get files of a directory

Question

I'd like to get a list of files stored in a sub directory of the /media directory in a controller.

I tried to use this one:

$dir = Mage::getBaseDir('media') . DS . $sub_dir . DS;
$files = scandir($dir);

But the array $files is empty.

I tried something like that:

$file = new Varien_Io_File();
$dir = Mage::getBaseDir('media') . DS . $sub_dir . DS;
$file->ls($dir);

Magento says Unable to list current working directory.

Answer 1

scandir should at least return the current . and parent .. directory. Make sure the directory exists and check permissions. Are you sure $files is an array at all?

When using Varien_Io_File, the correct usage would be:

$file = new Varien_Io_File();
$dir = Mage::getBaseDir('media') . DS . $sub_dir . DS;
$file->open(array('path' => $dir));
$file->ls();

Answer 2

Use DirectoryIterator, then it works. Here's my code snippet:

$dir = new DirectoryIterator(Mage::getBaseDir('media') . DS .  $sub_dir . DS . $category . DS);
$extensions = "jpg|jpeg|png";
$images = array();

foreach ($dir as $fileinfo) {
    if ($fileinfo->isFile() && stristr($extensions, $fileinfo->getExtension())) {
        array_push($images, substr($fileinfo->getPathname(),strlen($_SERVER['DOCUMENT_ROOT'])));
    }               
}

return $images;

Hope this help anyone who has the same problem :-) Maybe it's not the "magento" way, but it works
