Are there any specific PHP functions or libraries recommended for accurately converting geographical coordinates?

When working with geographical coordinates, it's important to accurately convert between different coordinate systems to ensure proper mapping and location-based functionality. One common approach is to use the PHP library called "geospatial-php" which provides functions for converting between various coordinate systems such as latitude/longitude and UTM. 

// Example of using the geospatial-php library to convert geographical coordinates

require_once('geospatial-php/vendor/autoload.php');

use Location\Coordinate;
use Location\Distance\Vincenty;

// Define the initial coordinates
$latitude = 37.7749; // Example latitude
$longitude = -122.4194; // Example longitude

// Create a Coordinate object
$coordinate = new Coordinate($latitude, $longitude);

// Convert the coordinates to UTM
$utmCoordinate = $coordinate->toUTM();

// Output the converted UTM coordinates
echo "UTM Easting: " . $utmCoordinate->getEasting() . ", Northing: " . $utmCoordinate->getNorthing();
