PHP Array Sort

[whatever]

New to this forum so hope you can help me,

 

Before I pull my hair out here trying to get this to work, I was wondering can anyone see how come this isnt working.

 

The code creates thumbnails of pictures from the folder that it is in and displays them in a table which is 4 columns wide. At the moment the code seems to randomly pick files and place them in the html table.  I am looking to sort the files by name (all files have numbers at the end - picture01, picture 02 etc).

 

I placed sort($files) into the code just before the table is created and then the page layout is thrown out. It displays alot more than 4 pictures across the page. 

 

If anyone can see the problem It would be much appreciated.

 

Thanks

try asort()

[whatever]

hey

 

thanks for the quick reply, I tried asort and a few others that I got on php.net and the following display happens.

 

I would like the code to display the table correctly but sorted alphabetically if possible.

 

 

Thanks again

I'm sorry I really can't dig into your code right now someone else might be able to help *bump*
