#49019 [Opn->Fbk]: order of operations is not valid for assignment in all cases

ID: 49019 Updated by: jani@php.net Reported By: michaeldnelson dot mdn at gmail dot com -Status: Open +Status: Feedback Bug Type: Scripting Engine problem Operating System: freebsd PHP Version: 5.2.10 New Comment: = is associated on right, || is associated on left, so that's exactly what your code does.. Previous Comments: ------------------------------------------------------------------------ [2009-07-22 17:10:36] michaeldnelson dot mdn at gmail dot com Description: ------------ It appears = has a higher precedence than || in some situations which is contrary to the manual. This exception is not noted as far as I can tell. var_dump(!$test = false || !$test2 = false); is being interpreted like this var_dump(!$test = (false || !$test2 = false)); instead of like this var_dump((!$test = false) || (!$test2 = false)); If I missed something my apologies. Thanks, Michael D. Nelson Reproduce code: --------------- --- From manual page: language.operators.precedence --- var_dump(!$test = false || !$test2 = false); echo "TEST\n"; var_dump($test); echo "TEST2\n"; var_dump($test2); Expected result: ---------------- bool(true) TEST bool(false) TEST2 NULL Actual result: -------------- bool(false) TEST bool(true) TEST2 bool(false) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=49019&edit=1
