How can PHP variables be passed through URLs using $_GET?

To pass PHP variables through URLs using $_GET, you can append the variable name and value to the URL as key-value pairs separated by an equal sign. In the receiving PHP script, you can access these variables using the $_GET superglobal array. This method is commonly used to pass data between different pages or components in a web application. 

// Sending page
$variable = "example";
$url = "receiver.php?var=" . urlencode($variable);
echo "<a href='$url'>Click here to pass variable through URL</a>";

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