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
2. Make all paths of subfolders in an array
3. by using foreach(){glob….}, the script should found all paths of css files

Here is my code :

$path = '';
$stack[] = $dir;

while ($stack) {
    $thisdir = array_pop($stack);

    if ($dircont = scandir($thisdir)) {
        $i=0;

        while (isset($dircont[$i])) {
            if ($dircont[$i] !== '.' && $dircont[$i] !== '..') {
                $current_file = "{$thisdir}/{$dircont[$i]}";

                if (is_dir($current_file)) {
                    $path[] = "{$thisdir}/{$dircont[$i]}";
                    $stack[] = $current_file;
                }
            }
            $i++;
        }
    }
}

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

    foreach($add as $file){
        $code = file_get_contents($file);
        $code_arab = arabicer($code);
        file_put_contents($file,$code_arab);
    }
}

When i start my script i found an waning message:

Warning: Invalid argument supplied for foreach() in /home/u274517531/public_html/libs/functions.php on line 131

I’m sure my array is not empty.

So, anyone can help me how to solve this problem ?

Thanks.

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[] = ..)
