#44179 [Opn->Bgs]: Ternary Operator Does Not Accept Text Logical Operators

ID: 44179 Updated by: rasmus@php.net Reported By: rpanning at hotmail dot com -Status: Open +Status: Bogus Bug Type: Unknown/Other Function Operating System: XP Pro SP2 PHP Version: 5.3CVS-2008-02-20 (snap) New Comment: Please check the operator precedence documentation. The whole point of 'and', 'or' and 'xor' is that they are right at the bottom of the precedence table. Only the ',' operator is below them. See: http://php.net/manual/en/language.operators.php Previous Comments: ------------------------------------------------------------------------ [2008-02-20 04:30:35] rpanning at hotmail dot com Description: ------------ It seems that the ternary conditional operator does not accept the text logical operators (and, or, xor). They assign int 1 instead of the other expressions. The xor is even odder in that if the TRUE comes before the xor, it will not assign anything. If it is the reverse, it will assign int 1. Tested this with both PHP 5.2.5 and the latest snap of 5.3. Don't believe this is the expected behavior. Reproduce code: --------------- $and = (TRUE and TRUE ? 'True' : 'False'); $or = (FALSE or TRUE ? 'True' : 'False'); $xor = (TRUE xor FALSE ? 'True' : 'False'); $aa = (TRUE && TRUE ? 'True' : 'False'); $ll = (TRUE || FALSE ? 'True' : 'False'); print('and = ' . $and . "<br>\r\n"); print('or = ' . $or . "<br>\r\n"); print('xor = ' . $xor . "<br>\r\n"); print('&& = ' . $aa . "<br>\r\n"); print('|| = ' . $ll . "<br>\r\n"); Expected result: ---------------- and = True<br> or = True<br> xor = True<br> && = True<br> || = True<br> Actual result: -------------- and = 1<br> or = 1<br> xor = <br> && = True<br> || = True<br> ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=44179&edit=1
