Help with modifying pictures from folders.. prob easy solve.

[0o0o0]

heres the code im using on my page 2. Works great grabs all pics in all product folders.

$files = glob("./images/$code/*.*"); 
for ($i=0; $i<count($files); 
$i++) { $num = $files[$i]; 

Now on page one I just want the very first picture.. that will be a link to page 2 with all the pictures.

how do I modify this little code to only grab the first file in each folder. Kinda like how K I J J I Ji does it.. page 1 listings.. then page 2 which ive already finished.

I DO NOT KNOW THE FILE NAMES IN EVERY FOLDER.. I just first one.. or random one but just one.. for my page one.

I tried changing $i=0 to $i=1 that just loses a pic out of every folder.
thanks.

If you only want one of something then you don't need a loop for it.
See [man]array_shift[/man]. Don't forget to check that the array isn't [man]empty[/man] first.

I ended up with this.. seems to work.

$files = glob("./images/$code/*.*"); 
$i = rand(0, count($files)-1); 
$num = $files[$i];

Thanks for the reply.

Well, that won't give you the first picture, just any picture.
