In what ways can the efficiency and readability of PHP code for Java integration be improved, particularly in handling result outputs?

To improve the efficiency and readability of PHP code for Java integration, particularly in handling result outputs, you can use JSON encoding to convert Java objects into a format that PHP can easily work with. This allows for a more structured and standardized way of passing data between the two languages, making the code cleaner and easier to understand.

// Java code to convert Java object to JSON string
Gson gson = new Gson();
String json = gson.toJson(javaObject);

// PHP code to decode JSON string and handle result output
$result = json_decode($json, true);
if ($result) {
    // Process the result data here
} else {
    // Handle any errors or unexpected data
}
