Duplicated code is one of the most pungent code smells. If you need to duplicate
the same code in three or more different places, we strongly encourage you to
look into extracting the code into a single class or operation.

It seems like the method you are trying to call exists only in some of the
possible types.


Let’s take a look at an example:


class A
{
    public function foo() { }
}

class B extends A
{
    public function bar() { }
}

/**
 * @param A|B $x
 */
function someFunction($x)
{
    $x->foo(); // This call is fine as the method exists in A and B.
    $x->bar(); // This method only exists in B and might cause an error.
}







Available Fixes


  1. Add an additional type-check:
    

    /**
 * @param A|B $x
 */
function someFunction($x)
{
    $x->foo();

    if ($x instanceof B) {
        $x->bar();
    }
}

    

    

    2. 

  2. Only allow a single type to be passed if the variable comes from a parameter:
    

    function someFunction(B $x) { /** ... */ }
