// 设置你需要抓取的url
curl_setopt($curl, curlopt_url, 'http://bbs.it-home.org');
// 设置header
curl_setopt($curl, curlopt_header, 1);
// 设置curl 参数，要求结果保存到字符串中还是输出到屏幕上。
curl_setopt($curl, curlopt_returntransfer, 1);
// 运行curl，请求网页
$data = curl_exec($curl);
// 关闭url请求
curl_close($curl);
// 显示获得的数据

?>

例2: post数据 sendsms.php，其可以接受两个表单域，一个是电话号码，一个是短信内容。 post数据

$phonenumber　=　'13812345678';
$message　=　'this　message　was　generated　by　curl　and　php';
$curlpost　=　'pnumber='　.　urlencode($phonenumber)　.　'&message='　.　urlencode($message)　.　'&submit=send';
$ch　=　curl_init();
curl_setopt($ch,　curlopt_url,　'http://www.lxvoip.com/sendsms.php');
curl_setopt($ch,　curlopt_header,　1);
curl_setopt($ch,　curlopt_returntransfer,　1);
curl_setopt($ch,　curlopt_post,　1);
curl_setopt($ch,　curlopt_postfields,　$curlpost);
$data　=　curl_exec();
curl_close($ch);
?>

例3:使用代理服务器 使用代理服务器

$ch　=　curl_init();
curl_setopt($ch,　curlopt_url,　'http://bbs.it-home.org');
curl_setopt($ch,　curlopt_header,　1);
curl_setopt($ch,　curlopt_returntransfer,　1);
curl_setopt($ch,　curlopt_httpproxytunnel,　1);
curl_setopt($ch,　curlopt_proxy,　'proxy.lxvoip.com:1080');
curl_setopt($ch,　curlopt_proxyuserpwd,　'user:password');
$data　=　curl_exec();
curl_close($ch);
?>

例4: 模拟登录 curl 模拟登录 discuz 程序,适合dz7.0,将username改成你的用户名,userpass改成你的密码就可以了. curl 模拟登录 discuz 程序

!extension_loaded('curl') && die('the curl extension is not loaded.');

$discuz_url = 'http://www.lxvoip.com';//论坛地址 $login_url = $discuz_url .'/logging.php?action=login';//登录页地址 $get_url = $discuz_url .'/my.php?item=threads'; //我的帖子

$post_fields = array(); //以下两项不需要修改 $post_fields['loginfield'] = 'username'; $post_fields['loginsubmit'] = 'true'; //用户名和密码，必须填写 $post_fields['username'] = 'lxvoip'; $post_fields['password'] = '88888888'; //安全提问 $post_fields['questionid'] = 0; $post_fields['answer'] = ''; //@todo验证码 $post_fields['seccodeverify'] = '';

//获取表单formhash $ch = curl_init($login_url); curl_setopt($ch, curlopt_header, 0); curl_setopt($ch, curlopt_returntransfer, 1); $contents = curl_exec($ch); curl_close($ch); preg_match('//i', $contents, $matches); if(!empty($matches)) { $formhash = $matches[1]; } else { die('not found the forumhash.'); }

//post数据，获取cookie $cookie_file = dirname(__file__) . '/cookie.txt'; //$cookie_file = tempnam('/tmp'); $ch = curl_init($login_url); curl_setopt($ch, curlopt_header, 0); curl_setopt($ch, curlopt_returntransfer, 1); curl_setopt($ch, curlopt_post, 1); curl_setopt($ch, curlopt_postfields, $post_fields); curl_setopt($ch, curlopt_cookiejar, $cookie_file); curl_exec($ch); curl_close($ch);

//带着上面得到的cookie获取需要登录后才能查看的页面内容 $ch = curl_init($get_url); curl_setopt($ch, curlopt_header, 0); curl_setopt($ch, curlopt_returntransfer, 0); curl_setopt($ch, curlopt_cookiefile, $cookie_file); $contents = curl_exec($ch); curl_close($ch);

var_dump($contents);
