DOMDocument::loadHTML

(PHP 5, PHP 7, PHP 8)

DOMDocument::loadHTML — Load HTML from a string

说明

public DOMDocument::loadHTML(string $source, int $options = 0): DOMDocument|bool

The function parses the HTML contained in the string source. Unlike loading XML, HTML does not have to be well-formed to load. This function may also be called statically to load and create a DOMDocument object. The static invocation may be used when no DOMDocument properties need to be set prior to loading.

参数

source

The HTML string.

options

Since Libxml 2.6.0, you may also use the options parameter to specify additional Libxml parameters.

返回值

成功时返回 true， 或者在失败时返回 false。 If called statically, returns a DOMDocument 或者在失败时返回 false.

错误／异常

If an empty string is passed as the source, a warning will be generated. This warning is not generated by libxml and cannot be handled using libxml's error handling functions.

此方法可以被静态调用,但会抛出一个 E_STRICT 错误。

尽管非正确格式化的 HTML 仍应该被成功调入，但此函数会在遇到错误标记时产生 E_WARNING 错误。libxml 错误处理函数可以用来处理这类错误。

范例

示例 #1 Creating a Document

<?php
$doc = new DOMDocument();
$doc->loadHTML("<html><body>Test<br></body></html>");
echo $doc->saveHTML();
?>
