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.
