Parent Dir Problemo!

[harris97]

I would like to create a script that could browse all the files (to open and modify them), even if they are in a sub-sub-sub directory.
The problem is that when i get to such a sub-sub-sub directory, i can\'t get back to the parent directory. example : i\'m entering direnctory subdirA-subdirB-subdirC. how to get back to subdirA-subdirB (up one level)

is there any idea or example script?.
Thanks alot!!

Search the forum, there are a few examples of how to recursively walk through a directory tree.

There might be some stuff left over from what I was using it for.

$MAX_DEPTH = 30;
$depth = 0;

function recurse($dir) {
global $depth, $MAX_DEPTH, $kbdir, $startdir, $q;

if(!$handle = opendir($dir)) {
	print "Directory read error: $dir\n";
	return;
}

if($depth++ > $MAX_DEPTH) {
	print "Too deep. Exiting...";
	exit;
}

while ($file_name = readdir($handle)) {
	if($file_name == "." || $file_name == ".." || $file_name == "CVS") {
		continue;
	}

	if(is_dir($dir . '/' . $file_name)) {
		recurse($dir . '/' . $file_name);
	}
	else {
		//do your stuff here
		}
	}
}

closedir($handle);
$depth--;

}
