从HTML中提取电话号码

Question

我想从网站上提取电话号码，但最后我收到了错误消息。

Error: Notice: Trying to get property of non-object in C:\xampp\htdocs\testing.php on line 15  

我的代码如下：

$ch=curl_init("http://www.mudah.my/LG+G+Pro+2+D838+16GB+5+9in+2+26GHz+3GB+RAM+NEW+SET-30256077.htm");

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
$cl = curl_exec($ch);

$dom = new DOMDocument();

@$dom->loadHTML($cl);

$xpath = new DOMXpath($dom);

$phoneNo = $xpath->query("//div[@class='contact-phoneno']/text()");

$phone = $phoneNo->item(0)->nodeValue;

echo $phone;

Answer 1

使用：

$phoneNo = $xpath->query("//div[@class='contact-phoneno']");
$phone = $phoneNo->item(0)->textContent;

我获得了：013611xxxx
