您需要?jiǎng)?chuàng)建您之后的元素，然后用于insertBefore()在文檔中定位這個(gè)新節(jié)點(diǎn)（$node->firstChild首先用于定位它）......
$dom = new DOMDocument;
$dom->loadHTML($html);
$xpath = new DOMXpath($dom);
$ods22_tmp_t = $xpath->query("//*[contains(@class, 'PPToggle')]");
foreach($ods22_tmp_t as $node) {
$th = $dom->createElement("th", "Operator");
$node->insertBefore($th, $node->firstChild);
}
