Question

I’ve been using the following snippet to include multiple files:

foreach(glob(APP_PATH."libs/*.php") as $path)
{
 include $path;
}

The thing is, I don’t want to have the $path variable available inside the included files.

---

Fictitious solution:

include unset($path);

This would have worked if unset returned the value of the unsetted variable. It doesn’t though. It returns void.

Answer 1

You could write your own unset that returns the value…

function unsetr(&$value) {
    $result = $value;
    unset($value);
    return $result;
}
