PHP Map + Location Plugin

PHP Map + Location Plugin

This is a collection of location based functions that can get a users location based on their ip address using the IPInfoDB api, return advanced details on a specific location with the Yahoo PlaceFinder api, or dynamically create maps (as images or with javascript) using the Google Maps api.

IP Location

This function interacts with the API to get a users location based on their IP address. It can return city, state, country, latitude & longitude and is accurate within a 25 mile radius. This function accepts an IP Address and returns an array of location based values.

$location = $location->ip ($_SERVER['REMOTE_ADDR']); // Values returned

Your IP Based Location

Country: United States Country Code: US State: Washington City: Kirkland Post Code: Latitude: 47.6966 Longitude: -122.197

See below on how to generate maps

Place Finder

This function uses the Yahoo PlaceFinder API to get detailed information about a specific location. This is the way to go if you want to get more detailed information or find a more exact location. It accepts a textual location (zip code, city/state, street address, latitude/longitude, etc) and returns an array of location based values.

$info = $location->info ('400 Broad St Seattle, WA 98109'); // Values returned

Country: United States Country Code: US State: Washington State Code: WA County: King County City: Seattle Post Code: 98109 Cross Street: Near the intersection of Broad St and John St House: 400 Street: Broad St Radius: 500 Quality: 87 Where on Earth ID: 12798953 Latitude: 47.619859 Longitude: -122.348749

Google Maps

Use this to automatically generate Google Maps for a specific location. This function accepts a number of parameters:

  • 1. location (required. options: latitude and longitude)
  • 2. format (options: javascript, jpg, jpg-baseline, png, png32, gif))
  • 3. map type (options: roadmap, hybrid, satellite, terrain)
  • 4. width (options: value in px or %)
  • 5. height (options: value in px or %)
  • 6. zoom level (options: number between 1 and 21)
  • 7. id (options: any valid css id)


Example 1 (Javascript)</

The first example uses javascript to generate a dynamic map. To generate a map with javascript you’ll need to pass both the latitude and longitude coordinates to the location parameter (the latidude and longitude can be retreived with either the ip location or place finder functions descriped above). The map is injected into a div with an id of “map_canvas” by default (whose height/width can be modified via css). If you want to set the width & height with css instead of via the function, pass “css” to both the width and height parameters.

$coordinates = $info['latitude'].','.$info['longitude'];
echo $location->map($coordinates, 'javascript', 'hybrid', '100%', '300px', '16', 'map_1');


Google Maps (Image)

Currently the map function in only able to add one javascript map per page. If you need multiple maps (or just want to generate an image instead) simply set the second parameter to the type of image you want returned (jpg, jpg-baseline, png, png32 or gif). You can set the dimensions to anything you like, but Google’s maximum allowed image size is 630 by 630 pixels. A few examples of different image settings follow…

echo $location->map($coordinates, 'png32', 'roadmap', '630px', '630px', '11', 'map_2');
echo $location->map($coordinates, 'jpg', 'satellite', '630px', '200px', '7', 'map_3');
echo $location->map($coordinates, 'gif', 'terrain', '200px', '200px', '5', 'map_4');
echo $location->map($coordinates, 'png', 'satellite', '630px', '200px', '1', 'map_5');
