Need help with complex array counting

I'm having an incredibly hard time trying to solve this problem... I have an array similar to the following:

[area1] => Array
        (
            [subarea1] => Array
                (
                    [subsubarea1] => Array
                        (
                            [0] => file1.txt
                            [1] => file2.pdf
                        )

                    [0] => blah1.txt
                    [1] => blah.2.txt
                    [2] => etc.mp3
                )

            [subarea2] => Array
                (
                    [subsubarea2.1] => Array
                        (
                            [0] => blah.txt
                        )

                    [subsubarea2.1] => Array
                        (
                            [0] => file1.txt
                            [1] => file2.pdf
                            [2] => file3.mpg
                        )

                )

        )

 

And I need to go through and count all the files (The [ #]s) in each of the sub arrays... But heres the problem - I need to track how many files are in each folder, and all folders underneath it.

Basically, what it boils down to - is I need to find out how many files are in any given folder, including all of it's sub folders - so I can let the user know how many files are in a folder (Obviously).

If anyone can think of a way to cycle through the array and get my answer - that'd be great... If you can think of another, better way to find out how many files are in a folder, and all of it's child folders, then that'd be better :)

 

Thanks in advanced to anyone who saves me the extra few hours of pulling my hair out... I really hate working with filesystems.

How about this:

 

<?php
function no_of_files($start_dir,$sub_dir=FALSE){
    $no_of_files=0;
    if($sub_dir === false){
        $handler = opendir($start_dir);	
    }else{
        $start_dir = $start_dir.$sub_dir;
        $handler = opendir($start_dir);
    }

    while(false !== ($file = readdir($handler))){
        if($file != '.' && $file != '..'){
            if(is_dir($start_dir.'\\'.$file)){//if this is a directory, recall the function with the subdirectory defined
                $dir_name = '\\'.$file;
                echo $dir_name.'<br />';
                $no_of_files += no_of_files($start_dir,$dir_name);	
            }else{//is a file, so increase our counter
                $no_of_files++;	
            }	
        }
    }
    return $no_of_files;
}
echo no_of_files('C:\Documents and Settings\Ben\My Documents\My Music');
?>

 

I made it for a post a while back. Counts the number of files in any directory and all sub directories.

In response to your original question of counting the number of elements within your multidimension array, this should work:

 

<?php
$array = array(1,2,array(1,2,3,array(1,2,3)),3,4,array(array(array(1,2))));
echo '<pre>';
print_r($array);
echo '</pre>';
function count_array($array){
	$num = 0;
foreach($array as $v){
	if(is_array($v)){
		$num += count_array($v);
	}else{
		$num++;
	}
}
return $num;
}
echo 'number of items in your array: '.count_array($array);
?>
