Is storing coordinates in a PHP session a recommended practice for passing values between PHP pages, and how can this be implemented effectively?

Storing coordinates in a PHP session can be a recommended practice for passing values between PHP pages, especially if the coordinates need to persist across multiple page loads. To implement this effectively, you can store the coordinates in the $_SESSION superglobal array and access them on subsequent pages by starting the session and retrieving the values from the array. 

<?php
// Start the session
session_start();

// Store coordinates in the session
$_SESSION['coordinates'] = ['latitude' => 40.7128, 'longitude' => -74.0060];

// Access coordinates on another page
$latitude = $_SESSION['coordinates']['latitude'];
$longitude = $_SESSION['coordinates']['longitude'];

// Output the coordinates
echo "Latitude: $latitude, Longitude: $longitude";
?>
