调用方法:
$iploca = new ip_location;
$iploca -> init();
$iploca -> getiplocation($ip);
$area['country'] = str_replace(array('CZ88.NET'), '', $iploca -> get('country'));
$area['area'] = str_replace(array('CZ88.NET'), '', $iploca -> get('area'));
$area['country']=='' $area['country']='未知';
$area['area']=='' $area['area']='未知';
return $area;
如何使用php获取本机IP地址function ip() {
if(getenv('HTTP_CLIENT_IP') strcasecmp(getenv('HTTP_CLIENT_IP'), 'unknown')) {
$ip = getenv('HTTP_CLIENT_IP');
} elseif(getenv('HTTP_X_FORWARDED_FOR') strcasecmp(getenv('HTTP_X_FORWARDED_FOR'), 'unknown')) {
$ip = getenv('HTTP_X_FORWARDED_FOR');
} elseif(getenv('REMOTE_ADDR') strcasecmp(getenv('REMOTE_ADDR'), 'unknown')) {
$ip = getenv('REMOTE_ADDR');
} elseif(isset($_SERVER['REMOTE_ADDR']) $_SERVER['REMOTE_ADDR'] strcasecmp($_SERVER['REMOTE_ADDR'], 'unknown')) {
$ip = $_SERVER['REMOTE_ADDR'];
}
return preg_match ( '/[\d\.]{7,15}/', $ip, $matches ) ? $matches [0] : '';
}
以上函数取自phpcms的获取ip方法
PHP如何获取外网IP地址，类似于百度查询到的IP，网上的方法，查询到的都是局域网（内网）的IP，发一个函数给你.
/**
* 获取客户端IP地址
* @param integer $type 返回类型 0 返回IP地址 1 返回IPV4地址数字
* @param boolean $adv 是否进行高级模式获取（有可能被伪装）
* @return mixed
*/
function get_client_ip($type = 0,$adv=false) {
$type = $type ? 1 : 0;
static $ip = NULL;
if ($ip !== NULL) return $ip[$type];
if($adv){
if (isset($_SERVER['HTTP_X_FORWARDED_FOR'])) {
$arr = explode(',', $_SERVER['HTTP_X_FORWARDED_FOR']);
$pos = array_search('unknown',$arr);
if(false !== $pos) unset($arr[$pos]);
$ip = trim($arr[0]);
}elseif (isset($_SERVER['HTTP_CLIENT_IP'])) {
$ip = $_SERVER['HTTP_CLIENT_IP'];
}elseif (isset($_SERVER['REMOTE_ADDR'])) {
$ip = $_SERVER['REMOTE_ADDR'];
}
}elseif (isset($_SERVER['REMOTE_ADDR'])) {
$ip = $_SERVER['REMOTE_ADDR'];
}
// IP地址合法验证
$long = sprintf("%u",ip2long($ip));
$ip = $long ? array($ip, $long) : array('0.0.0.0', 0);
return $ip[$type];
}
如果是本地测试的话,获取到的是127.0.0.1
