Description:
------------
---
From manual page: http://php.net/manual/en/language.operators.logical.php
---
$a and $b	And	TRUE if both $a and $b are TRUE.
$a or $b	Or	TRUE if either $a or $b is TRUE.
The 'and' and the 'or' is use for bits,but this doc use for Logical.

Test script:
---------------
<?php
$a = 4;
$b = 1;
$res1 = $a and $b;
$res2 = $a & $b;
$res3 = $a or $b;
$res4 = $a | $b;
var_dump($res1);//the res1 is 4,but the manual describes the result to be a bool type.
var_dump($res2);
var_dump($res3);
var_dump($res4);

Expected result:
----------------
$a & $b	And	Bits that are set in both $a and $b are set.
$a | $b	Or (inclusive or)	Bits that are set in either $a or $b are set.

Actual result:
--------------
$a and $b	And	TRUE if both $a and $b are TRUE.
$a or $b	Or	TRUE if either $a or $b is TRUE.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

http://php.net/manual/en/language.operators.precedence.php
= has higher precedence than and/or.
