Question

Using the below action I gather a list of files and display them. I need to be able to sort the files by last modified date. Is there a simple way in PHP or using ZEND to order the items by last modified? If you know of a easier way to get the files and order them using ZEND; please let me know.

public function imagesAction()
{
    $this->_helper->layout->disableLayout();

    $results = array();

    $handler = opendir(APPLICATION_PATH . '/../public/images/blog');

    while ($file = readdir($handler)) {
        if ($file != "." && $file != ".." && $file != '.svn') {
            $results[] = $file;
        }
    }

    closedir($handler);

    $this->view->data = $results;
}

I have tried doing

$this->view->data = ksort($results);
$this->view->data = asort($results);

But those just remove the entire list of files from the view and they stop showing up.

public function imagesAction()

    $this->_helper->layout->disableLayout();

    $results = array();

    $handler = opendir(APPLICATION_PATH . '/../public/images/blog');

    while ($file = readdir($handler)) {
        if ($file != "." && $file != ".." && $file != '.svn') {
            $results[] = array('file' => $file, 'time' => filemtime($file));
        }
    }

    closedir($handler);

    uasort($results, function($file1, $file2) {
        if ( $file1['time'] == $file2['time'] )
           return 0;
        return $file1['time'] < $file2['time'] ? -1 : 1;
    });

    $this->view->data = $results;
}
