Error with is_array

[kumschick]

$rootpath="c:";
if(empty($path)) { $rootdir="$rootpath"; } else { $rootdir="$path"; }


  if($handle = opendir("$rootdir")) $i=0; {
  if(is_array("$handle")) { echo"yes - $handle"; } else { echo"no - $handle"; }  

   while (false !== ($filename = readdir($handle))) { 
     $i++;

   if(is_array("$handle")) {
     echo"yes - $handle";
   }
   else {
     echo"no - $handle";
   }

     .....
     .....

 }
 }

Result: no - Resource id #1no - Resource id #1

I want to make a asort or arsort, etc...!
But it doesnt' work

The reason is that opendir() returns a resource, not an array.
The array is built by looping through the directory.

$rootpath = "c:";
if (empty($path)) {
	$rootdir = $rootpath;
} else {
	$rootdir = $path;
}

$file_array = array();
if (is_dir($rootdir)) {
	if (($handle = opendir($rootdir)) !== false) {
		while (($filename = readdir($handle)) !== false) {
			if ($filename != '.' && $filename != '..') {
				$file_array[] = $filename;
			}
		}
	} else {
		echo "'" . $rootdir . "' could not be opened";
	}
} else {
	echo "'" . $rootdir . "' is not a directory";
}

//now sort $file_array
