Sorting files by date.

[HomoErectus]

$image_dir './images/';
$images = glob($image_dir."*.jpg"));How can I sort the $images array so it has the most recently modified file in first place and least recently modified file in last place?

Build an array of files then sort the array using filemtime() (http://uk2.php.net/manual/en/function.filemtime.php)

Hello MrCod,

I already have the array of files retrieved using the above code. How would I sort it with filemtime?

Here's an example from the PHP docs, extended somewhat and using the pretty coding style that MrCoder likes and missed...

<?php
$arrDIR = array();
FOREACH (glob("*") as $filename) :
IF (is_file($filename)) : // if you want to omit directories
$arrDIR[$filename] = filemtime($filename);
ENDIF;
ENDFOREACH;
asort($arrDIR);
?>

Just like that but with {} :)

I would, (surprise, surprise) do it differently.$image_dir './images/';
$images = glob($image_dir."*.jpg"));Just add the following line after your code:array_multisort(array_map('filemtime', $images), SORT_DESC, $images);

So would I if performance was certain to never be an issue.

Most of these canned array functions are extremely slow.

I am getting following error

Warning: filemtime() [function.filemtime]: stat failed for...

The sorting code used
array_multisort(array_map('filemtime',$afiles),SORT_DESC,SORT_NUMERIC,$afiles);

Please support find the issue...

Thanks
