Hi
Thanks for your reply. I am sending my code.
Please suggest me if anything is wrong in code
Function to calculate distance
function caldis($addr,$addr1)
{
require_once('lib/GoogleMapAPI.class.php');
$map = new GoogleMapAPI('map');
$map->setAPIKey('ABQIAAAAE-W_Pw2S_cQFTXQPeqAN5hSRhJXTRu3fM0ElVXnwviTojdgwfBSFyasfUJBRe0fV-qRt2uYLyHYkbA');
$geocode = $map->geoGetCoords($addr);
//print_r($geocode);
$lat= $geocode['lat'];
$lon= $geocode['lon'];
$geocode = $map->geoGetCoords($addr1);
$lat1= $geocode['lat'];
$lon1= $geocode['lon'];
/*echo $addr.$addr1;
echo $lat.$lon.$lat1.$lon1;*/
//M-Miles
$distance = $map->geoGetDistance($lat,$lon,$lat1,$lon1,M);
return $distance;
}
