counting directories and subdirectories (no files)

[Phoenix_Down]

How is it possible to count all the directories and subdirectories, but no files?

You can check if a filename is a directory or not using is_dir

I know, but how do I count the dirs?

[future448]

Well where have you got to so far?

You open the directory with opendir()

Get the contents with readdir()

Check if its a directory with is_dir()

So you could do something like this:

<?php
$dir = '' // the directory
$num_dirs = 0;

  if ($dir = opendir($dir))
            {
                while (($file = readdir($dir)) !== false)
                {
                    if(is_dir($file) AND $file != "." AND $file != "..")
                    {
                        $num_dirs++;
                    }
                }  

                closedir($dir);    

                $total = $num_dirs;
            }
?>

You need a recursive function like this...

<?php
function dirCount($strDir){
	$intNB	= 0;
	$strDir	= str_replace('\\', '/', $strDir);
	$strDir	= rtrim($strDir, '/');
	$resDir	= opendir($strDir);
	while(($strFile = readdir($resDir)) !==false) {
		if(($strFile <> '.') && ($strFile <> '..') && is_dir($strDir . '/' . $strFile)) {
			$intNB++;
			$intNB	+= dirCount($strDir . '/' . $strFile);
		}
	}
	return $intNB;
}
echo dirCount('/home'); // just an example
?>

You might find it useful to use [man]glob/man with the GLOB_ONLYDIR option, rather than the opendir()/readdir()/is_dir() combination.
