Description:
------------
The bug takes place in versions of php from 4 to 5. Because of some reasons number 0 is equated with any string. The equal operator (==) is used. The problem is well illustrated with the "Reproduce code".

Reproduce code:
---------------
$i = 0;
$b = $i == "str";
var_dump($b);

Expected result:
----------------
bool(false)

Actual result:
--------------
bool(true)

Oh, sorry. I did look through the documentation, but didn't find the needed page. For those, who have the same problem, the needed page is http://www.php.net/manual/en/types.comparisons.php .

Thank you.
