trouble with Natsort function

[Anon]

I am trying to display files in a sorted order from a directory, i have used the opendir() and readdir().

These files are numerically numbered 1.jpg to 150.jpg, when I use the sort() function, i get 1.jpg 10.jpg 11.jpg 12.jpg...etc..

When I try to use natsort() nothing happends, the files are displayed in the same order as if I had no sort at all.

Thanks

post the code

here's the portion of the code:

$stack = array ();
$handle=opendir('/www/htdocs/images/gallery/thumbnail');
while (false!==($file = readdir($handle))) {
if (!is_dir($file)) {
array_push ($stack, $file);
}
}
closedir($handle);
natsort($stack);
$numimages = count($stack);

Theres more to this code but after this I am basically using a for $i = 1 to $numimages and displaying $stack[$i]

Thanks,

Mike

You'll see in the examples in the manual that natsort() sorts the array indices as well, so that if $stack[4]='23.jpg' before the natsort, $stack[4]=23.jpg' afterwards. Funny that, the docs themselves say otherwise - 'snot a bug, 'sa feature!

This illustrates a workaround:

$stack = array();
$handle=opendir('C:\tmp\');
while (false!==($file = readdir($handle))) {
if (!is_dir($file)) {
$stack[]=$file;
}
}
closedir($handle);

print_r($stack); // Before sorting - filesystem order

natsort($stack);

print_r($stack); // After sorting - jumbled indices

$stack=array_values($stack);

print_r($stack); // After sorting - reindexed.

foreach($stack as $file)
{ echo $file.'<br>';
}
