'How do I use Fetch in React?

    React Code:

    const response = await fetch("../componentsunused/testingphp.php", {

      headers: {
        "Content-Type": "application/json" // request content type
      }
      
    });
    console.log("myResponse:" + JSON.stringify(response))

    this.setState({ items: await response.json() });

    PHP Code:

    $arr = array('a' => "123");

    echo json_encode($arr);

myResponse in console always comes out as an empty array. I checked and the request went through and was returned okay. What is wrong? Thank you very much for your help.
