您好,我的输出 PHP 代码是:
Array ( [country] => BG - Bulgaria )
...他来自这里:
<?php
$ip = $_SERVER['REMOTE_ADDR'];
print_r(geoCheckIP($ip));
//Array ( [domain] => dslb-094-219-040-096.pools.arcor-ip.net [country] => DE - Germany [state] => Hessen [town] => Erzhausen )
//Get an array with geoip-infodata
function geoCheckIP($ip)
{
//check, if the provided ip is valid
if(!filter_var($ip, FILTER_VALIDATE_IP))
{
throw new InvalidArgumentException("IP is not valid");
}
//contact ip-server
$response=@file_get_contents('http://www.netip.de/search?query='.$ip);
if (empty($response))
{
throw new InvalidArgumentException("Error contacting Geo-IP-Server");
}
//Array containing all regex-patterns necessary to extract ip-geoinfo from page
$patterns=array();
$patterns["country"] = '#Country: (.*?) #i';
//Array where results will be stored
$ipInfo=array();
//check response from ipserver for above patterns
foreach ($patterns as $key => $pattern)
{
//store the result in array
$ipInfo[$key] = preg_match($pattern,$response,$value) && !empty($value[1]) ? $value[1] : '';
}
return $ipInfo;
}
?>
在我的案例“保加利亚”中,我怎样才能只获得国家的名称?我认为 preg_replace 或 substr 会发生这种情况,但我不知道现在更好的解决方案是什么。
