You can use either Iframe or file_get_contents ();
Iframe:
<iframe src="http://google.com" style="width: 100%; height: 100%;">
file_get_contents ():
<?php echo file_get_contents('http://google.com'); ?>
With file_get_contents (), you should beware of a website that you extract from using relative URLs, which will break CSS, images, Javascript, etc.
