How to use interface in class methode

I am struggling to understand what arguments to use for a particular methode from a class in PHP.

$client = new Client();
$client->execute();

The execute() methode requires an argument. Looking at the execute() methode in the Client class it seems linked (linked is probably not the right word here) to the RequestInterface interface. Which contains two methodes: getMethod() and getPath(). How do I use the execute() methode?

    class Client
    { 
            public function execute(RequestInterface $request)
            {
                 //do stuff
            }
    }

interface RequestInterface
{
    /**
     * @return string
     */
    public function getMethod();

    /**
     * @return string
     */
    public function getPath();
}

Further to my comment, that would look something like this. Class MyRequest implements interface RequestInterface. You can then inject method Client::execute() with a RequestInterface type object ($request).

<?php
Class MyRequest implements RequestInterface
{
    public function getMethod()
    {
        // TODO: Implement getMethod() method.
    }

    public function getPath()
    {
        // TODO: Implement getPath() method.
    }
}

class Client
{
    public function execute(RequestInterface $request)
    {
        return 0;
    }
}

interface RequestInterface
{
    /**
     * @return string
     */
    public function getMethod();

    /**
     * @return string
     */
    public function getPath();
}

$request = new MyRequest();
$client = (new Client)->execute($request);

var_dump($client); //0

see it in action
