#44933 [Bgs]: Assignment is done as if by reference

ID: 44933 User updated by: remon at menpmedia dot nl Reported By: remon at menpmedia dot nl Status: Bogus Bug Type: Class/Object related Operating System: Fedora Core 4 PHP Version: 5.2.6 New Comment: Tested versions: php 5.2.4 / fedora core 8 / x64: no problem php 5.2.6 / fedora core 4 / x32: bug occurs php 5.0.5 / fedora core 4 / x32: bug occurs php 5.2.4 / win32 : bug occurs (downloaded the binary and executed script) php 5.2.6 / win32 : bug occurs php 4.4.8 / win32 : no problem --- Thoughts: Has this behaviour changed in php5? why does ' = ' do the same as ' =& ' ? Why do 2 different FC4 servers have this problem and an FC8 does not? Could this be a difference in 32 bit and 64 bit versions? Previous Comments: ------------------------------------------------------------------------ [2008-05-07 08:53:17] derick@php.net Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php Both PHP versions give the same *correct* result that you get under \"Actual result\". ------------------------------------------------------------------------ [2008-05-07 08:40:41] remon at menpmedia dot nl Description: ------------ Problem: Changing property of a copy of an object results in the changing of the original object as if by reference. Correct output is from 5.2.4 Incorrect output is from 5.2.6 This problem does NOT occur when using an array! configure command (taken from phpinfo()) './configure' '--with-apxs' '--with-curl=/usr/local/lib' '--with-gd' '--enable-gd-native-ttf' '--with-ttf' '--with-gettext' '--with-jpeg-dir=/usr/local/lib' '--with-freetype-dir=/usr/local/lib' '--with-kerberos' '--with-openssl' '--with-mcrypt' '--with-mhash' '--with-mysql=/usr' '--with-mysqli=/usr/bin/mysql_config' '--with-pear' '--with-png-dir=/usr/local/lib' '--with-zlib' '--with-zlib-dir=/usr/local/lib' '--enable-zip' '--with-iconv=/usr/local' '--enable-bcmath' '--enable-calendar' '--enable-ftp' '--enable-magic-quotes' '--enable-sockets' '--enable-mbstring' other info; sorry, unavailable; we do not have root access to the server in question. Cannot get a diff between the ini and ini-dist, cannot do a trace. Reproduce code: --------------- <?php $one = new stdClass(); $one->variable = "hello"; $two = $one; $two->variable = "goodbye"; var_dump($one); ?> Expected result: ---------------- object(stdClass)#3 (1) { ["variable"]=> string(5) "hello" } Actual result: -------------- object(stdClass)#1 (1) { ["variable"]=> string(7) "goodbye" } ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=44933&edit=1
