#34468 [Csd]: Fatal error for current

ID: 34468 Updated by: sniper@php.net Reported By: j dot gizmo at aon dot at Status: Closed Bug Type: Feature/Change Request Operating System: Windows 2000 Server PHP Version: 5.0.5 Assigned To: zeev New Comment: current() is fixed in CVS. Previous Comments: ------------------------------------------------------------------------ [2005-09-12 11:17:52] j dot gizmo at aon dot at Okay, this bug isn't critical, but why is it a bogus? Is current() supposed to work on variables only? In all previous versions of PHP it worked on all arrays, wheter returned from a function or stored in a variable or whatever. So WHY the new behaviour starting with 5.0.5? ------------------------------------------------------------------------ [2005-09-11 23:43:45] 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 Feel free to fix the whole engine though with a patch... ------------------------------------------------------------------------ [2005-09-11 23:35:16] j dot gizmo at aon dot at Description: ------------ current() only works on variables; no longer on arrays returned from functions. This also explains Bug #34424, which has been classified as Bogus. Reproduce code: --------------- $x = current(explode(' ','a b')); echo $x; Expected result: ---------------- a Actual result: -------------- Fatal error: Only variables can be passed by reference in ... -------------- However, the following DOES work as expected: $a = current($x=&explode(" ","a b")); This new behaviour breaks backward compatibility. Furthermore, it introduces continuity problems. In both cases, an array is passed to current(), only one time it is stored in a variable and the other time it isn't. This should not make a difference, because even a "temporary array" should have a current element. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=34468&edit=1
