        ."<h1 id='h2'>hhhh222</h1>"
        ."<h1 id='h3'>hhhh333</h1>";

    You can also do like this:

    $html = "<h1 id='h1' >hhhh111</h1>
    <h1 id='h2' >hhhh222</h1>
    <h1 id='h3' >hhhh333</h1>";
    $dom = new DomDocument();
    $dom->loadHtml($html);
    $xpath = new DomXpath($dom);
    $div = $xpath->query("//*[@id='h2']")->item(0)->nodeValue;
          echo $div;
