What is the difference between formatting and encoding in the context of PHP variables for GET requests?

Formatting refers to how the data is structured or presented, while encoding involves converting data into a specific format for transmission or storage. In the context of PHP variables for GET requests, formatting may involve arranging the data in a specific way, such as separating key-value pairs with an equal sign and using ampersands to separate multiple parameters. Encoding, on the other hand, ensures that the data is properly encoded for safe transmission over the internet, such as using urlencode() to encode special characters. 

// Example of formatting and encoding PHP variables for GET requests
$data = array(
    'name' => 'John Doe',
    'age' => 30
);

// Formatting the data
$queryString = http_build_query($data);

// Encoding the formatted data for safe transmission
$encodedData = urlencode($queryString);

// Output the encoded data
echo $encodedData;
