| Description: I converted the Phoogle Maps into a helper for cakephp. Phoogle Maps Version 2.0: http://www.system7designs.com/codebase From his website: Phoogle Maps (pronounced like Foogle Maps) is a PHP class that integrates itself with the Google Maps API and with the geocoder.us database to make an easy to use interface to display Google Maps on your site. With about 5 lines of PHP code you can display a customized Google Map on your website. Please note that you will need a free Google Maps API Key ( http://www.google.com/apis/maps/signup.html ) to use Phoogle Maps. | |
