header('content-type:text/html;charset=utf-8');  
function curlPost($url,$data,$method){  
    $ch = curl_init();   //1.初始化  
    curl_setopt($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);//https  
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);  
    curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (compatible; MSIE 5.01; Windows NT 5.0)');//模拟浏览器  
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);  
    curl_setopt($ch, CURLOPT_AUTOREFERER, 1);  
        curl_setopt($ch, CURLOPT_HTTPHEADER,array('Accept-Encoding: gzip, deflate'));//gzip解压内容  
        curl_setopt($ch, CURLOPT_ENCODING, 'gzip,deflate');  
      
    if($method=="POST"){//5.post方式的时候添加数据  
        curl_setopt($ch, CURLOPT_POSTFIELDS, $data);  
    }  
    curl_setopt($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('name' => '1234');  
$url="http://www.sohu.com/";  
  
$method="GET";  
$file=curlPost($url,$data,$method);  
$file=mb_convert_encoding($file,'UTF-8','GBK');  
echo $file;

当cookie认证登陆的时候

<?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;
