From 4bdad7125a34e121f7857c34480d0527c1925384 Mon Sep 17 00:00:00 2001 From: Igor Wiedler Date: Wed, 13 Jul 2011 11:32:38 +0200 Subject: [ticket/9608] Remove use of references in captcha and other places References are not really needed in PHP due to copy-on-write. Since PHP5, objects are always passed around as identifiers, which means they are mutable. So it is no longer required to pass these by reference either.
