ID: 34358 Updated by: derick@php.net Reported By: pacha dot shevaev at gmail dot com -Status: Open +Status: Bogus Bug Type: Scripting Engine problem Operating System: * PHP Version: 5.* New Comment: It's still bogus, you can call it a BC break if you want, but we're not going to change this back. Previous Comments: ------------------------------------------------------------------------ [2005-09-15 15:23:37] pacha dot shevaev at gmail dot com I'm not an expert in PHP internals but there's a guy(stereofrog) on the SitePoint forum who has a different point of view(http://www.sitepoint.com/forums/showpost.php?p=2146304&postcount=9): [quote] it's 'simply ridiculous. They have a code in zend_compile.c that handles "$this=$x" and copy-pasted that code in the function that comples assignment by reference. This should prevent "$this=&$x" (which is wrong), but for some reason it "prevents" "$x=&$this" as well (which is absolutely correct). It's pure c-level bug and has nothing to do with "new object model" and other blah-blah.

It might have worked in PHP 4 but it does not and will not work in PHP 5. ------------------------------------------------------------------------ [2005-09-15 13:37:28] pacha dot shevaev at gmail dot com I still find it a bug. I need a reference to $this for BC with PHP4 in the following piece of code: function &getRootDataSource() { $root =& $this; while ($root->parent != NULL) { $root =& $root->parent; } return $root; } ------------------------------------------------------------------------ [2005-09-03 13:44:07] derick@php.net Thank you for taking the time to write to us, but this is not a bug.
