PHP根据IP查找地区

function GetIpLookup($ip = ‘‘){  
    if(empty($ip)){  
        $ip = GetIp();  
    }  
    $res = @file_get_contents(‘http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=js&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);
