?> [/code]

[size=4]Useage[/size] The following code shows how to use:

[code] $this->load->library('geolocater'); $obj_geolocation = $this->geolocater->getlocation('192.168.1.1', TRUE); [/code]

The 2 params are ('STRING:IP ADDRESS', 'BOOLEAN:GET CITY'). By default the class always gets the country.
