#50068 [Opn]: const problem

ID: 50068 Updated by: ksingla@php.net Reported By: jachym dot tousek at gmail dot com Status: Open Bug Type: Scripting Engine problem Operating System: Windows 7 PHP Version: 5.3.1RC3 New Comment: I think this behavior is by design. const expressions are evaluated at compile time. So only few operations are supported in a const expression and string concatenation is not one of those. I could repro this in PHP 5.2 (after putting it under a class).
