Question

I am trying to make a function that scans a folder for subfolders and then returns
a numeric array with the names of those folders.

This is the code i use for testing. Once i get it to print out the folder names and not just “.” and “..” for present and above folder all will be well, and I can finish the function.

<?php
function super_l_getthemes($dir="themes")
{

if ($handle = opendir($dir)) {
    echo "Handle: {$handle}\n";
    echo "Files:\n";


    while (false !== ($file = readdir($handle))) {
       echo "{$file}<br>";
    }

    closedir($handle);
}
?>

The above code works fine, and prints out all the contents of the folder: files, subfolders and the “.” and “..”

but if i replace:

  while (false !== ($file = readdir($handle))) {
       echo "{$file}<br>";
    }

with:

while (false !== ($file = readdir($handle))) {
        if(file_exists($file) && is_dir($file)){echo "{$file}";}
    }

The function only prints “.” and “..” , not the two folder names that I’d like it to print.

Any help is appreciated.

You must provide the absolute path to file_exists, otherwise it will look for it in the current execution path.

while (false !== ($file = readdir($handle))) {
    $file_path = $dir . DIRECTORY_SEPARATOR . $file;
    if (file_exists($file_path) && is_dir($file_path)) {
        echo "{$file}";
    }
}
