php curl常用的5个经典例子

 $ch= curl_init();

 curl_setopt($ch, CURLOPT_URL,"http://localhost/mytest/phpinfo.php");

 curl_setopt($ch, CURLOPT_HEADER, false);

 curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//如果把这行注释掉的话，就会直接输出

 $result=curl_exec($ch);

 curl_close($ch);

 ?>

 $ch= curl_init();
 curl_setopt($ch, CURLOPT_URL,"http://blog.51yip.com");
 curl_setopt($ch, CURLOPT_HEADER, false);
 curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
 curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, TRUE);
 curl_setopt($ch, CURLOPT_PROXY, 125.21.23.6:8080);
 //url_setopt($ch, CURLOPT_PROXYUSERPWD, 'user:password');如果要密码的话，加上这个
 $result=curl_exec($ch);
 curl_close($ch);
 ?>

 $ch= curl_init();

 /*在这里需要注意的是，要提交的数据不能是二维数组或者更高

 *例如array('name'=>serialize(array('tank','zhang')),'sex'=>1,'birth'=>'20101010')

 *例如array('name'=>array('tank','zhang'),'sex'=>1,'birth'=>'20101010')这样会报错的*/

 $data=array('name'=>'test','sex'=>1,'birth'=>'20101010');

 curl_setopt($ch, CURLOPT_URL,'http://localhost/mytest/curl/upload.php');

 curl_setopt($ch, CURLOPT_POST, 1);

 curl_setopt($ch, CURLOPT_POSTFIELDS,$data);

 curl_exec($ch);

 ?>

 $ch= curl_init();

 curl_setopt($ch, CURLOPT_URL,"http://club-china");

 /*CURLOPT_USERPWD主要用来破解页面访问控制的

 *例如平时我们所以htpasswd产生页面控制等。*/

 //curl_setopt($ch, CURLOPT_USERPWD, 'user:password');

 curl_setopt($ch, CURLOPT_HTTPGET, 1);

 curl_setopt($ch, CURLOPT_REFERER,"http://club-china");

 curl_setopt($ch, CURLOPT_HEADER, 0);

 $result=curl_exec($ch);

 curl_close($ch);
