What is the process of parsing a GPX waypoint file using PHP?

To parse a GPX waypoint file using PHP, you can use PHP's SimpleXML extension to easily read and extract the data from the XML file. You can iterate through the waypoints and access their attributes such as latitude and longitude. 

$xml = simplexml_load_file('waypoints.gpx');

foreach ($xml->wpt as $waypoint) {
    $lat = (float) $waypoint['lat'];
    $lon = (float) $waypoint['lon'];
    echo "Latitude: $lat, Longitude: $lon" . PHP_EOL;
}
