im using this code to read from a directory and display images from it, i just want to know if theres any way i can make it display the images in a different order, it defaults to alphabetical order, but id like to change it, anyone know how?

  $mydir = dir('gallery/tn/');
 while(($file = $mydir->read()) !== false) {
  if ($file == "."|| $file == ".."|| $file == "Thumbs.db"){}
	  else {
	  echo ("<a href='gallery.php?pic=$file'><img border='0' src='gallery/tn/$file' alt='' /></a>");
	  }
  }
 $mydir->close();

What type of order are you looking for? The default way is alphabetical order of course, that is because thats how the server reads any directory.

if possible id like a 'last modified' order, though im not sure if that is possible. when i add pictures to the directory id like them to be displayed first.

i suppose i could just name them in a chronological order, but thats no fun!


edit: ok say i have all the pictures named 1.jpg, 2.jpg etc how would i get it to display them with the biggest number first i.e. 10.jpg, 9,jpg,8.jpg and so on

You could probably create a function to sort the files from 10 =< 1 If you search 'sorting files' on php.net you get a whole list of results and some code snippets other than that I'm not sure.. I'll write some code see what I can do

OK..
This is what I got

	 <?php
		 $myfile = dir('../NonBlog/count/');
		 $files = array();
		 $i = 0;
		 while (($file = $myfile->read()) != false) {
			 if ($file == '.' || $file == '..') {}
			 else {
				 $files[$i] = $file;
				 rsort($files);
				 $filecount = count($files);
				 while($i < $filecount) { 
					echo '../' . $files[$i] . '<br />';
					$i++;
				 }
			 }
		 }
		 $myfile->close();
		 ?>

Unfortunatley The Output I got was

Quote

../3.txt
../3.txt
../2.txt
../2.txt
../1.txt
../1.txt

I put 6 text files in a folder called count but it repeated the first 3 2x each so if anyone can find the bug post it
P.S. I hoped this helped if not then sorry !

		 while (($file = $myfile->read()) != false) {
			 if ($file != '.' || $file != '..'){
				 $files[$i] = $file;
			 }
		 }

		 $filecount = count($files);
		 while($i < $filecount) { 
			 echo $files[$i] . '<br />';
			 $i++;
		 }

With any luck, that should work a little better. You should note how i removed the else statement since it will make things look a little cleaner.

And, if you want to sort by the modification time, i would look into the filemtime function, and change the above script to work with that.

note: To get the sort to work right, i would store the modification times of the files into an array, with the filename as the key.
i.e.

$list[filemtime($file[$i]] = $file[$i];

You can refer to php.net for more info on the thousands of sort functions they have (the correct one for this would be asort() i believe).
