ID: 15025 Updated by: derick@php.net Reported By: jimmy@harlindong.com -Status: Verified +Status: Critical Bug Type: Scripting Engine problem Operating System: FreeBSD, Linux PHP Version: 4.3.0-dev Previous Comments: ------------------------------------------------------------------------ [2002-09-17 20:50:58] iliaa@php.net updating version. ------------------------------------------------------------------------ [2002-09-17 13:31:26] kylam@superapple.org Verified with 4.2.3 on Windows 2000 too. ------------------------------------------------------------------------ [2002-01-13 22:32:27] jimmy@harlindong.com $c should not have been affected by the assignment to $b because $c should only be a copy to $a. What happened is the first echo shows 5 and after assignment to $b, the content of $c changes to 1 when it should stay as 5. ------------------------------------------------------------------------ [2002-01-13 22:18:55] jimmy@harlindong.com You can guess / see from this simple script: $a = array(5); $b =& $a[0]; $c = $a; echo $c[0]; $b = 1; echo $c[0]; ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=15025&edit=1
