => test
            [id] => 34
            [type] => 4
            [manager] => 4
            [email] => p@yahoo.com
            [date] => 2014-09-20 07:39:55
            [status] => 2
            [approval_date] => 2014-09-20 07:40:41
            [assessment_id] => 3
            [supervisor_approval] => 1
            [manager_approval_date] => 2014-09-20 07:41:07
            [mainmanger] => 3
        )

    [2] => stdClass Object
        (
            [first_name] => jimmy john john
            [last_name] => john
            [title] => Lorad and Master
            [id] => 32
            [type] => 4
            [manager] => 3
            [email] => j@j.com
            [date] => 2014-09-21 07:38:50
            [status] => 2
            [approval_date] => 2014-09-19 07:39:25
            [assessment_id] => 2
            [supervisor_approval] => 1
            [manager_approval_date] => 2014-09-19 07:39:25
            [mainmanger] => 0
        )

)

Where "id" = the user ID.    If there are two or more entries for a user, I want to remove all but the most recent by the "approval_date",... So for the above example it would return:

Array

    [0] => stdClass Object
        (

            [last_name] => test
            [title] => test
            [id] => 34
            [type] => 4
            [manager] => 4
            [email] => piznac@yahoo.com
            [date] => 2014-09-21 07:23:12
            [status] => 2
            [approval_date] => 2014-09-21 07:31:10
            [assessment_id] => 1
            [supervisor_approval] => 1
            [manager_approval_date] => 2014-09-21 07:31:27
            [mainmanger] => 3
        )

    [1] => stdClass Object
        (
            [first_name] => jimmy john john
            [last_name] => john
            [title] => Lorad and Master
            [id] => 32
            [type] => 4
            [manager] => 3
            [email] => j@j.com
            [date] => 2014-09-21 07:38:50
            [status] => 2
            [approval_date] => 2014-09-19 07:39:25
            [assessment_id] => 2
            [supervisor_approval] => 1
            [manager_approval_date] => 2014-09-19 07:39:25
            [mainmanger] => 0
        )

)

I'm having a hard time wrapping my head around this concept, so I don't have any example code. And I don't really need or expect someone to code this for me,. just a push in the right direction would be awesome.

Hey guys,

I have got some events, and got it sorted by date, although at the moment the oldest date is showing first, and I would like to turn that around(new first old last), any simple suggestions?

Also another little question how would I turn a date row (for example 2009/5/31) into Tuesday - May 2009 or something similar, anyone can point me into the right direction?

{
$branch=$_POST['branch'];
$leavemonth=$_POST['leavemonth'];
$leaveyear=$_POST['leaveyear'];
}
