PHP中的Redeclare类

Question

Anyone know how to redeclare function?
For example:

class Name{}
//Code here
class Name{}

And the output is: Cannot redeclare class
So I tried to name the class as a variable:

$foo = 'name';
class $foo{}

//Code

class $foo{}

Edit: I have a DataBase table and I am reading data from the table user 'while()' loop.
I have a class that uses the table and echo some information. That is the reason.

And it's still not working...
Any suggestions?

Use PHP NameSpace

namespace A {

    class Name {

        function __toString() {
            return __METHOD__;
        }
    }
}

namespace B {

    class Name {
        function __toString() {
            return __METHOD__;
        }
    }
}

namespace C {

    echo new \A\Name ,PHP_EOL;
    echo new \B\Name ,PHP_EOL;
}

Output

A\Name::__toString
B\Name::__toString
