What are some common challenges faced when working with GPS data in PHP, and how can they be overcome effectively?

Issue: One common challenge when working with GPS data in PHP is converting coordinates from one format to another, such as from degrees to decimal degrees. This conversion is necessary for many GPS-related calculations and mapping applications. Solution: To convert GPS coordinates from degrees to decimal degrees in PHP, you can use the following code snippet: 

function convertDegreesToDecimal($degrees, $minutes, $seconds, $direction) {
    $decimalDegrees = $degrees + ($minutes / 60) + ($seconds / 3600);
    
    if ($direction == 'S' || $direction == 'W') {
        $decimalDegrees = -$decimalDegrees;
    }
    
    return $decimalDegrees;
}

// Example usage
$latitudeDegrees = 37;
$latitudeMinutes = 45;
$latitudeSeconds = 12;
$latitudeDirection = 'N';

$longitudeDegrees = 122;
$longitudeMinutes = 25;
$longitudeSeconds = 48;
$longitudeDirection = 'W';

$latitudeDecimal = convertDegreesToDecimal($latitudeDegrees, $latitudeMinutes, $latitudeSeconds, $latitudeDirection);
$longitudeDecimal = convertDegreesToDecimal($longitudeDegrees, $longitudeMinutes, $longitudeSeconds, $longitudeDirection);

echo "Latitude: $latitudeDecimal, Longitude: $longitudeDecimal";
