Description:
------------
parse_ini_file() correctly uses the | and & bitwise operators on constants. However, it does not correctly interpret the ^ (XOR) operator. Instead, it interprets the entire statement as a string.

Reproduce code:
---------------
*** test.ini ***

or = E_ERROR | E_PARSE
xor = E_ALL ^ E_NOTICE

*** PHP ***

$ini = parse_ini_file('test.ini');

echo $ini['or'] . ' ' . (E_ERROR | E_PARSE);
echo "\n";
echo $ini['xor'] . ' ' . (E_ALL ^ E_NOTICE);

Expected result:
----------------
5 5
6135 6135

Actual result:
--------------
5 5
E_ALL ^ E_NOTICE 6135

The php.ini says:

; Expressions in the INI file are limited to bitwise operators and parentheses:
; |        bitwise OR
; &        bitwise AND
; ~        bitwise NOT
; !        boolean NOT

This is valid also to files parsed by parse_ini_file() function.

I see. But shouldn't it include all of PHP's bitwise operators (http://us.php.net/language.operators.bitwise)? The fact that it only parses a subset is confusing and should probably be documented on parse_ini_file()'s documentation page.

Or, perhaps the php.ini comment could be changed from:

"Expressions in the INI file are limited to bitwise operators"

(implying all bitwise operators) to

"Expressions in the INI file are limited to the following bitwise operators"

That seems a bit clearer to me. Thanks for your quick response.
