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($ch); 
46  
47 // 5.模拟登录到sina
48  
49     functionchecklogin($user,$password) 
50      { 
51      if( emptyempty($user) || emptyempty($password) ) 
52      { 
53      return0; 
54      } 
55      $ch= curl_init( ); 
56      curl_setopt($ch, CURLOPT_REFERER,"http://mail.sina.com.cn/index.html"); 
57      curl_setopt($ch, CURLOPT_HEADER, true ); 
58      curl_setopt($ch, CURLOPT_RETURNTRANSFER, true ); 
59      curl_setopt($ch, CURLOPT_USERAGENT, USERAGENT ); 
60      curl_setopt($ch, CURLOPT_COOKIEJAR, COOKIEJAR ); 
61      curl_setopt($ch, CURLOPT_TIMEOUT, TIMEOUT ); 
62      curl_setopt($ch, CURLOPT_URL,"http://mail.sina.com.cn/cgi-bin/login.cgi"); 
63      curl_setopt($ch, CURLOPT_POST, true ); 
64      curl_setopt($ch, CURLOPT_POSTFIELDS,"&logintype=uid&u=".urlencode($user)."&psw=".$password); 
65      $contents= curl_exec($ch); 
66      curl_close($ch); 
67      if( !preg_match("/Location: (.*)\\/cgi\\/index\\.php\\?check_time=(.*)\n/",$contents,$matches) ) 
68      { 
69      return0; 
70      }else{ 
71      return1; 
72      } 
73      }  
74
