Problem with class remembering data when used the second time - El Forum - 06-03-2008
[eluser]floweringmind88[/eluser]
My class is a library and it works great the first time I use it in my controller. But if I use it a second time in my controller it remembers the data from the previous use causing the wrong output of data.
How do I reuse the class without having it store the data?

Do you mind showing us some code?
How are the data "stored" in your library?

The class uses arrays and I imagine that is what isn't being reset.

Nevermind I figured out what arrays weren't being reset.

Don't you have to initialize $values before passing it to
Code:
$ok = xml_parse_into_struct($parser, $data, $values);
