How to convert ip to city in php?

PHP IP address to city actual address:

What I use here Querying the actual IP address through http://www.cip.cc/ temporarily solved my problem (this method will become obsolete when the website http://www.cip.cc/ is discontinued, use with caution)

<?php
$ip = &#39;具体的IP地址&#39;;
$a = &#39;http://www.cip.cc/&#39;.$ip;
$opts = array(
    &#39;http&#39;=>array(
        &#39;method&#39;=>"GET",
        &#39;header&#39;=>
            "Accept-language: zh-cn\r\n" .
            "User-Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; 4399Box.560; .NET4.0C; .NET4.0E)" .
            "Accept: *//*"
    )
);
$ctx = stream_context_create($opts);
$x = file_get_contents($a,false,$ctx);
$result = get_tag_data($x,"pre");
function get_tag_data($html,$tag){
    $regex = "/<$tag>(.*?)<\/$tag>/is";
    preg_match_all($regex,$html,$matches,PREG_PATTERN_ORDER);
    return $matches[1];//返回值为数组 ,查找到的标签内的内容
}
