php 怎么通过ip来获取所在位置
echo getcposition(getIP());
function getIP(){
if (isset($_SERVER)) {
if (isset($_SERVER[HTTP_X_FORWARDED_FOR])) {
$realip = $_SERVER[HTTP_X_FORWARDED_FOR];
} elseif (isset($_SERVER[HTTP_CLIENT_IP])) {

if (getenv("HTTP_X_FORWARDED_FOR")) {
$realip = getenv( "HTTP_X_FORWARDED_FOR");
} elseif (getenv("HTTP_CLIENT_IP")) {
$realip = getenv("HTTP_CLIENT_IP");
} else {
$realip = getenv("REMOTE_ADDR");
}
}
return $realip;
}
function getcposition($ip){
$res1 = file_get_contents("");
$res1 = json_decode($res1,true);
//print_r($res1);
if ($res1[ "code"]==0){
return $res1['data']["country"].$res1['data'][ "region"].$res1['data']["city"]."_".$res1['data'][ "isp"];
}else{
return "未知";

php 怎么获取记录ip所在地
?php
header('Content-Type:text/html;Charset=utf-8');
function GetIp(){
$realip = '';
$unknown = 'unknown';
if (isset($_SERVER)){
if(isset($_SERVER['HTTP_X_FORWARDED_FOR']) !empty($_SERVER['HTTP_X_FORWARDED_FOR']) strcasecmp($_SERVER['HTTP_X_FORWARDED_FOR'], $unknown)){
$arr = explode(',', $_SERVER['HTTP_X_FORWARDED_FOR']);
foreach($arr as $ip){

$realip = $ip;
break;

$realip = $_SERVER['HTTP_CLIENT_IP'];
}else if(isset($_SERVER['REMOTE_ADDR']) !empty($_SERVER['REMOTE_ADDR']) strcasecmp($_SERVER['REMOTE_ADDR'], $unknown)){
$realip = $_SERVER['REMOTE_ADDR'];
}else{
$realip = $unknown;
}
}else{
if(getenv('HTTP_X_FORWARDED_FOR') strcasecmp(getenv('HTTP_X_FORWARDED_FOR'), $unknown)){
$realip = getenv("HTTP_X_FORWARDED_FOR");

}else if(getenv('REMOTE_ADDR') strcasecmp(getenv('REMOTE_ADDR'), $unknown)){
$realip = getenv("REMOTE_ADDR");
}else{
$realip = $unknown;
}
}
$realip = preg_match("/[d.]{7,15}/", $realip, $matches) ? $matches[0] : $unknown;
return $realip;
}
function GetIpLookup($ip = ''){
if(empty($ip)){
$ip = GetIp();
}
$res = @file_get_contents(';ip=' . $ip);
if(empty($res)){ return false; }
$jsonMatches = array();
preg_match('#{.+?}#', $res, $jsonMatches);
if(!isset($jsonMatches[0])){ return false; }
$json = json_decode($jsonMatches[0], true);
if(isset($json['ret']) $json['ret'] == 1){
$json['ip'] = $ip;
unset($json['ret']);
}else{
return false;
}
return $json;
}
$ipInfos = GetIpLookup('123.125.114.144'); //baidu.com IP地址
var_dump($ipInfos);
使用了新浪的开放API
PHP IP地址归属地查询的接口
function GetIpLookup($ip = ''){
$res = @file_get_contents(';ip=' . $ip);
if(empty($res)){ return false; }
$jsonMatches = array();
preg_match('#{.+?}#', $res, $jsonMatches);
if(!isset($jsonMatches[0])){ return false; }
$json = json_decode($jsonMatches[0], true);
if(isset($json['ret']) $json['ret'] == 1){
$json['ip'] = $ip;
unset($json['ret']);
}else{
return false;
}
return $json;
}
$ipInfos = $this-GetIpLookup('222.223.191.12'); //baidu.com IP地址
var_dump($ipInfos);

一下是cityadd.php的内容
?php

$luan = "六安市";
$bozhou = "亳州市";

上网下一个qqwry.dat
这几个文件放在一个文件夹,做一个页面里面放一个JS,并且调用第一个文件的函数,就可以了
script document.write(jstext)/script
