why I cannot remove directory?

[alan123]

I try to delete directory with php code:

unlink("$dir/.");
rmdir("$dir");

unlink is supposed to delete all files under $dir folder, but it gives me error message "permission denied", actually I created $dir and its files within the same php file:

mkdir("$dir", 0755);
copy("abc.htm", "$dir/abc.htm");
chmod("$dir/abc.htm",0755);

why I cannot delete files with the same user privilege? can anyone help me? thanks.

I don't think that unlink("$dir/."); removes the files. There's no wildcard here. If there are still files then rmdir($dir) will fail.
You need not doublequote the variable if no string parts are added.

Thanks for the reply.
So how can I remove all files under $dir folder (even includes .htaccess file)?

You will have to delete *.* and .* to cover all the files. .* might give you an error message as the directory entries . and .. cannot be removed.
Another way is to individually delete each file - there are several examples for recursive deletion in the HP manual:
