Use CURL to read the remote URL to fetch the HTML.

$url = "http://www.example.com";
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);
$output = curl_exec($curl);
curl_close($curl);

Then use PHP's DOM object model to parse the HTML.

For example to fetch all <h1> tags from the source,

$DOM = new DOMDocument;
$DOM->loadHTML( $output);

//get all H1
$items = $DOM->getElementsByTagName('h1');

//display all H1 text
 for ($i = 0; $i < $items->length; $i++)
        echo $items->item($i)->nodeValue . "<br/>";
