scandir to only show folders, not files

Question

I have a bit of PHP used to pulled a list of files from my image directory - it's used in a form to select where an uploaded image will be saved. Below is the code:

$files = array_map("htmlspecialchars", scandir("../images"));       

foreach ($files as $file) {
 $filelist .= sprintf('<option value="%s">%s</option>' . PHP_EOL, $file, $file );
}

It works fine but shows all files and folders in 'images', does someone know a way to modify this code so that it only shows folder names found in the 'images' folder, not any other files.

Thanks

Answer 1

The easiest and quickest will be glob with GLOB_ONLYDIR flag:

foreach(glob('../images/*', GLOB_ONLYDIR) as $dir) {
    $dirname = basename($dir);
}

Answer 2

Function is_dir() is the solution :

foreach ($files as $file) {

  if(is_dir($file) and $file != "." && $file != "..") $filelist .= sprintf('<option value="%s">%s</option>' . PHP_EOL, $file, $file );

}

Answer 3

The is_dir() function requires an absolute path to the item that it is checking.

$base_dir    = get_home_path() . '/downloads'; 
//get_home_path() is a wordpress function
$sub_dirs = array();
$dir_to_check = scandir($dir);
foreach ($dir_to_check as $item){
  if ($item != '..' && $item != '.' && is_dir($base_dir . "/" . $item)){
    array_push($sub_dirs, $item);
  }
}

Answer 4

You could just use your array_map function combined with glob

$folders = array_map(function($dir) {
    return basename($dir);
}, glob('../images/*', GLOB_ONLYDIR));

Yes, I copied a part of it of dev-null-dweller , but I find my solution a bit more re-useable.

I try this

    <?php

$dir = "../";

$a = array_map("htmlspecialchars", scandir($dir));

$no = 0; foreach ($a as $file) {

  if ( strpos($file, ".") == null && $file !== "." && $file !== ".." ) {
    $filelist[$no] = $file; $no ++;
  }

}
print_r($filelist);
?>
