Summary: strcasecmp does not warn user if both params are not
strings

New Comment:
PHP is a weakly typed language by design: if a scalar can be coerced into the
type that a function expects, it will be.
Expected behaviour â not a bug.

I believe that somewhere the underlying C source code is converting the PHP
TRUE,
i.e. 1 to "1"

Description:
------------
When I provide strcasecmp with two parameters where one is TRUE and the other
is a
string, php does not generate a warning to say that the first parameter needs
to
be a string and silently converts TRUE to "1" and executes.
Test script:
---------------
<?php
var_dump(strcasecmp(TRUE, "bob"));
// -49
Expected result:
----------------
I expected a parser error message.
Actual result:
--------------
-49
