Questions:

i am new to Google map things. i have a table in which there are list of all the location( the location of super stores) with their Latitude and Longitude .

Now i want to know all possible location(may b Latitude and Longitude ) of these super stores that are within 10km radius of my current location.

I have no idea how i can do this using Google map (in php code).
What Google map API should i used ?
Any suggestion ,project code, information will be helpful for me

Thanks in Advance

Answer:

You can Use Following Query of Mysql to get all stores within specified miles

select * from stores where lat!='' and lng!='' and ( 3959 * acos( cos( radians(" . $centerpoints['lat'] . ") ) * cos( radians( lat ) ) * cos( radians( lng ) - radians(" . $centerpoints['lng'] . ") ) + sin( radians(" . $centerpoints['lat'] . ") ) * sin( radians( lat ) ) ) ) < " . $distanceInMile

Have a look at above. Should give you a good idea.

To find locations in your markers table that are within a certain
radius distance of a given latitude/longitude, you can use a SELECT
statement based on the Haversine formula. The Haversine formula is
used generally for computing great-circle distances between two pairs
of coordinates on a sphere. An in-depth mathemetical explanation is
given by Wikipedia and a good discussion of the formula as it relates
to programming is on Movable Type’s site.

Here’s the SQL statement that will find the closest 20 locations that
are within a radius of 25 miles to the 37, -122 coordinate. It
calculates the distance based on the latitude/longitude of that row
and the target latitude/longitude, and then asks for only rows where
the distance value is less than 25, orders the whole query by
distance, and limits it to 20 results. To search by kilometers instead
of miles, replace 3959 with 6371.
