ID: 28156 Updated by: helly@php.net Reported By: info at gramba dot tv -Status: Open +Status: Suspended Bug Type: Feature/Change Request -Operating System: debian +Operating System: * -PHP Version: 5CVS-2004-04-26 (dev) +PHP Version: 5.0.0.0 -Assigned To: +Assigned To: helly New Comment: We are considering a new operator or internal function to take care of this after PHP 5.0. A patch is here: http://marcus-boerger.de/php/ext/ze2/ze2-ifsetor-20040416-4.diff.txt Syntax: ifsetor( <var> [, <exp> ]) Semantic: check whether variable <var> exists and return it. If it not exists evaluate expression <exp> which defaults to NULL and return that value instead. Comment: <var> may also be an array subscription of any depth.
