PHP的curl常用的5个例子-PHP源码

// 1，抓取无访问控制文件

     $ch= curl_init(); 
     curl_setopt($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); 

// 2，使用代理进行抓取

     $ch= curl_init(); 
     curl_setopt($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, &＃39;user:password&＃39;);如果要密码的话，加上这个 
     $result=curl_exec($ch); 
     curl_close($ch); 

// 3，post数据后，抓取数据

     $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(&＃39;name&＃39;=>serialize(array(&＃39;tank&＃39;,&＃39;zhang&＃39;)),&＃39;sex&＃39;=>1,&＃39;birth&＃39;=>&＃39;20101010&＃39;)
     *例如array(&＃39;name&＃39;=>array(&＃39;tank&＃39;,&＃39;zhang&＃39;),&＃39;sex&＃39;=>1,&＃39;birth&＃39;=>&＃39;20101010&＃39;)这样会报错的*/ 
     $data=array(&＃39;name&＃39;=>&＃39;test&＃39;,&＃39;sex&＃39;=>1,&＃39;birth&＃39;=>&＃39;20101010&＃39;); 
     curl_setopt($ch, CURLOPT_URL,&＃39;http://localhost/mytest/curl/upload.php&＃39;); 
     curl_setopt($ch, CURLOPT_POST, 1); 
     curl_setopt($ch, CURLOPT_POSTFIELDS,$data); 
     curl_exec($ch); 

// 4.抓取一些有页面访问控制的页面

     $ch= curl_init(); 
     curl_setopt($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($ch, CURLOPT_USERPWD, &＃39;231144:2091XTAjmd=&＃39;); 
     curl_setopt($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); 

// 5.模拟登录到sina

    functionchecklogin($user,$password) 
     { 
     if( emptyempty($user) || emptyempty($password) ) 
     { 
     return0; 
     } 
     $ch= curl_init( ); 
     curl_setopt($ch, CURLOPT_REFERER,"http://mail.sina.com.cn/index.html"); 
     curl_setopt($ch, CURLOPT_HEADER, true ); 
     curl_setopt($ch, CURLOPT_RETURNTRANSFER, true ); 
     curl_setopt($ch, CURLOPT_USERAGENT, USERAGENT ); 
     curl_setopt($ch, CURLOPT_COOKIEJAR, COOKIEJAR ); 
     curl_setopt($ch, CURLOPT_TIMEOUT, TIMEOUT ); 
     curl_setopt($ch, CURLOPT_URL,"http://mail.sina.com.cn/cgi-bin/login.cgi"); 
     curl_setopt($ch, CURLOPT_POST, true ); 
     curl_setopt($ch, CURLOPT_POSTFIELDS,"&logintype=uid&u=".urlencode($user)."&psw=".$password); 
     $cOntents= curl_exec($ch); 
     curl_close($ch); 
     if( !preg_match("/Location: (.*)\\/cgi\\/index\\.php\\?check_time=(.*)\n/",$contents,$matches) ) 
     { 
     return0; 
     }else{ 
     return1; 
     } 
     }  
       
     define("USERAGENT",$_SERVER[&＃39;HTTP_USER_AGENT&＃39;] ); 
     define("COOKIEJAR", tempnam("/tmp","COOKIE") ); 
     define("TIMEOUT", 500 );  
       
     echochecklogin("zhangying215","xtaj227");
