What are some best practices for encoding and decoding binary data in PHP?

When encoding and decoding binary data in PHP, it is important to use functions that handle binary data properly to prevent data corruption or loss. One common approach is to use base64 encoding and decoding functions, such as base64_encode() and base64_decode(), to safely convert binary data to a string representation and back. 

// Encoding binary data to base64
$binaryData = file_get_contents('example.jpg');
$encodedData = base64_encode($binaryData);

// Decoding base64 data back to binary
$decodedData = base64_decode($encodedData);

// Checking if the decoding was successful
if ($decodedData !== false) {
    // Process the decoded binary data
    file_put_contents('decoded_example.jpg', $decodedData);
} else {
    // Handle decoding error
    echo 'Error decoding data';
}
