[FIXED] Warning "Variable does not seem to be used in its scope" in foreach

Issue

I wrote a simple foreach to filter one array and write it's results to another array.

foreach ( $users as $user ) {
    ...
    $user_email_list[ ] = $user[ "intranet-id" ][ "value" ];
    ...
}

Problem is that NetBeans is showing me a warning "Variable does not seem to be used in its scope" on $user. If I try to initialize $user before foreach, no warning shows. However it doesn't seem to be right.

Is this a NetBeans bug or do I simply misunderstand anything?

I am using NetBeans version 6.7.1 (Build 200907230233) and PHP 5.2.10.

Solution

Netbeans might be getting it wrong - the code seems ok.
