php expects parameter 2 json_encode error-CodePudding

I have this array that returns a parameter error. Why?

        echo json_encode(
        array("replies" => array(
        array("message" => "Success ✅")
        )),
        array("variables" => array(
        array("data1" => "data2")
        ))          
        );

CodePudding user response：

You need to wrap the array in a single variable because json_encode second argument is the flag and you have passed the array so it's a return error. For more info see this link https://www.php.net/manual/en/function.json-encode.php or try with below example

echo json_encode(
    [["replies" => ["message" => "Success"]],
    ["variables" => ["data1" => "data2"]]]);
