PHP code

function post_url($url, $post = "", $host = "www.ydtuiguang.com", $referrer = 'http://www.ydtuiguang.com/', $proxy = -1){    if(function_exists("curl_init")){        $ch = @curl_init();        @curl_setopt($ch, CURLOPT_URL, $url);        if(!empty($proxy["address"]))            @curl_setopt($ch, CURLOPT_PROXY, strpos($proxy["address"], "http") === 0 ? $proxy["address"] : "http://".$proxy["address"]);        if(!empty($proxy["account"]) && !empty($proxy["password"]))            @curl_setopt($ch, CURLOPT_PROXYUSERPWD, $proxy["account"].":".$proxy["password"]);        @curl_setopt($ch, CURLOPT_REFERER, $referrer);        @curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.0)");        @curl_setopt($ch, CURLOPT_COOKIEJAR, COOKIE_FILE_PATH);        @curl_setopt($ch, CURLOPT_COOKIEFILE, COOKIE_FILE_PATH);        @curl_setopt($ch, CURLOPT_HEADER, 0);        @curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);        @curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);        @curl_setopt($ch, CURLOPT_TIMEOUT, 1000);        if (!empty($post)) {            @curl_setopt($ch, CURLOPT_POST, 1);            @curl_setopt($ch, CURLOPT_POSTFIELDS, $post);        }        $result = @curl_exec($ch);        @curl_close($ch);    }elseif(function_exists("fsockopen")){        $httpheader = "POST ".$url."
