CodeIgniter：帮助从网页获取元标记的类/库？ [英] CodeIgniter: A Class/Library to help get meta tags from a web page?

问题描述

我使用codeigniter。我想使用哪个php框架无关紧要。

I am using codeigniter. I guess it doesn't matter which php framework I am using.

但在我写我自己的类之前，还有一个已经写的，允许用户得到

But before I write my own class is there another that has already been written that allows a user to get the page title and meta tags (keywords, descriptions) of any sit...if they have any.

任何类型的PHP类都能做到这一点。

Any sort of PHP class that does that would be great.

感谢所有

推荐答案

PHP Simple HTML DOM 它的工作方式如下：

include('simple_html_dom.php');
$html = file_get_html('http://www.codeigniter.com/');

echo $html->find('title', 0)->innertext; // get <title>

echo "<pre>";
foreach($html->find('meta') as $element)
       echo $element->name . " : " . $element->content  . '<br>'; //prints every META tag

echo "</pre>";
