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

There's no or-operator in a case statement.
Your expression actually evaluates to TRUE.

Description:
------------
When using a variable og type String, the switch structure behaives
odd.

Reproduce code:
---------------
<?php
$modes = array("byId", "byName", "asSelect", "", null, "as", "Id",
"Name", "Select");

print "<pre>";
print_r($modes);
print "</pre>";

foreach($modes as $mode) {
        print $mode;
        switch($mode) {
                case "case1":
                        print "<div>case1 => uses ".$mode."</div>";
                        break;
                case "case2" || "case3":
                        print "<div>case2 or case3 => uses ".$mode."</div>";
                        break;
                default:
                        print "<div>default => cannot use ".$mode."</div>";
        }
}
?>

Expected result:
----------------
Array
(
    [0] => byId
    [1] => byName
    [2] => asSelect
    [3] => 
    [4] => 
    [5] => as
    [6] => Id
    [7] => Name
    [8] => Select
)

byId
default => cannot use
byName
default => cannot use
asSelect
default => cannot use
("" and null)
default => cannot use
default => cannot use
as
default => cannot use
Id
default => cannot use
Name
default => cannot use
Select
default => cannot use

Actual result:
--------------
Array
(
    [0] => byId
    [1] => byName
    [2] => asSelect
    [3] => 
    [4] => 
    [5] => as
    [6] => Id
    [7] => Name
    [8] => Select
)

byId
case2 or case3 => uses byId
byName
case2 or case3 => uses byName
asSelect
case2 or case3 => uses asSelect
default => cannot use
default => cannot use
as
case2 or case3 => uses as
Id
case2 or case3 => uses Id
Name
case2 or case3 => uses Name
Select
case2 or case3 => uses Select
