How can JSON data be properly encoded and decoded in PHP for efficient data transfer?

To properly encode and decode JSON data in PHP for efficient data transfer, you can use the built-in functions json_encode() and json_decode(). When encoding data to JSON format, make sure to use json_encode() to convert PHP data structures into a JSON string. When decoding JSON data back into PHP, use json_decode() to convert the JSON string back into a PHP data structure. 

// Encoding data to JSON format
$data = array("name" => "John", "age" => 30, "city" => "New York");
$jsonData = json_encode($data);

// Decoding JSON data back into PHP
$decodedData = json_decode($jsonData, true);

// Accessing the decoded data
echo $decodedData['name']; // Output: John
echo $decodedData['age']; // Output: 30
echo $decodedData['city']; // Output: New York
