What are the best practices for passing variables via GET in PHP for frame management?

When passing variables via GET in PHP for frame management, it is important to properly sanitize and validate the data to prevent security vulnerabilities such as SQL injection attacks. One best practice is to use PHP's built-in filter_input function to retrieve and sanitize the variables from the GET request. 

// Retrieve and sanitize variables from GET request
$variable1 = filter_input(INPUT_GET, 'variable1', FILTER_SANITIZE_STRING);
$variable2 = filter_input(INPUT_GET, 'variable2', FILTER_SANITIZE_NUMBER_INT);

// Use the sanitized variables in your code
echo "Variable 1: " . $variable1;
echo "Variable 2: " . $variable2;
