Remove directory recursively

Hi all,

I have a problem with a function I got from PHP.net. The function deletes the files in a directory then deletes the empty directory. My problem is that I sometimes have directories 2-levels deep and wants to delete all files and folders from a selected directory and this function will return me an object error when I do so.

Here's the function:-


function removedirR($conn,$dirName){

$ar_files = ftp_nlist($conn, $dirName);
if (is_array($ar_files)){
for ($i=0;$i<count($ar_files);$i++){
$st_file = $ar_files[$i];
if (ftp_size($conn, $st_file) == -1){
$this->removedirR( $st_file);
} else {
ftp_delete($conn, $st_file);
}
}
}
if (ftp_rmdir($conn, $dirName))
return true;
}



Can someone points me in the correct direction? I attempted using ftp_res but I'm stuck on where to add the check into the above function.

thanks.

I've managed to get the above function to recursively delete directories and files within.

Can someone tell me if
(ftp_size($conn, $st_file) == -1) is a check on whether the said file is a directory? Coz I tried on one server and it actually tried to delete files when it should have deleted the directory, I got the no such directory error.

Another server I tried, had no such problem and I could delete folders, files etc fine. Is there any additional validation I can do to check the array item whether its a file or a directory?
