What is the best practice for passing variables and form data through a URL in PHP?

When passing variables and form data through a URL in PHP, it is best practice to use the GET method. This involves appending the data to the URL as key-value pairs. This method is commonly used for passing small amounts of data and is easily accessible and readable. 

// Example of passing variables through a URL using the GET method
$variable1 = 'value1';
$variable2 = 'value2';

$url = 'page.php?variable1=' . urlencode($variable1) . '&variable2=' . urlencode($variable2);

// Redirect to the URL with the variables
header('Location: ' . $url);
exit;
