How can you pass a variable value from one PHP script to another using a link?

To pass a variable value from one PHP script to another using a link, you can append the variable and its value to the URL as query parameters. In the receiving script, you can retrieve the variable value from the URL using the $_GET superglobal array. Example PHP code snippet: 

// Sending script (script1.php)
$variable = "example";
echo "<a href='script2.php?var=$variable'>Click here</a>";

// Receiving script (script2.php)
if(isset($_GET['var'])){
    $received_variable = $_GET['var'];
    echo "Received variable value: " . $received_variable;
}
