PHP - Check if a file exists in a folder

I wanna check if there any image on a folder from my server. I have this little function in PHP but is not working and I don't know why:

$path = 'folder/'.$id;
function check($path) {
    if ($handle = opendir($path)) {
        $array = array();
        while (false !== ($file = readdir($handle))) {
            if ($file != "." && $file != ".." && count > 2) {
                echo "folder not empty";
            } else {
                echo "folder empty";
            }
        }
    }
    closedir($handle);
}

Any help will be appreciated, thanks in advance.

Step 1: $query = select * from your_table where id=$id;
Step 2: $path=$query['path_column'];
Step 3: if($path!=null&&file_exit($path)&&$dir=opendir($path)){
           while (($file = readdir($dir )) !== false)
            {
                if ($file == '.' || $file == '..') 
                {
                    continue;
                }
                if($file) // file get 
                { 
                    $allowedExts = array("jpg");
                    $extension = pathinfo($file, PATHINFO_EXTENSION);
                    if(in_array($extension, $allowedExts))
                    $file[]=$file;
                }
                $data[file_name'] = $file;
            }
             closedir($dir);
        }

Try This:

$path = 'folder/'.$id;
function check($path) {
    if (is_dir($path)) {
        $contents = scandir($path);
        if(count($contents) > 2) {
            echo "folder not empty";
        } else {
            echo "folder empty";
        }
    }
    closedir($handle);
}

It counts the contents of the path. If there are more than two items, then its not empty. The two items we are ignoring are "." and "..".

It does not work because count is coming from nowhere. Try this instead:

$path = 'folder/'.$id;
function check($path) {
    $files = glob($path.'/*');
    echo empty($files) ? "$path is empty" : "$path is not empty";
}
