PHP directory recursion weirdness

[Malcolm]

I wrote a function that recursively grabs a directory tree.

Here my directory structure:

/
/directory
/directory/sub-dir
/directory/sub-dir/sub-sub-dir
/new1
/new2
/new2/new3
/new2/new4
/new2/new5
/new2/new5/new6

This is my code:

/*function: list_tree()
VARS:
$dir = start path
$level = how deep the dir is in the tree (recursive entry only)
*/
function list_tree($dir, $level=0)
{
    // Define Arrays
    $rec = array();
    $dirs = array();
    
    if (is_dir($dir)){
        if ($dh = opendir($dir)) {
            while (($file = readdir($dh)) !== false) {
                if(!preg_match("#\.#", $file) && is_dir($dir . "/" . $file) && !is_file($dir . "/" . $file) && !is_link($dir . "/" . $file)){
                    $dirs[] = $dir . "/" . $file."&".$level;
                    $rec = list_tree($dir . "/" . $file, $level+1);
                }//end:if
                for($x = 0; $x < sizeof($rec); $x++){
                    $dirs[] = $rec[$x];
                }//end:for
            }//end:while
            closedir($dh);
        }//end:if
    }//end:if
    return $dirs;
}//end:functions 

With this code I should see

directory&1
sub-dir&2
sub-sub-dir&3
new1&1
new2&1
new3&2
new4&4
new5&4
new6&5

But what i get is

directory&1

and

sub-dir&2
sub-sub-dir&3
sub-sub-dir&3
sub-sub-dir&3

repeated 7 times, then the other right stuff.

Any idea whats going on?

Get an answer, just had to replace my for loop with a array_merge.
Incase anyone wants the full code for their own use:

function list_tree($dir, $level=0) 
{ 
    // Define Arrays
    $rec = array(); 
    $dirs = array(); 

    if (is_dir($dir)){ 
        if ($dh = opendir($dir)) { 
            while (($file = readdir($dh)) !== false) { 
                if (is_dir($dir . '/' . $file) 
                     && !is_link($dir . '/' . $file)
                     && ($file != '.') 
                     && ($file != '..')) {
                    $dirs[] = $dir . "/" . $file."&".$level; 
                    $rec = list_tree($dir . "/" . $file, $level+1); 
                    $dirs = array_merge($dirs, $rec);
                }//end:if
            }//end:while
            closedir($dh); 
        }//end:if
    }//end:if
    return $dirs; 
}//end:functions

Oh yeah, was just about to give you the solutions.
