Php 从网站获取数据

我有自己的外部网站，我想从网站上获得一些数据。我使用CURL来获取网站的内容，但是我想要的部分是：

编辑：坦率地说，我想获得facebook页面的时间戳，如果您在页面上使用Inspect元素，您将看到如下代码：

<span class="fsm fwn fcg"><a class="_5pcq">
<abbr title="Tuesday, June 30, 2015 at 5:00pm" data-utime="1435663826" data-shorten="1" class="_5ptz timestamp livetimestamp">5 hrs</abbr></a>
<span class="fsm fwn fcg"><a class="_5pcq">
<abbr title="Tuesday, June 30, 2015 at 5:01pm" data-utime="1435663827" data-shorten="1" class="_5ptz timestamp livetimestamp">5 hrs</abbr></a>
<span class="fsm fwn fcg"><a class="_5pcq">
<abbr title="Tuesday, June 30, 2015 at 5:02pm" data-utime="1435663828" data-shorten="1" class="_5ptz timestamp livetimestamp">5 hrs</abbr></a>
<span class="fsm fwn fcg"><a class="_5pcq">
<abbr title="Tuesday, June 30, 2015 at 5:03pm" data-utime="1435663829" data-shorten="1" class="_5ptz timestamp livetimestamp">5 hrs</abbr></a>
<span class="fsm fwn fcg"><a class="_5pcq">
<abbr title="Tuesday, June 30, 2015 at 5:04pm" data-utime="1435663830" data-shorten="1" class="_5ptz timestamp livetimestamp">5 hrs</abbr></a>
</span>

您可以使用PHP对html文档的扩展，然后使用特定元素的实例。

如果您已经获得html标记，您可以

试试这个：

<?php 

$curl = curl_init('https://www.facebook.com/Rajnikant.Vs.CIDJokez'); 


curl_setopt($curl, CURLOPT_FAILONERROR, true); 
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true); 
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false); 
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);   
$result = curl_exec($curl); 
//echo $result; 

/* $result = 
'<span class="fsm fwn fcg"><a class="_5pcq">
<abbr title="Tuesday, June 30, 2015 at 5:00pm" data-utime="1435663826" data-shorten="1" class="_5ptz timestamp livetimestamp">5 hrs</abbr></a>
<span class="fsm fwn fcg"><a class="_5pcq">
<abbr title="Tuesday, June 30, 2015 at 5:01pm" data-utime="1435663827" data-shorten="1" class="_5ptz timestamp livetimestamp">5 hrs</abbr></a>
<span class="fsm fwn fcg"><a class="_5pcq">
<abbr title="Tuesday, June 30, 2015 at 5:02pm" data-utime="1435663828" data-shorten="1" class="_5ptz timestamp livetimestamp">5 hrs</abbr></a>
<span class="fsm fwn fcg"><a class="_5pcq">
<abbr title="Tuesday, June 30, 2015 at 5:03pm" data-utime="1435663829" data-shorten="1" class="_5ptz timestamp livetimestamp">5 hrs</abbr></a>
<span class="fsm fwn fcg"><a class="_5pcq">
<abbr title="Tuesday, June 30, 2015 at 5:04pm" data-utime="1435663830" data-shorten="1" class="_5ptz timestamp livetimestamp">5 hrs</abbr></a>
</span>';
*/
$html = $result;
$dom = new DOMDocument();

@$dom->loadHTML($html);
$a = $dom->getElementsByTagName('abbr');

$data = array();

for ($i=0; $i < $a->length; $i++) {
    $data[] = $a->item($i)->getAttribute('data-utime');

}

echo '<pre>';
print_r($data);
echo '</pre>';

我试了很多次。但这对我不起作用。就因为我是用CURL获取的吗？嗨，Jeff，你能给出完整的php吗。我可以帮你把它报废。这就是完整的PHP！！好吧，非常狂热地说，我想废弃一个facebook页面。并且想要得到第一页的时间戳。您显示的代码无效。页面是：如果您使用Inspect元素，那么您可以看到post的时间戳仍然不工作！！这对你有用吗？如果使用代码，则会显示错误“更新浏览器”
