Bug #7515 [Com]: very weird, magic, invisible referencing

Edit report at https://bugs.php.net/bug.php?id=7515&edit=1 ID: 7515 Comment by: yann-gael at gueheneuc dot net Reported by: waldschrott@php.net Summary: very weird, magic, invisible referencing Status: Closed Type: Bug Package: Scripting Engine problem Operating System: linux + win2k PHP Version: 4.0 Latest CVS (28/10/2000) Block user comment: N Private report: N New Comment: PS. I narrowed down the test: class obj { function method() { } } $o->root=new obj(); var_dump($o); $o->root->method(); var_dump($o); and its output with PHP 4.2.3 compiled for m68k-amigaos: object(stdClass)(1) { ["root"]=> object(obj)(0) { } } object(stdClass)(1) { ["root"]=> &object(obj)(0) { } } (note the ampersand in the second dump), while, with PHP 5.2.14 for Windows, the output is: object(stdClass)#2 (1) { ["root"]=> object(obj)#1 (0) { } } object(stdClass)#2 (1) { ["root"]=> object(obj)#1 (0) { } } Does it make sense that in the second assign "$o->root->method();", the method is viewed as a reference to and object? Please forgive me if my question is silly, I am a newbie in OO PHP. Previous Comments: ------------------------------------------------------------------------ [2011-11-22 22:44:58] yann-gael at gueheneuc dot net I compiled PHP 4.2.3 for m68k-amigaos and the test case tests/lang/029.php fails. Could you tell me more about what has been changed into the Zend engine to fix this bug so that I can track this change and the bug? (I don't think that I should reopen this bug for m68k-amigaos, should I?) Thanks!

It creates that member as a refrence. /* i set this to critical because i think this should be resloved right away */ - Brad ------------------------------------------------------------------------ [2002-01-11 16:11:31] bryce at redhat dot com I'm looking at putting php 4.1.1 into the next RH release however I noticed that this bug still seems to be happening (From make test) Running tests in /usr/src/redhat/php-4.1.1//tests/lang ... OO Bug Test (Bug #7515) (029.phpt) ... failed [root@dhcpd201 lang]# cat 029.exp success [root@dhcpd201 lang]# cat 029.out failure I this something that can either be fixed or can I turn a blind eye to this..

If this report is outstanding, PHP Version is better to be updated... ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
