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

'and' is equivalent to &, which is a bitwise operator. && is something
else entirely.

Description:
------------
Result of 'and' operator not what is expected. 1 and 0 and 1 => 1?
Should be 0. See attached code sample. '&&' operator does function
correctly however.

Reproduce code:
---------------
$primary_err_valid = (($_POST['primary_err'] != "category") and
($_POST['primary_err'] != "separator"));
$secondary_err_valid = (($_POST['secondary_err'] != "category") and
($_POST['secondary_err'] != "separator"));
$tertiary_err_valid = (($_POST['tertiary_err'] != "category") and
($_POST['tertiary_err'] != "separator"));
$error_valid = ($primary_err_valid) and ($secondary_err_valid) and
($tertiary_err_valid);

echo "Pri: $primary_err_valid <br>";
echo "Sec: $secondary_err_valid <br>";
echo "Tri: $tertiary_err_valid <br>";
echo "Total Error: $error_valid <br>";


Expected result:
----------------
Pri: 1
Sec:
Tri: 1
Total Error:

Actual result:
--------------
Pri: 1
Sec:
Tri: 1
Total Error: 1
