In what scenarios should GET method be preferred over POST method for passing variables between PHP pages?

The GET method should be preferred over the POST method when passing variables between PHP pages if the data being sent is not sensitive or confidential, and if the data is being used to retrieve information rather than modify or update it. GET method appends data to the URL, making it visible to users and easily bookmarked or shared. 

// Using GET method to pass variables between PHP pages
// Page 1: sending data
$variable = "example";
<a href="page2.php?data=<?php echo $variable; ?>">Go to Page 2</a>

// Page 2: receiving data
$data = $_GET['data'];
echo $data;
