IP Lookup in PHP

Get the geolocation (geographic location) of an IP address with an API. The example below uses json as the output format. To switch to a different format, replace json in the URL path below with other supported formats like csv, xml, yaml & jsonp.

$ip  = '8.8.8.8';
$loc = file_get_contents('https://ipapi.co/'.$ip.'/json/');
echo $loc;
复制

Output

{
    "ip": "8.8.8.8",
    "city": "Mountain View",
    "region": "California",
    "region_code": "CA",
    "country": "US",
    "country_name": "United States",
    "continent_code": "NA",
    "in_eu": false,
    "postal": "94035",
    "latitude": 37.386,
    "longitude": -122.0838,
    "timezone": "America/Los_Angeles",
    "utc_offset": "-0700",
    "country_calling_code": "+1",
