我们先来看下个人常用的代码PHP

<?phpinclude_once('./qqwry.php');$QQWry=new QQWry;  function get_real_ip(){$ip=false;if(!empty($_SERVER["HTTP_CLIENT_IP"])){$ip = $_SERVER["HTTP_CLIENT_IP"];}if (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) {$ips = explode (", ", $_SERVER['HTTP_X_FORWARDED_FOR']);if ($ip) { array_unshift($ips, $ip); $ip = FALSE; }for ($i = 0; $i < count($ips); $i++) {if (!eregi ("^(10|172/.16|192/.168)/.", $ips[$i])) {$ip = $ips[$i];break;}}}return $ip;} function is_ip($str) {  $ip = explode(".", $str);  if (count($ip)<4 || count($ip)>4) return 0;  foreach($ip as $ip_addr) {    if ( !is_numeric($ip_addr) ) return 0;    if ( $ip_addr<0 || $ip_addr>255 ) return 0;  }  return 1;}  $ip=$_SERVER['REMOTE_ADDR']; $ifErr=$QQWry->QQWry($ip); $city = $QQWry->Country.$QQWry->Local; //echo $city;*/  if (strpos($city,'玄武区')!==false){  $city = "玄武区";}else if(strpos($city,'仙林')!==false){  $city = "仙林";}else if(strpos($city,'秦淮区')!==false){  $city = "秦淮区";}else if(strpos($city,'江宁')!==false){  $city = "江宁";}else if(strpos($city,'鼓楼')!==false){  $city = "鼓楼";}else{  $city = "栖霞";}if (isset($_GET['chengshi'])) { //Ê×ÏÈ¼ì²âÊÇ·ñ»ñµÃÁË GET ´«µÝµÄÊý¾Ý  setcookie("cookie_city",$_GET['chengshi'],time()+3600*24);$city = $_GET['chengshi']; } else if (isset($_COOKIE["cookie_city"])) { //¼ì²âÊÇ·ñ´æÔÚêÇ³ÆCookie  $city = $_COOKIE["cookie_city"]; //ÏÔÊ¾Cookie±£´æµÄÊý¾Ý } else {  setcookie("cookie_city",$city,time()+3600*24); //´¿³õÊ¼»¯´Ë±äÁ¿ $_COOKIE["cookie_city"] = $city;} ?>
