Hi Joseph,
it is the problem of using list(..) = each
Each - Return the current key and value pair from an array and advance the
array cursor
So your list($lat,$lng) = each($coords) will assign $lat = 0 and $lng =
($lat you passed), creating the weird output. Changing the function to as
shown below should clear your woes.
function nextCoord($coords, $usedCoords)
{
$lat = (float)$coords[0];
$lng = (float)$coords[1];
if(in_array($lat.':'.$lng, $usedCoords))
{
$lat += 0.0005;
$lng += 0.0005;
return nextCoord(array($lat, $lng), $usedCoords );
}
$array = array($lat, $lng);
print_r($array); // disable this after debug
// return $array; // enable this after debug
}
