[SOLVED] opendir/readdir order

[fanfavorite]

I use the opendir/readdir commands to read through and display all the images in a directory or multiple directories.  What I am trying to do is say I have 200 images in the directory, I want to display 50 on a page and use previous and next buttons.  The problem is that readdir seems to be in no particular order.  Is there a way to force an order or so that I can split them properly?

Hi mate

You can try with scandir method which second parameter is used for sorting order.

For more info you can visit this page : http://www.php.net/manual/en/function.scandir.php.

You could try readdir once, cache the result in a sorted, serialized array in a session or flat file, and paginate through the cached array. That would eliminate extra I/O seeks, and would preserver order.

thanks guys, both seem like they will work. Will give it a try.
