Recursive directory listing

[furious5]

Can anyone help me out, I posted a message about directory listing a week ago and have done a little bit more work on it.

Basically I want to only list named directories and display an image if a specified image is found.

When I've ran the code, it doesn't seem to like it when I use if(file_exists)

I have used if(!file_exists) to test it out and it displays the images properly so it is nothing to do with paths etc.

Anyone any ideas, or suggestions to tidy my code up?

// Open a known directory, and proceed to read its contents
if (is_dir($dir)) {
if ($dh = opendir($dir)) {
while (($file = readdir($dh)) !== false) {

		$test = filetype($dir . $file);

		if($test == "dir") # check it is a directory
			if(($file != ".") && ($file != "..")){  # do not list the base directory elements

				$image = strtolower($file)."_main.jpg"; # convert file to lowercase and append to image variable

				if(file_exists($image)){ # check if a main image exists, if so display the directory
					echo "<img src=media/pics/".$name."/".$file."/".$image. ">";
					echo $file ."<br>";
				} else {
					echo "no match";
				}
			}
		}

   }
   closedir($dh);

}

How does the code not work?
Saying something vague like "it doesn't seem to like it" is something that many people do not seem to like.

That said, using strtolower() like that isnt a good idea.
You should just store all the filenames in lower case to begin with.

Sorry laserlight, it wasn't very descriptive.

When I say the code isn't working, what I mean is that the code doesn't seem to want to run when I use if(file_exists) and simply prints out no match as displayed in the else statement.

I have checked the files and ensured they are correctly named.

If I run the query in reverse, using !file_exists, the code executes and displays the images correctly. I was just trying to see what was causing the problem.

The only reason I am using strtolower is convert the name of the directory to lower case as this is used for display purposes as well, but it would probably be easier to use a lowercase file name and convert the string to display properly at the browser.

I will have a look at this, and see if this resolves the problem.

Still no joy. I've amended the directory names etc.

The only thing I can think is that while the loop is iterating through the files, it is not actually updating the directory name hence it is not finding any of the files i.e it is purely checking for the files in the root of the dir.

Amended this and still no joy...
