#23365 [Bgs->Opn]: global twice causes problems

ID: 23365 User updated by: spagmoid at yahoo dot com Reported By: spagmoid at yahoo dot com -Status: Bogus +Status: Open Bug Type: *General Issues Operating System: WinXP PHP Version: 4.3.1 New Comment: I used to give very specific repro's. Now I don't bother spending 15 minutes to be precise because someone always comes along and spends a total of 5 seconds before lazily marking things bogus. Maybe it's just with classes, maybe its something else. Suffice it to say, problems occur with global when they shouldn't. There's no reason to say: $A = 1; $A = 1; either is there? So if $A was 2 afterward, that wouldn't be a bug? There are valid reasons. Global should make something global period, not screw it up. My reason is, I am requiring a file in 2 different places, once in the global scope and once in a function. So I declare global $Object, and if we are already in the global scope things screw up. Now this is a bug. There are things called principles, like doing something the right way even when you don't readily see a reason for it. I still don't expect any action on this, but now whoever bogusifies it this time will at least have no Pontius Pilate excuse when you're brought before the God of programming.

Let's leave out for the moment the sheer wrongness of globalizing a variable twice in a row. That's not even at issue at the moment. What you descibe simply doesn't occur (in PHP4 or PHP5). It may be that there are special circumstances causing it to happen in your script but since you failed to follow the instructions on how to report a bug I'm simply writting my own script to test it. <?php function foo() { global $bar; global $bar; echo $bar; } $bar = "baz"; foo(); ?> Outputs "baz" as expected. If you decide to submit a proper bug report (with the minimally necessary information), please do so by reopening this bug with the updated information. NOT by creating a new bug. (Again, following instructions is a good thing) Oh, and on a personal note, insulting someone is not the best way to illicit their help. ------------------------------------------------------------------------ [2003-04-26 15:35:04] spagmoid at yahoo dot com If you declare a variable global twice, it gives you garbage the second time. IE: global $Bob; global $Bob; This was already reported, and sniper shot it down. That's what he does apparently, shoots down valid bugs in the goal of keeping PHP as buggy as possible! Maybe he works for Micro$oft? ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=23365&edit=1
