I actually had `fclose` the first time I wrote this code. It makes sense, after all, that if I `fopen` the file resource, I must `fclose` it when I'm done using it. Well, it doesn't work! Here's the error:

```
PHP Warning:  fclose(): 93 is not a valid stream resource in /Users/shau7246/development/personal/php-opencloud/samples/ObjectStore/auto-extract-archive-files.php on line 48

```

This led me to believe that the file resource was already being `fclose`'d by some function in the call stack. So I left it out of my code.

I don't like it but I'm not sure what else to do.
