Check bound latlng in special bound

Hi
I have specified bound(west,north-east-south) that need to check latlng in this bound
My code is:

PHP Code:

function inBounds($pointLat, $pointLong, $boundsNElat, $boundsNElong, $boundsSWlat, $boundsSWlong) {

        $eastBound = $pointLong < $boundsNElong;
        $westBound = $pointLong > $boundsSWlong;

        if ($boundsNElong < $boundsSWlong) {
            $inLong = $eastBound || $westBound;
        } else {
            $inLong = $eastBound && $westBound;
        }

        $inLat = $pointLat > $boundsSWlat && $pointLat < $boundsNElat;

        return (boolean)$inLat && $inLong;

    } 


But this code can only check latlng in north and south bound and not check from west to east
Do you can help me?
