ID: 44658 User updated by: mo at nevali dot net Reported By: mo at nevali dot net Status: Bogus Bug Type: Arrays related Operating System: FreeBSD 6 PHP Version: 5.2.5 New Comment:
If this bug has been marked as bogus, does it mean it's going to get summarily ignored from here on in? It would be nice if somebody could actually try _running_ the test-case instead of dismissing it out of hand; aspects of the behaviour are clearly incorrect (notably the inconsistency), even if it's the case that my summary of it is wrong. Previous Comments: ------------------------------------------------------------------------ [2008-04-07 12:37:27] mo at nevali dot net My apologies, in my previous follow-up, I meant to write $foo->stuff where I wrote $foo->thing2. In my testcase, there's no such property as $foo->thing2! ------------------------------------------------------------------------ [2008-04-07 12:36:07] mo at nevali dot net So, how do you explain the difference in behaviour when the (should- be-inert) line in Foo::__construct() is removed? Also, while I'm perfectly well aware that references are not pointers, even calling (for example): $this->thing = array_merge($foo->thing, array()); in Bar::__construct() causes $bar->thing to become a reference. If this report _is_ bogus, then: a) Creating a deep reference (i.e., $this->thing2 =& $this- >thing['stuff']: in Foo::__construct()) should have no bearing on anything; $foo->thing2 is not used beyond that initial assignment. b) How is one supposed to duplicate the contents of an array given a reference to it? Last I heard, the use of clone was only supported for objects. Whilst this report may be, on the face of it, bogus, there is a bug here in either case. ------------------------------------------------------------------------ [2008-04-07 12:11:46] [EMAIL PROTECTED] This is the expected and correct output: Created foo, foo->thing['stuff'] = 1234 Creating Bar, foo->thing['stuff'] = 1234 Created bar, bar->thing2['stuff'] = ABC Created bar, foo->thing['stuff'] = ABC Hint: References are not pointers. ------------------------------------------------------------------------ [2008-04-07 11:46:21] mo at nevali dot net Description: ------------ Some circumstances involving deep references into arrays can cause assignment of those arrays to always assign references instead of values. Reproduce code: --------------- Please see http://nevali.net/docs/array-refs-testcase.phps Expected result: ---------------- The code should produce the following output: Created foo, foo->thing['stuff'] = 1234 Creating Bar, foo->thing['stuff'] = 1234 Created bar, bar->thing2['stuff'] = ABC Created bar, foo->thing['stuff'] = 1234 Actual result: -------------- Created foo, foo->thing['stuff'] = 1234 Creating Bar, foo->thing['stuff'] = 1234 Created bar, bar->thing2['stuff'] = ABC Created bar, foo->thing['stuff'] = ABC If the (marked) line in Foo's constructor: $this->stuff =& $this->thing['stuff']; is removed, the output is as expected, even though this code should be inert (Foo::stuff is not referenced from anywhere else in the test code). ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=44658&edit=1
