ID: 52694 User updated by: biolizard dot mail at gmail dot com Reported by: biolizard dot mail at gmail dot com Summary: Or operator inconsistency Status: Bogus Type: Bug Package: Scripting Engine problem Operating System: Linux Fedora 13 PHP Version: 5.3.3 Block user comment: N New Comment: I apologize for the inconvenience. Previous Comments: ------------------------------------------------------------------------ [2010-08-25 09:14:21] ras...@php.net It follows the operator precedence rules documented here: http://php.net/manual/en/language.operators.precedence.php OR and || are obviously not synonymous. Your examples match the documented precedence table. ------------------------------------------------------------------------ [2010-08-25 09:11:13] biolizard dot mail at gmail dot com Description: ------------ The logical operator 'or' and the operator '||' produce different values, which is inconsistent with the description and the examples presented in the PHP website. However, when returning from a function, the inconsistency is even more problematic. The operator 'or', when used in a statement (e.g., assignment), returns the first value that is not false. However, when used as a return expression the returned value is either true or false. Test script: --------------- <?php function f() { return 'ola' || 'adeus'; } function p() { return 'ola' or 'adeus'; } $a = 'ola' || 'adeus'; $b = 'ola' or 'adeus'; echo $a . "\n"; echo $b . "\n"; echo f() . "\n"; echo p() . "\n"; ?> Expected result: ---------------- 1 ola 1 ola Actual result: -------------- 1 ola 1 1 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=52694&edit=1
