Recursion through a directory tree in PHP

Question

I have a set of folders that has a depth of at least 4 or 5 levels. I'm looking to recurse through the directory tree as deep as it goes, and iterate over every file. I've gotten the code to go down into the first sets of subdirectories, but no deeper, and I'm not sure why. Any ideas?

$count = 0;
$dir = "/Applications/MAMP/htdocs/site.com";
function recurseDirs($main, $count){
    $dir = "/Applications/MAMP/htdocs/site.com";
    $dirHandle = opendir($main);
    echo "here";
    while($file = readdir($dirHandle)){
        if(is_dir($file) && $file != '.' && $file != '..'){
            echo "isdir";
            recurseDirs($file);
        }
        else{
            $count++;
            echo "$count: filename: $file in $dir/$main \n<br />";
        }
    }
}
recurseDirs($dir, $count);

Check out the new RecursiveDirectoryIterator.

It's still far from perfect as you can't order the search results and other things, but to simply get a list of files, it's fine.

There are simple examples to get you started in the manual like this one:

<?php

$path = realpath('/etc');

$objects = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path), 
RecursiveIteratorIterator::SELF_FIRST);

foreach($objects as $name => $object){
    echo "$name\n";
}

?>
