PHP的curl常用的5种写法

 1 // 1，抓取无访问控制文件
 2
 3      $ch= curl_init();
 4      curl_setopt($ch, CURLOPT_URL,"http://localhost/mytest/phpinfo.php");
 5      curl_setopt($ch, CURLOPT_HEADER, false);
 6      curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//如果把这行注释掉的话，就会直接输出
 7      $result=curl_exec($ch);
 8      curl_close($ch);
 9
10 // 2，使用代理进行抓取
11
12      $ch= curl_init();
13      curl_setopt($ch, CURLOPT_URL,"http://blog.51yip.com");
14      curl_setopt($ch, CURLOPT_HEADER, false);
15      curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
16      curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, TRUE);
17      curl_setopt($ch, CURLOPT_PROXY, 125.21.23.6:8080);
18      //url_setopt($ch, CURLOPT_PROXYUSERPWD, ‘user:password‘);如果要密码的话，加上这个
19      $result=curl_exec($ch);
20      curl_close($ch);
21
22 // 3，post数据后，抓取数据
23
24      $ch= curl_init();
25      /*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
26      *例如array(‘name‘=>serialize(array(‘tank‘,‘zhang‘)),‘sex‘=>1,‘birth‘=>‘20101010‘)
27      *例如array(‘name‘=>array(‘tank‘,‘zhang‘),‘sex‘=>1,‘birth‘=>‘20101010‘)这样会报错的*/
28      $data=array(‘name‘=>‘test‘,‘sex‘=>1,‘birth‘=>‘20101010‘);
29      curl_setopt($ch, CURLOPT_URL,‘http://localhost/mytest/curl/upload.php‘);
30      curl_setopt($ch, CURLOPT_POST, 1);
31      curl_setopt($ch, CURLOPT_POSTFIELDS,$data);
32      curl_exec($ch);
33
34 // 4.抓取一些有页面访问控制的页面
35
36      $ch= curl_init();
37      curl_setopt($ch, CURLOPT_URL,"http://club-china");
38      /*CURLOPT_USERPWD主要用来破解页面访问控制的
39      *例如平时我们所以htpasswd产生页面控制等。*/
40      //curl_setopt($ch, CURLOPT_USERPWD, ‘231144:2091XTAjmd=‘);
41      curl_setopt($ch, CURLOPT_HTTPGET, 1);
42      curl_setopt($ch, CURLOPT_REFERER,"http://club-china");
43      curl_setopt($ch, CURLOPT_HEADER, 0);
44      $result=curl_exec($ch);
45      curl_close($ch);
46
