How can PHP developers ensure compatibility with other programming languages, such as Objective-C, when working with JSON data structures?

PHP developers can ensure compatibility with other programming languages, such as Objective-C, when working with JSON data structures by following the JSON standard for data interchange. This includes properly encoding and decoding JSON data in PHP using built-in functions like json_encode() and json_decode(). By adhering to the JSON standard, developers can ensure that the data exchanged between PHP and other languages is formatted correctly and can be easily parsed on both ends. 

// Encode data to JSON format
$data = array('name' => 'John', 'age' => 30);
$json_data = json_encode($data);

// Decode JSON data from Objective-C
$received_json_data = '{"name": "Jane", "age": 25}';
$decoded_data = json_decode($received_json_data, true);

// Access decoded data
echo $decoded_data['name']; // Output: Jane
echo $decoded_data['age']; // Output: 25
