Identifying if file is a directory

PHP
1

I am building a local filing system on my localhost.

I can display all of the files and can link to the files, but I want to identify if a file is a directory so I can apply a special link to it. SO…

 <?php

$dir = "something/afolder/"

$filenamejj = $dirArray[$index];
	$isdir = is_dir($dir);
		if($isdir) {
		$ext = end(explode('.', $filenamejj));
		print("<TR><TD><a href='filer.php?dir=$dir/$filenamejj'>$dirArray[$index]</a></td><td>Directory</td>");
		} else {
		$ext = end(explode('.', $filenamejj));
		print("<TR><TD><a href='openfile.php?$dir/$filenamejj'>$dirArray[$index]</a></td><td>$ext</td>");
		}
		
		print("</TR>\
");

This is just a snippet which is the conditional statement to decide whether it is a directory or not. For some reason, it always says that the files are not directories, even when I know when one isn’t.

If anyone could help me that would be great thanks!

First of all, what does file_exists($dir) come up with?
