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

I found the same issue with a PHP script today and it took switching from a foreach loop to a for loop to fix it. Not sure what means, the array looks and works the same.

// Errors out
$files = glob($directory.'*.html');
foreach($files as $file){
    echo($file);
}

// No error
$files = glob($directory.'*.html');
for($i=0; $i
