read images from directory

hi,

I've got this piece of coding which displays the images within a folder and allows me to add captions to the images using xml. the problem im having is once it reads the folder it is mixing the images up....instead of listing them in order like 1,2,3,4,5 it starts with 1 and then any number will follow. how can i stop it from doing this.

here is the code

how do you determine $item? as it looks, you're displaying the images in the order of the array. maybe some of the array sorting functions will help you.

ok asort() & ksort() seems to be a good and simple choice...from my coding which do i add asort() to?

asort($path.$it em[$n]); or asort($item[$n]); ?
ksort($path.$it em[$n]); or ksort($item[$n]); ?

@anfetienne
as described in the manual entry, asort() expects an array as input. thus
Expand|Select|Wrap|Line Numbers
  1. asort($item);

@anfetienne
well, ksort() will sort your array keys, which are already ordered, so it should not have any effect.

@anfetienne
see post above

except that "correct order" is very hard to teach a computer. do a var_dump() before and after sorting, so that you see how the sorting function actually sorts.
