How to use a static and an instance method with the same name on the same class?

Question

I am trying to recreate Laravel ORM (Eloquent).

In Laravel we can do something like:

Model::where("condition1")->where("condition2")->get();

So far my attempts to recreate this lead me to write this code:

class DB {

    static $condition ;

    public static function chidlClassName() {
        return get_called_class();
    }

    static function where( $cond ) {  

        self::$condition[] = $cond;
        return new DB();
    }

    public function where( $cond ){

        self::$condition[] = $cond ;
        return $this; 
    }


    function get(){

        $cond = implode(' AND ' ,self::$condition);
    }
}

class Modle extends DB {}

But it wont work because both where functions have the same name...

How does the Laravel do it?

I haven't seen how Eloquent does it, but way to achieve this would be not to declare the method you want to reuse in neither the base class, nor the extended class; and instead use the magic methods __call($method, $arguments) and __callStatic($method, $arguments).

A simple example would be this:

class Base {

    public static function __callStatic($method, $arguments) {
        if ('foo' === $method) {
            echo "static fooing\n";
        }
        return new static();
    }

    public function __call($method, $arguments) {
        if ('foo' === $method) {
            echo "instance fooing\n";
        }
    }

}

class Child extends Base {

}

Which would be used as:

Child::foo()->foo();

The first foo() goes through __callStatic() in the Base class, because it's a static call. The second foo() goes through __call(), since it's a non-static call.

This would output:

static fooing
instance fooing

You can see it working here.
