Req #10527 [Opn->Wfx]: Declare constant variables

Edit report at https://bugs.php.net/bug.php?id=10527&edit=1 ID: 10527 Updated by: krakjoe@php.net Reported by: jnutzman at yahoo dot com Summary: Declare constant variables -Status: Open +Status: Wont fix Type: Feature/Change Request Package: Scripting Engine problem Operating System: * PHP Version: * Block user comment: N Private report: N New Comment: I don't think a constant variable makes sense in principle. We don't have the concept of a symbol in user land PHP. In C (or others), where everything is a symbol, functions, classes, named variables, it makes sense for a symbol to be constant. In PHP, we don't have symbols, we have constants, variables, classes, and functions, they are distinct and non-overlapping. To change this would be a significant and complicated change, of the kind that requires and RFC. I'm therefore going to mark this bug as won't fix, it can still be found if some future RFC requires it for reference. Sorry about the wait :) Previous Comments: ------------------------------------------------------------------------ [2001-04-27 12:37:44] jnutzman at yahoo dot com PHP 4 doesn't seem to have the capability to define variables of all types as being constants. An example of this could be: $stuff = (const)array('1','2'); or $stuff = const($stuff); An error would be generated if the script later tried to: $stuff = array('3','2'); This is *not* the same as CONSTANTS like TRUE and FALSE. This would be extremely useful with sessions, so other programmers don't clobber important session variables that shouldn't change. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=10527&edit=1
