如何在php中嵌入YouTube频道网址？

I am trying to embed YouTube channel URL in my php page. But it gives following error:

Refused to display 'https://www.youtube.com/channel/fakecode' in a frame because it set 'X-Frame-Options' to 'SAMEORIGIN'.

<div id="bgvideo" >
                <div class="container" >
                    <div class="row" >
                        <div class="col-sm-8 col-sm-offset-2">
                            <div class="responsive-video">
                                <iframe width="420" height="315" src="https://www.youtube.com/channel/fakecode" frameborder="0" allowfullscreen></iframe>

                            </div>
                        </div>
                    </div>
                </div>
            </div>

Try this one

<iframe width="420" height="315" src="https://www.youtube.com/embed/A6XUVjK9W4o" frameborder="0" allowfullscreen></iframe>
