What best practices should be followed when handling GPS data from a text file in PHP for real-time tracking?

When handling GPS data from a text file for real-time tracking in PHP, it is important to sanitize and validate the input data to prevent any security vulnerabilities. Additionally, you should parse the GPS coordinates from the text file and store them in a secure and efficient data structure, such as an array or database, for easy access during real-time tracking. Lastly, consider implementing error handling and logging mechanisms to troubleshoot any issues that may arise during the tracking process. 

// Read GPS data from a text file and store it in an array
$data = file_get_contents('gps_data.txt');
$lines = explode("\n", $data);

foreach ($lines as $line) {
    $gpsData = explode(',', $line);
    
    // Validate and sanitize GPS data
    $latitude = filter_var($gpsData[0], FILTER_VALIDATE_FLOAT);
    $longitude = filter_var($gpsData[1], FILTER_VALIDATE_FLOAT);
    
    // Store GPS data in a secure data structure for real-time tracking
    $gpsCoordinates[] = ['latitude' => $latitude, 'longitude' => $longitude];
}
