Operating system: Linux Fedora 13
PHP version: 5.3.3
Package: Scripting Engine problem
Bug Type: Bug
Bug description:Or operator inconsistency
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
