If you're looking for a real-time solution without polling, you might find https://www.pulsestracker.com useful.

It provides real-time tracking via WebSockets & UDP and has built-in geofencing support.

Instead of checking location on every request, you define geofences, and Pulsestracker notifies your backend instantly when a device enters or exits.

This can be especially helpful for logistics, asset tracking, or live location-based triggers.

Would love to hear your thoughts on integrating it with your setup! 🚀

Here's a sample code to check if a given latitude and longitude fall within a radius in a Laravel Collection:

phpCopy codeuse Illuminate\Support\Facades\DB;
use Illuminate\Support\Collection;

public function checkLocationInCollection($inputLatitude, $inputLongitude, Collection $locations)
{
    foreach ($locations as $location) {
        $distance = $this->calculateDistance($inputLatitude, $inputLongitude, $location->latitude, $location->longitude);

        if ($distance <= $location->radius) {
            return true;
        }
    }

    return false;
}

private function calculateDistance($lat1, $long1, $lat2, $long2)
{
    $earthRadius = 3959;
    $latFrom = deg2rad($lat1);
    $longFrom = deg2rad($long1);
    $latTo = deg2rad($lat2);
    $longTo = deg2rad($long2);
    $latDelta = $latTo - $latFrom;
    $longDelta = $longTo - $longFrom;

    $angle = 2 * asin(sqrt(pow(sin($latDelta / 2), 2) + cos($latFrom) * cos($latTo) * pow(sin($longDelta / 2), 2)));
    $distance = $angle * $earthRadius;

    return $distance;
}

In this example, the checkLocationInCollection function takes in the input latitude, longitude, and a Collection of locations, each containing latitude, longitude, and radius properties. The function iterates through each location in the Collection and calculates the distance between the input latitude and longitude and the location using the calculateDistance function. If the calculated distance is less than or equal to the location's radius, the function returns true. If no location in the Collection meets the criteria, the function returns false.
