Php uses the Sina interface to query the ip address to obtain the geographic location example

Copy codeThe Code is as follows:
<? Php
Function getIPLoc_sina ($ queryIP ){
$ Url = 'HTTP: // int.dpool.sina.com.cn/iplookup/iplookup.php? Format = json & ip = '. $ queryIP;
$ Ch = curl_init ($ url );
Curl_setopt ($ ch, CURLOPT_ENCODING, 'utf8 ');
Curl_setopt ($ ch, CURLOPT_TIMEOUT, 5 );
Curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, true); // get data and return
$ Location = curl_exec ($ ch );
$ Location = json_decode ($ location );
Curl_close ($ ch );
$ Loc = "";
If ($ location = FALSE) return "";
If (empty ($ location-> desc )){
$ Loc = $ location-> province. $ location-> city. $ location-> district. $ location-> isp;
} Else {$ loc = $ location-> desc;
}
Return $ loc;
}
Echo getIPLoc_sina ("183.37.209.57 ");
?>
