php 怎么通过ip来获取所在位置

echo  getcposition(getIP());

function getIP(){

php 怎么获取记录ip所在地

?php

}

function GetIpLookup($ip = ''){

if(empty($ip)){

$res = @file_get_contents(';ip=' . $ip);

$jsonMatches = array();

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);

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
