Count array elements returned by scandir(); PHP

Question

I have in folder "files" some folders. I want to return the count of this folders by my php code:

$x = count(scandir('/files'));
echo $x;

But this is not working. What is wrong?

Answer 1

If you have some files in files folder, Here is the solution.

  $directory = 'files/';
  $scanned_directory = array_diff(scandir($directory), array('..', '.'));//to remove dots
  $x = count($scanned_directory);
  echo $x;

Try not to use /files. It will look for the file named files

Answer 2

Try this:

$directory = '/your/directory/path/';
$files = glob($directory . '*.*');   // returns an array on success and false on error.

if ( $files !== false )
{
    $filecount = count( $files );
    echo $filecount;
}
else
{
    echo 0;
}

Answer 3

its better to check if directory does even exist first :

$directory = '/your/directory/path/';
if(!is_dir($directory))
    die("direction not exists");

ant then count and remove . and .. elements
