Checking folder contents

How do I do this in php: retrieve the number of subfolders and their names inside a specified folder, as well as retrieve the number of files as well as their names in that subfolder. I'm making an image gallery for my brother.

 

Like this?

function dir_get_contents($dir)
{
	$dir = rtrim($dir, '/\\');

	if (!$handle = @opendir($dir))
	{
		trigger_error("Unable to open directory {$dir}");
		return false;
	}
	
	$files = array();
	
	while (($entry = readdir($handle)) !== false)
	{
		if (!in_array($entry, array('.', '..')))
		{
			$path = "{$dir}/{$entry}";
			
			if (is_file($path))
			{
				$files[] = $path;
			}
			else if (is_dir($path) AND $tmp = dir_get_contents($path))
			{
				$files = array_merge($files, $tmp);
			}
		}
	}

	closedir($handle);
	return $files;
}

Usage example:

$files = dir_get_contents('path/to/dir');

echo '<pre>' . print_r($files, true) . '</pre>';

Thanks a lot. I'll look it over and customize it for my project.
