Summary: is_callable() and unnecessary backslash
Status: Open
Type: Bug
Package: Class/Object related
Operating System: *
PHP Version: 5.3.0
New Comment:
This bug is still present in 5.3.2 and also affects instantiating a new
class
from a string variable:
function __autoload($class)
{
echo "$class\n";
}
$obj = new MyProject\Thing();
// correct: MyProject\Thing
$obj = new \MyProject\Thing();
// correct: MyProject\Thing
$class = '\\MyProject\\Thing';
$obj = new $class();
// wrong: \MyProject\Thing

hi david, you are not in a namespace it is just a classname.

The two same class invokes autoloader with different class name (maybe
better term is non-canonicalized class name).
This means: every autoloader must call $name = ltrim($name, "\").
defined() removes leading "\" automatically, is_callable and
method_exists do not.

exists.

Description:
------------
is_callable() and method_exists() may invoke autoloader with
unnecessary namespace backslash.
\My\MyClass::func() is the same as My\MyClass::func().
Reproduce code:
---------------
function __autoload($name)
{
echo $name;
}
is_callable('\My\MyClass::func'); // ERROR
is_callable('My\MyClass::func'); // OK
method_exists('\My\MyClass', 'func'); // ERROR
method_exists('My\MyClass', 'func'); // OK
// defined works well:
defined('\My\MyClass::CONST'); // OK
defined('My\MyClass::CONST'); // OK
Expected result:
----------------
My\MyClass
My\MyClass
My\MyClass
My\MyClass
My\MyClass
My\MyClass
Actual result:
--------------
\My\MyClass
My\MyClass
\My\MyClass
My\MyClass
My\MyClass
My\MyClass
