DOMDocument::loadHTML
(PHP 5, PHP 7)
DOMDocument::loadHTML — Load HTML from a string
说明
$source [,
int $options = 0 ] ) :
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 PHP 5.4.0 and Libxml 2.6.0, you may also use the
optionsparameter 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
Example #1 Creating a Document
<?php
$doc = new DOMDocument();
$doc->loadHTML("<html><body>Test<br></body></html>");
echo $doc->saveHTML();
?>
