PHP的curl常用的5个例子

下面是脚本之家 jb51.cc 通过网络收集整理的代码片段。

脚本之家小编现在分享给大家，也给大家做个参考。

1，抓取无访问控制文件

<?php 
     $ch= curl_init(); 
     curl_setopt($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

<?php 
     $ch= curl_init(); 
     curl_setopt($ch,"http://blog.51yip.com"); 
     curl_setopt($ch,1); 
     curl_setopt($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); 
     ?>

3，post数据后，抓取数据

<?php 
     $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'),'birth'=>'20101010')这样会报错的*/ 
     $data=array('name'=>'test','birth'=>'20101010'); 
     curl_setopt($ch,'http://localhost/mytest/curl/upload.php'); 
     curl_setopt($ch,CURLOPT_POST,CURLOPT_POSTFIELDS,$data); 
     curl_exec($ch); 
     ?>

4，抓取一些有页面访问控制的页面

<?php 
     $ch= curl_init(); 
     curl_setopt($ch,"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($ch,CURLOPT_USERPWD,'231144:2091XTAjmd='); 
     curl_setopt($ch,CURLOPT_HTTPGET,CURLOPT_REFERER,"http://club-china"); 
     curl_setopt($ch,0); 
     $result=curl_exec($ch); 
     curl_close($ch); 
     ?>

5，模拟登录到sina

<?php  
       
    functionchecklogin($user,$password) 
     { 
     if( emptyempty($user) || emptyempty($password) ) 
     { 
     return0; 
     } 
     $ch= curl_init( ); 
     curl_setopt($ch,"http://mail.sina.com.cn/index.html"); 
     curl_setopt($ch,true ); 
     curl_setopt($ch,CURLOPT_USERAGENT,USERAGENT ); 
     curl_setopt($ch,CURLOPT_COOKIEJAR,COOKIEJAR ); 
     curl_setopt($ch,CURLOPT_TIMEOUT,TIMEOUT ); 
     curl_setopt($ch,"http://mail.sina.com.cn/cgi-bin/login.cgi"); 
     curl_setopt($ch,"&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['HTTP_USER_AGENT'] ); 
     define("COOKIEJAR",tempnam("/tmp","cookie") ); 
     define("TIMEOUT",500 );  
       
     echochecklogin("zhangying215","xtaj227"); 
     ?> 
 
打开/tmp下面的cookie文件看一下
 
# Netscape HTTP Cookie File
# http://curl.haxx.se/rfc/cookie_spec.html
