things are not going into array correctly

I have a script that pulls files from a directory and places the file names into an array. The files are named as 001.jpg, 002.jpg, 003.jpg, etc.

 

The problem is that the files aren't being placed into the array in an orderly way. For example, 409.jpg could be placed in element zero when really 001.jpg should be placed there. How do I fix this? Here is my code:

 

$pics = array();
if ($handle = opendir($dir)) {
while (false !== ($file = readdir($handle))) {
	if ($file != "." && $file != ".." && $file != "Thumbs.db" && $file != "main.jpg") {
		array_push($pics, $file);
	}
}
}

Looks like I found the answer to my own problem. I used the sort() function.

 

sort($pics);

Or even use scandir() instead

Or glob().  glob() is really one of the cleanest directory traversal solutions.
