从外部网站获取DIV内容 [英] Get DIV content from external Website

问题描述

我想用纯PHP从外部网站获得DIV。

外部网站： http://www.isitdownrightnow.com/youtube.com.html

我想要的div文本isitdownrightnow（statusup div ）：< div class =statusup>该网站可能只是为您而停放......< / div>

我已经使用 DOMDocument 和 str_get_html file_get_contents $ c>，但我无法让它工作。

例如 $ b

  $ page = file_get_contents（'http： //css-tricks.com/forums/topic/jquery-selector-div-variable/'）; 
 $ doc = new DOMDocument（）; 
 $ doc-> loadHTML（$ page）; 
 $ divs = $ doc-> getElementsByTagName（'div'）; 
 foreach（$ divs as $ div）{
 //循环查找一个带有contentID的$ D $ 
 //然后回显其内容（赦免双关语）
 if（$ div-> getAttribute（'class'）==='bbp-template-notice'）{
 echo $ div-> nodeValue; 
 
 
 
 
 
 
 $ p $它只会在控制台显示一个错误： / p> 
 
 
 
 
无法加载资源：服务器响应的状态为500 
（内部服务器错误）
 
 
 
解决方案
这是我总是使用的： 
 
 
  $ url ='https://somedomain.com/somesite/'; 
 $ content = file_get_contents（$ url）; 
 $ first_step = explode（'< div id =thediv>'，$ content）; 
 $ second_step = explode（< / div>，$ first_step [1]）; 
 
 echo $ second_step [0]; 
  
 
I want to get a DIV from an external website with pure PHP.


External website: http://www.isitdownrightnow.com/youtube.com.html

Div text I want from isitdownrightnow (statusup div): <div class="statusup">The website is probably down just for you...</div>

I already tried file_get_contents with DOMDocument and str_get_html, but I could not get it to work. 

For example this
$page = file_get_contents('http://css-tricks.com/forums/topic/jquery-selector-div-variable/');
    $doc = new DOMDocument();
    $doc->loadHTML($page);
    $divs = $doc->getElementsByTagName('div');
    foreach($divs as $div) {
        // Loop through the DIVs looking for one withan id of "content"
        // Then echo out its contents (pardon the pun)
        if ($div->getAttribute('class') === 'bbp-template-notice') {
             echo $div->nodeValue;
        }
    }
It will just display an error in the console:

  
Failed to load resource: the server responded with a status of 500
  (Internal Server Error)

解决方案
This is what I always use:
$url = 'https://somedomain.com/somesite/';
$content = file_get_contents($url);
$first_step = explode( '<div id="thediv">' , $content );
$second_step = explode("</div>" , $first_step[1] );

echo $second_step[0];
