Bug description:is_callable() returns false on callable functions when not
specifying namespace
Description:
------------
First sorry, I can only test this case with PHP 5.3.3 but I
didn't find any bugs referring to is_callable() since then, so I
think it's worth reporting.
The problem is that is_callable() will return false if you don't
specify the eventual namespace you're using.
Test script:
---------------
<?php
namespace Foo;
function bar() {
return 'bar!';
}
var_dump(is_callable('bar'));
var_dump(is_callable('\Foo\bar'));
var_dump(bar());
var_dump(\Foo\bar());
Expected result:
----------------
bool(false)
bool(true)
string(4) "bar!"
string(4) "bar!"
Actual result:
--------------
bool(true)
bool(true)
string(4) "bar!"
string(4) "bar!"
