What are the best practices for passing variables to the PHP interpreter in a CGI environment?

When passing variables to the PHP interpreter in a CGI environment, it is best practice to use the $_GET or $_POST superglobals to retrieve the variables from the URL or form submission. This ensures that the variables are securely passed to the PHP script and helps prevent security vulnerabilities such as SQL injection attacks. 

// Example of passing variables to PHP interpreter in a CGI environment using $_GET superglobal
$variable1 = $_GET['variable1'];
$variable2 = $_GET['variable2'];

// Use the variables in your PHP script
echo "Variable 1: " . $variable1 . "<br>";
echo "Variable 2: " . $variable2;
