php 中的 DOMDocument 中的编码问题

Question

When you do this:当你这样做时：

$d = new DOMDocument();
$e = new DOMElement('myelement', 'hi &nbsp; bye');
$d->appendChild($e);
$d->loadXML($d->saveXML());

..you get the following error: ..您收到以下错误：

PHP Warning:  DOMDocument::loadXML(): Entity 'nbsp' not defined in Entity, line: 2 in php shell code on line 1

Why does this happen?为什么会这样？ Shoudn't libxml handle entities correctly? libxml不应该正确处理实体吗？

Answer 1

Use loadHTML() instead since this entity is a HTML entity and not a generic XML entity.请改用loadHTML() ，因为此实体是 HTML 实体，而不是通用 XML 实体。
