<?php
  $curl = curl_init();//初始化一个cURL对象
  $url = "http://cart.jd.com/cart/cart.html?backurl=http://item.jd.com/176166.html&rid=0.9533184533      938766";
  $header = array();
  $header[] = ‘User-Agent: 5.0 (iPhone; U; CPU iPhone OS 4_3 like Mac OS X; en-us)‘;
  $header[] = ‘Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8‘;
  $header[]= ‘Accept-Encoding: gzip,deflate‘;
  $header[]= ‘//可以根据需要增加header内容‘;
  curl_setopt($curl,CURLOPT_URL, $url);//设置你需要抓去的URL地址
  curl_setopt($curl,CURLOPT_HEADER,$header );//设置header
  curl_setopt($curl,CURLOPT_RETURNTRANSFER,1);//将结果返回输出到字符串
  $str = curl_exec($curl);运行cURL,请求网页

如何post数据

//假设我们去post一个表单到http://www.example.com/sendSMS.php
//提交内容 一个是电话号码，一个短信内容
<?php
 $phoneNumber = ‘13598785110‘;
 $message = ‘this is a test message about cURL to POST URL‘;
 $curlPost =   ‘pNUMBER=‘.$phoneNumber.‘&MESSAGE=‘.urlencode($message).‘&SUBMIT=Send‘;//拼接请求参数
 $url = ‘http://www.example.com/sendSMS.php‘;
 $header[] = ‘........‘;
 $curl = curl_init();
 curl_setopt($curl,CURLOPT_URL,$url);
 curl_setopt($curl,CURLOPT_HEADER,$header);
 curl_setopt($curl,CURLOPT_RETURNTRANSFER,1);
 curl_setopt($curl,CURLOPT_POST,1);//设置请求方式为post
 curl_seropt($curl,CURLOPT_POSTFIELDS,$curlPost);//设置post数据
 $data = curl_exec(curl);
 curl_close($curl)
