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(shù)

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(shí)返回 true， 或者在失敗時(shí)返回 false。 If called statically, returns a DOMDocument 或者在失敗時(shí)返回 false.

錯(cuò)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(diào)用此方法，但會(huì)發(fā)出 E_DEPRECATED 錯(cuò)誤。自 PHP 8.0.0 起，靜態(tài)調(diào)用此方法會(huì)拋出 Error 異常

盡管非正確格式化的 HTML 仍應(yīng)該被成功調(diào)入，但此函數(shù)會(huì)在遇到錯(cuò)誤標(biāo)記時(shí)產(chǎn)生 E_WARNING 錯(cuò)誤。libxml 錯(cuò)誤處理函數(shù)可以用來處理這類錯(cuò)誤。
