Get latitude and longitude values from your address

When you are integrating google maps for locations you may need to know their latitude and longitude values. In that time pass your address through maps.google.com for api request.It returns the values as json output. The values are stored into database. So next time you can search the location in table. If it is not found you can send api request and store it.Why we are store the values in database because to avoid of frequent usage this is free api even it has some limit of access. when we frequent request the server doesn’t respond immediately. So that’s why we store the values.

In php:

For example

$prepAddr="Atlanda";

$geocode=file_get_contents('http://maps.google.com/maps/api/geocode/json?address='.$prepAddr.'&sensor=false');

$output= json_decode($geocode);

$lat = $output->results[0]->geometry->location->lat;
$long = $output->results[0]->geometry->location->lng;

Database:

CREATE TABLE `test`.`geocode` (`location_id` INT(11) NOT NULL AUTO_INCREMENT PRIMARY KEY, `city_name` VARCHAR(255) NOT NULL, `latitude` VARCHAR(255) NOT NULL, `longitude` VARCHAR(255) NOT NULL, `status` TINYINT(2) NOT NULL DEFAULT '1' COMMENT '1-Active,0-Deactive') ENGINE = InnoDB;
