PHP Script To Count Folders?

[mossc001]

I have be looking through the internet for a PHP script which counts the number of folders in a given directory but can't find a thing.

Does anyone know of a small script that could be used to count folders and display the output?

<?
$dir="folder/"

Something.....??????

?>

<?php
//Number of folders

echo "Total Folders: ".$totalnofolders."";

?>

Any help would be much appreciated.
Cheers

If your version of PHP is 4.3.3 or greater, or if you are running any recent version of PHP on an operating system that uses the GNU C library:

<?php
$a = count(glob('folder/*', GLOB_ONLYDIR));
print $a;
?>

Brilliant!

That is so simple, I don't know why I didn't think of it.

Have you looked at opendir() in The php.net online manual

Of the top of my head it would be something like:

function count_dirs($path){
//check that $dir really exists
    if(is_dir($path)){
//initialize counter
    $num_dirs="0";
//Open Dir to parse
    if ($dh = opendir($path))
    {
        //begin loop to read directory
        while (($objectindir = readdir($dh)) !== false){
            //discard . and .. directory pointers
             if (($objectindir != ".") && ($objectindir != ".."))
             {
		if(isdir($objectindir))
		{
			//check if name is a dir and increase counter
			$num_dirs++;             
		}

             }//if . and ..
          }//while
    }
    closedir($dh);

return $num_dirs;
}

Notice: this is off the top of my head it could have and most likely does have some errors.
