This code removes one p-tag:

function parse($html) {
    $dom = new DOMDocument();
    @$dom->loadHTML($html);
    $ps = $dom->getElementsByTagName('p');
    //die('
'.print_r($ps,1).'
');
    if ($ps->length === 1){
        $p = $ps->item(0);
        return $p->nodeValue;
    } else {
        return '';
    }
}
