<?php $url = 'https://www.youtube.com/watch?v=u9-kU7gfuFA'; preg_match('/[\\?\\&]v=([^\\?\\&]+)/', $url, $matches); $id = $matches[1]; $width = '800px'; $height = '450px'; ?> <iframe id="ytplayer" type="text/html" width="<?php echo $width ?>" height="<?php echo $height ?>" src="https://www.youtube.com/embed/<?php echo $id ?>?rel=0&showinfo=0&color=white&iv_load_policy=3" frameborder="0" allowfullscreen></iframe>
