This is from a site of mine. In an example that I tested, the outcome of
$vanposlat was 52.133333. $zoekafstand = 15. The result of $zoekafstand /
(69 * 1.61) = 0,1350256. And surprise surprse $maxlat = 52.1350256???? So we
lost the 0.133333???? However when I echo $vanposlat it = 52.133333, but if
I do whatever calculation with it, you calculate only with 52??????
Any suggestions?
$url = "
http://maps.googleapis.com/maps/api/geocode/xml?address=".urlencode($zoekpos)."&sensor=false";
$geo = new SimpleXMLElement(file_get_contents($url));
if ($geo->status == "OK") {
$vanposlat = $geo->result->geometry->location->lat;
$vanposlng = $geo->result->geometry->location->lng;
$maxlat = $vanposlat + ( $zoekafstand / (69 * 1.61)); // 69 miles per
degree of latitude
