        if (curl_errno($ch)) {//7.如果出错

        return $tmpInfo;  
    }  
    $data=array('name' => '1234');  
    $url="http://www.sohu.com/";  
      
    $method="GET";  //post或者get
    $file=curlPost($url,$data,$method);  
    $file=mb_convert_encoding($file,'UTF-8','GBK');  
    echo $file;

以下是模拟登陆的代码

    <?php  
        $cookie_file = tempnam('./temp','cookie');  
        function weixinPost($url,$data,$method,$setcooke=false,$cookie_file=false){  
            $ch = curl_init();   //1.初始化  
            curl_setopt($ch, CURLOPT_URL, $url); //2.请求地址  
            curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $method);//3.请求方式  
            //4.参数如下      
            curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);  
            curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);  
            curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (compatible; MSIE 5.01; Windows NT 5.0)');  
            curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);  
            curl_setopt($ch, CURLOPT_AUTOREFERER, 1);  
              
            if($method=="POST"){//5.post方式的时候添加数据     
                curl_setopt($ch, CURLOPT_POSTFIELDS, $data);  
            }  
            if($setcooke==true){  
                curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file);  
            }else{  
                curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file);  
            }  
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);  
            $tmpInfo = curl_exec($ch);//6.执行  
      
            if (curl_errno($ch)) {//7.如果出错  
                return curl_error($ch);  
            }  
            curl_close($ch);//8.关闭  
            return $tmpInfo;  
        }  
        $data=array('username' => '***','password'=>'***');  
        $url="http://www.xinxinj.com/login.php";  
        $method="POST";  
        $file=weixinPost($url,$data,$method,true,$cookie_file);  
        echo $file;  
              
        $url="http://www.xinxinj.com/admin.php";  
        $method="GET";  
        $file=weixinPost($url,$data,$method,false,$cookie_file);  
        echo $file;  
              
    ?>

网上的很多模拟登录程序，大都是通过服务程序apache之类的运行，获取到验证码之后显示在网页上，然后填上再POST出去

本文提供了一个程序实例，思路就是获取到验证码之后把验证码存储为一个图片，然后程序休眠20秒，在20秒之后由用户手动查看图片，并把验证码填写到code.txt文件中，20秒休眠完成后，程序会读code.txt的验证码，这样再带着验证码进行登录操作。具体代码如下：

/**
 * 模拟登录
 */
 
//初始化变量
$cookie_file = "tmp.cookie";
$login_url = "http://xxx.com/logon.php";
$verify_code_url = "http://xxx.com/verifyCode.php";
 
echo "正在获取COOKIE...\n";
$curlj = curl_init();
$timeout = 5;
curl_setopt($curl, CURLOPT_URL, $login_url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, $timeout);
curl_setopt($curl,CURLOPT_COOKIEJAR,$cookie_file); //获取COOKIE并存储
$contents = curl_exec($curl);
curl_close($curl);
 
echo "COOKIE获取完成，正在取验证码...\n";
//取出验证码
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $verify_code_url);
curl_setopt($curl, CURLOPT_COOKIEFILE, $cookie_file);
curl_setopt($curl, CURLOPT_HEADER, 0);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$img = curl_exec($curl);
curl_close($curl);
 
$fp = fopen("verifyCode.jpg","w");
fwrite($fp,$img);
fclose($fp);
echo "验证码取出完成，正在休眠，20秒内请把验证码填入code.txt并保存\n";
//停止运行20秒
sleep(20);
 
echo "休眠完成，开始取验证码...\n";
$code = file_get_contents("code.txt");
echo "验证码成功取出：$code\n";
echo "正在准备模拟登录...\n";
 
$post = "username=maben&pwd=hahahaha&verifycode=$code";
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER,1);
curl_setopt($curl, CURLOPT_POSTFIELDS, $post);
curl_setopt($curl, CURLOPT_COOKIEFILE, $cookie_file);
$result=curl_exec($curl);
curl_close($curl);
 
//这一块根据自己抓包获取到的网站上的数据来做判断
if(substr_count($result,"登录成功")){
 echo "登录成功\n";
}else{
 echo "登录失败\n";
 exit;
}
 
//OK，开始做你想做的事吧。。。。。
