What potential pitfalls should be considered when using PHP to handle geographical coordinates conversion?

One potential pitfall when using PHP to handle geographical coordinates conversion is the risk of inaccurate results due to rounding errors in floating-point arithmetic. To mitigate this issue, it is recommended to use a library or function that provides precise calculations for geographical coordinates conversion. 

// Example using the PHP Geodesy library for precise geographical coordinates conversion
require 'vendor/autoload.php';

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

$coordinate1 = new Coordinate(37.774929, -122.419416); // San Francisco coordinates
$coordinate2 = new Coordinate(34.052235, -118.243683); // Los Angeles coordinates

$vincenty = new Vincenty();
$distance = $vincenty->getDistance($coordinate1, $coordinate2);

echo "Distance between San Francisco and Los Angeles: " . $distance . " meters";
