Self nested function returns cgi error

[sachavdk]

Hi,

I'm trying to write a function that loops through a folder I specify,
if a specific file is also a folder, the function itself is called again with the new directory path,
it loops through this one, ...

But the error I get is:
[b]The specified CGI application misbehaved by not returning a complete set of HTTP headers. The headers it did return are:[/b]
(No headers are sent with it).
Here's the function (var $tpls is not used yet but I don't think that'll be the problem):
[b]$tpls = "";
$dir = "styles/main/tpl/";
function loopDirs($dir, $tpls) {
if (is_dir($dir)) {
if ($dh = opendir($dir)) {
while (($file = readdir($dh)) !== false) {
if (is_dir($dir . "/" . $file . "/")) {
loopDirs($dir . "/" . $file . "/", $tpls);
}
else {
echo $dir . "/" . $file."<br />";
}
}
closedir($dh);
}
}
}
loopDirs($dir, $tpls);[/b]

Sorry for posting that quick, I had to search better.
The error is caused because I don't check for . and ..
So it gets in an never ending loop.

Maybe something to check for people who have the same prob. :P  ;D
