DOMDocument::loadHTML

(PHP 5, PHP 7, PHP 8)

DOMDocument::loadHTML — Load HTML from a string

說明

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.

參數

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

成功時返回 true， 或者在失敗時返回 false。 If called statically, returns a DOMDocument 或者在失敗時返回 false.

錯誤／異常

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.

在 PHP 8.0.0 之前可以靜態(tài)調用此方法，但會發(fā)出 E_DEPRECATED 錯誤。自 PHP 8.0.0 起，靜態(tài)調用此方法會拋出 Error 異常

盡管非正確格式化的 HTML 仍應該被成功調入，但此函數會在遇到錯誤標記時產生 E_WARNING 錯誤。libxml 錯誤處理函數可以用來處理這類錯誤。

范例

示例 #1 Creating a Document

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