PHP的CURL方法curl_setopt()函数案例介绍(抓取网页,POST数据)

[php] view plain copy print?// 创建一个新cURL资源 $ch = curl_init();  // 设置URL和相应的选项 curl_setopt($ch, CURLOPT_URL, "http://www.baidu.com/"); curl_setopt($ch, CURLOPT_HEADER, false);  // 抓取URL并把它传递给浏览器 curl_exec($ch); //关闭cURL资源，并且释放系统资源 curl_close($ch); 

[php] view plain copy print?// 创建一个新cURL资源 $ch = curl_init(); $data = 'phone='. urlencode($phone); // 设置URL和相应的选项 curl_setopt($ch, CURLOPT_URL, "http://www.post.com/"); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, $data); // 抓取URL并把它传递给浏览器 curl_exec($ch); //关闭cURL资源，并且释放系统资源 curl_close($ch);
