Get all records from MySQL database that are within Google Maps .getBounds?

Question

Ok I have a database with about 1800 rows, each has a column lat and long, what I am trying to do, it query against Google Maps V3 .getBounds

Answer 1

We can find result between Maps.getBounds northEast and southWest latitude and northEast and southWest longitude using below query.

Search query should be between northEast.latitude AND southWest.latitude AND northEast.longitude AND southWest.longitude

$nelat=$_GET['nelat']-0.5;
$nelng=$_GET['nelng']-0.5;
$swlat=$_GET['swlat']-0.5;
$swlng=$_GET['swlng']-0.5;

$sql ="SELECT * FROM tablename where (CASE WHEN ".$nelat." < ".$swlat."
    THEN s.latitude BETWEEN ".$nelat." AND ".$swlat."
    ELSE s.latitude BETWEEN ".$swlat." AND ".$nelat."
END) 
AND
(CASE WHEN ".$nelng." < ".$swlng."
        THEN s.longitude BETWEEN ".$nelng." AND ".$swlng."
        ELSE s.longitude BETWEEN ".$swlng." AND ".$nelng."
END)";
