Function to extract the contents from a specific div id from any webpage

The below function extracts the contents from the specified div and returns it. If no divs with the ID are found, it returns false.

function getHTMLByID($id, $html) {
    $dom = new DOMDocument;
    libxml_use_internal_errors(true);
    $dom->loadHTML($html);
    $node = $dom->getElementById($id);
    if ($node) {
        return $dom->saveXML($node);
    }
    return FALSE;
}

$id is the ID of the <div> whose content you're trying to extract, $html is your HTML markup.

Usage example:

$html = file_get_contents('http://www.mysql.com/');
echo getHTMLByID('tagline', $html);

Output:

The world's most popular open source database

Try this:

$html = <<<HTML
<div class="basic">
    <div class="math">
        <div class="winner">
            <div class="under">
                <div class="checker">
                    <strong>check</strong>
                </div>
            </div>
        </div>
    </div>
</div>;
HTML;

$dom = new DOMDocument();

$dom->loadHTML($html);

$xpath = new DOMXPath($dom);

$div = $xpath->query('//div[@class="under"]');

$div = $div->item(0);

echo $dom->saveXML($div);

This will output:

<div class="under">
    <div class="checker">
        <strong>check</strong>
    </div>
</div>

I'm not sure what you asking but this might be it

preg_match_all("<div class='under'>(.*?)</div>", $htmlsource, $output);

$output should now contain the inner content of that div
