Bug description: casting of string with numbers in it still does INT conversion
Description:
------------
In a switch, a value that is declared as string with a prefix 0 will
automatically disappear in switched values, even if all of them are
specifically casted as a string.
Reproduce code:
---------------
$field = (string)"0123";
settype($field, 'string'); // just to make sure, for testcase
switch ($field)
{
case '123': $result = 'first'; break;
case '456': $result = 'second'; break;
default: $result = 'third'; break;
}
echo $result; // first, due to string / int conversion.
switch ((string)$field) // explicit cast to string
{
case (string)'123': $result = 'first'; break; // more (unneccesary
casts just to be sure)
case (string)'456': $result = 'second'; break;
default: $result = 'third'; break;
}
echo $result; // first! ????
Expected result:
----------------
I would have expected the last result echo to be third because of the
explicit typecasting.
This problem appears in all php versions up to 5.2 snapshot of today.
Actual result:
--------------
the code in the example speaks for itself.
