Invalid argument supplied for foreach() - using glob

Question

Today i have a problem with my script, my script should search for (.css files)

I\'ve used a code to:

1. Search for all subfolders in a root folder

Answer 1

Change this:

$path[] = $dir;
foreach($path as $dirname){
    $add = glob($dirname . '/*.css');
    foreach($add as $file){

to this:

$path[] = $dir;
var_dump($path);
foreach($path as $dirname){
    $add = glob($dirname . '/*.css');
    var_dump($add);
    foreach($add as $file){

We don't know which line 131 is, so I don't know which foreach fails.

(I'm guessing the 2nd, because the first is practically forced to array by $path[] = ..)
