    $dom = new DOMDocument('1.0');
    $dom->xmlStandalone = false;
    $manfiestNode = $dom->createElement('manifest',"");

    $manfiestNodeAttr->value = 'course_'.date_format($date,'U');
    $manfiestNode->appendChild($manfiestNodeAttr);
$manfiestNode->appendChild($dom->createAttribute('xmlns:xsi'))->appendChild($dom->createTextNode("http://www.w3.org/2001/XMLSchema-instance"));
    $metaData = $dom->createElement('metadata','');
    $manfiestNode->appendChild($metaData);

You have made a spelling mistake, instead of appendChild you write appendChid.

你拼错了，而不是appendChild你写了appendChid。

First correct it, and then check what happens.

首先纠正它，然后检查发生了什么。
