PHP Bug Type: Scripting Engine problem
Bug description: switch expressions seem to get cast to specific type.
Description:
------------
Switched expressions seem to be cast to a type before case matching
occurs.
If all case expressions are of the same type, either numeric, or string,
this problem does not arise.
It is not clear why, or really what type the switched expression is cast
to before comparision.
Reproduce code:
---------------
$t = array(0,1,2,3,'*','+','a', 'b')
foreach($t as $v)
switch ($v)
{
case 0: echo('0'); break;
case 1: echo('1'); break;
case 2: echo('2'); break;
case 3: echo('3'); break;
case '*': echo('*'); break;
default: echo($v); break;
}
Expected result:
----------------
0123*+ab
The first 5 array elements are output their respective case statements,
and the latter 3 are handled by the default case.
Actual result:
--------------
01230000
The first 5 array elements are output their respective case statements,
and the latter 3 are handled the 0 case.
