DOMDocument::loadHTMLFile

(PHP 5, PHP 7, PHP 8)

DOMDocument::loadHTMLFile — Load HTML from a file

说明

public DOMDocument::loadHTMLFile(string $filename, int $options = 0): DOMDocument|bool

The function parses the HTML document in the file named filename. Unlike loading XML, HTML does not have to be well-formed to load.

参数

filename

The path to the HTML file.

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 filename or an empty file is named, a warning will be generated. This warning is not generated by libxml and cannot be handled using libxml's error handling functions.

在 PHP 8.0.0 之前可以静态调用此方法，但会发出 E_DEPRECATED 错误。自 PHP 8.0.0 起，静态调用此方法会抛出 Error 异常

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->loadHTMLFile("filename.html");
echo $doc->saveHTML();
?>
