I know how to get the html source code via cUrl, but I want to remove the comments on the html document (I mean what is between ). In addition,

Answer 1

Try PHP DOM*:

$html = '
some content
'; // put your cURL result here

$dom = new DOMDocument;
$dom->loadHtml($html);

$xpath = new DOMXPath($dom);
foreach ($xpath->query('//comment()') as $comment) {
    $comment->parentNode->removeChild($comment);
}

$body = $xpath->query('//body')->item(0);
$newHtml = $body instanceof DOMNode ? $dom->saveXml($body) : 'something failed';

var_dump($newHtml);

Output:

string(36) "
some content
"
