What is the correct usage of base64_encode() and base64_decode() in PHP for encoding and decoding data?

When using base64_encode() in PHP, you encode a string into base64 format, which is useful for encoding binary data such as images or files for transmission over text-based protocols. To decode this base64-encoded data back into its original form, you can use base64_decode(). Make sure to use these functions correctly to ensure proper encoding and decoding of data. 

// Encoding data using base64_encode()
$data = 'Hello, World!';
$encoded_data = base64_encode($data);

// Decoding data using base64_decode()
$decoded_data = base64_decode($encoded_data);

echo "Encoded data: " . $encoded_data . "\n";
echo "Decoded data: " . $decoded_data;
