From:
Operating system: CentOS release 5.4 (Final)
PHP version: 5.3.8
Package: Scripting Engine problem
Bug Type: Bug
Bug description:print() results in bad logic
Description:
------------
Unlike echo, the print construct is allowed inside logic clauses. If it is
reached (not short-circuited), it will cause the rest of that clause to be
true.
Tested with 5.3.8 and PHP 5.3.9RC5-dev, both with default configure.
Test script:
---------------
<?php
echo (false && print('')) ? "Fail\n" : "Pass\n";
echo (print('') && false) ? "Fail\n" : "Pass\n";
echo (print('') && false && false) ? "Fail\n" : "Pass\n";
echo ((print('') && false) && true) ? "Fail\n" : "Pass\n";
echo ((print('') && false) && false) ? "Fail\n" : "Pass\n";
?>
Expected result:
----------------
The word "Pass" five times.
Actual result:
--------------
The middle three fail. The first and last pass, and are included to
demonstrate
the limits of the bug.
