Description:
------------
Using sqlite3, create a function to do a comparison
(SQLite3::createFunction)
Then query a table using the function.
Only one result is returned when multiple results would be expected.
Test script:
---------------
// callback function for use by the sqlite3 class which returns the
distance between 2 points on the earth
function SqLDistance($Latitude,$Longitude,$Lat,$Long)
{
$result = 10000.0; // flag to be off the earth!
if (isset($Latitude) && isset($Longitude))
{
$lat1rad = $Latitude * 0.01745327;// degrees * pi over
180
$lat2rad = $Lat * 0.01745327;// degrees * pi over 180
$long1rad = $Longitude * 0.01745327;// degrees * pi
over 180
$long2rad = $Long * 0.01745327;// degrees * pi over
180
// apply the spherical law of cosines to our
$earthRadius = 6378.1; //km
$result = $earthRadius *
acos(sin($lat1rad) * sin($lat2rad) +
cos($lat1rad) * cos($lat2rad) * cos($long2rad - $long1rad));
}
return $result;
}
class MyDB extends SQLite3
{
function __construct()
{
$this->open('zipcode.db');
$this->createFunction('Distance','SqlDistance',4);
}
function Borked($lat,$long,$count)
{
$result = $this->query("Select *,Distance(Lat,Long,$lat,$long)
as Distance from agents order by Distance Limit 0,$count");
return $result->fetchArray();
}
}
Expected result:
----------------
An array of results with a length greater then 1.
Actual result:
--------------
An array of result.
