How can PHP developers ensure that special characters are properly encoded and decoded when working with JSON strings?

Special characters in JSON strings need to be properly encoded and decoded to avoid issues with data integrity. PHP developers can use the `json_encode()` function to encode special characters before sending JSON data, and the `json_decode()` function to decode JSON data back into PHP objects. Additionally, using the `JSON_UNESCAPED_UNICODE` flag can help preserve Unicode characters during encoding. 

// Encoding special characters in a PHP array before converting to JSON
$data = array("name" => "John Döe");
$json = json_encode($data, JSON_UNESCAPED_UNICODE);

// Decoding JSON data back into a PHP object
$decodedData = json_decode($json);
