PHP CURL模拟GET及POST函数

    <?php   
    function vcurl($url, $post = '', $cookie = '', $cookiejar = '', $referer = ''){   
        $tmpInfo = '';   
        $cookiepath = getcwd().'./'.$cookiejar;   
        $curl = curl_init();   
        curl_setopt($curl, CURLOPT_URL, $url);   
        curl_setopt($curl, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);   
        if($referer) {   
        curl_setopt($curl, CURLOPT_REFERER, $referer);   
        } else {   
        curl_setopt($curl, CURLOPT_AUTOREFERER, 1);    
        }   
        if($post) {   
        curl_setopt($curl, CURLOPT_POST, 1);    
        curl_setopt($curl, CURLOPT_POSTFIELDS, $post);   
        }   
        if($cookie) {   
        curl_setopt($curl, CURLOPT_COOKIE, $cookie);   
        }   
        if($cookiejar) {   
        curl_setopt($curl, CURLOPT_COOKIEJAR, $cookiepath);   
        curl_setopt($curl, CURLOPT_COOKIEFILE, $cookiepath);   
        }   
        //curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);   
        curl_setopt($curl, CURLOPT_TIMEOUT, 100);   
        curl_setopt($curl, CURLOPT_HEADER, 0);   
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);   
        $tmpInfo = curl_exec($curl);   
        if (curl_errno($curl)) {   
           echo '<pre><b>错误:</b><br />'.curl_error($curl);   
        }   
        curl_close($curl);   
        return $tmpInfo;   
    }   
    ?> 
新版函数，更加简洁了，HOHO！
