[SOLVED] sort array

[newb]

im trying to sort this array desc by the date but its not working for some reason. doesnt sort at all. here is this the code:

 

		$new_array = array(
		file => $file,
		date => $date
		);
		krsort( $new_array['date'] );
		echo $new_array['date'];

what are $file and $date set to, could you post that code too?

[newb]

$file = readdir("/public_html/");

$date = date("F d Y H:i:s.",filemtime("$file"));

[fooDigi]

you must be looping and other things besides just the code you provided... are you opening the dir and setting the handle first, etc? if so, post some more code...

ksort is sorting by key.

 

The key your sorting by is 'date', so everything you compare is the same. You want to sort by the value of the array key 'date'

check out that example

 

Personally I'd do the following....

 

$date = filemtime("$file");

 

Just add the timestamp. Sort the date on output.

 

Instead of ksort do the following;

 

<?php
array_multisort($new_array['date'], SORT_DESC, SORT_NUMERIC, $new_array['file']);
