-Summary: Ternary Operator Does Not Accept Text Logical
Operators
Reported By: rpanning at hotmail dot com
Status: Bogus
Bug Type: Unknown/Other Function
Operating System: XP Pro SP2

New Comment:
Why does the operator precedence matter? They still don't work.
Shouldn't "and" function the same as "&&"? The only time operator
precedence would matter is if there were multiple operators in the
expression. In this example there is only one for each expression, so
operator precedence shouldn't come into play.

Please check the operator precedence documentation. The whole point of
'and', 'or' and 'xor' is that they are right at the bottom of the
precedence table. Only the ',' operator is below them.
See: http://php.net/manual/en/language.operators.php

Description:
------------
It seems that the ternary conditional operator does not accept the text
logical operators (and, or, xor). They assign int 1 instead of the other
expressions.
The xor is even odder in that if the TRUE comes before the xor, it will
not assign anything. If it is the reverse, it will assign int 1.
Tested this with both PHP 5.2.5 and the latest snap of 5.3. Don't
believe this is the expected behavior.
Reproduce code:
---------------
$and = (TRUE and TRUE ? 'True' : 'False');
$or = (FALSE or TRUE ? 'True' : 'False');
$xor = (TRUE xor FALSE ? 'True' : 'False');
$aa = (TRUE && TRUE ? 'True' : 'False');
$ll = (TRUE || FALSE ? 'True' : 'False');
print('and = ' . $and . "<br>\r\n");
print('or = ' . $or . "<br>\r\n");
print('xor = ' . $xor . "<br>\r\n");
print('&& = ' . $aa . "<br>\r\n");
print('|| = ' . $ll . "<br>\r\n");
Expected result:
----------------
and = True<br>
or = True<br>
xor = True<br>
&& = True<br>
|| = True<br>
Actual result:
--------------
and = 1<br>
or = 1<br>
xor = <br>
&& = True<br>
|| = True<br>
