Are there any potential pitfalls or best practices to consider when working with JSON data in PHP?

One potential pitfall when working with JSON data in PHP is not properly handling errors that may occur during encoding or decoding. It's important to check for errors and handle them appropriately to prevent unexpected behavior in your application. One best practice is to use the json_last_error() function to retrieve the last JSON error that occurred and handle it accordingly in your code. 

// Example of handling JSON encoding error
$data = ['name' => 'John', 'age' => 30];
$json = json_encode($data);

if ($json === false) {
    $error = json_last_error_msg();
    // Handle the error, log it, or display a user-friendly message
}

// Example of handling JSON decoding error
$json = '{"name": "John", "age": 30}';
$data = json_decode($json);

if ($data === null && json_last_error() !== JSON_ERROR_NONE) {
    $error = json_last_error_msg();
    // Handle the error, log it, or display a user-friendly message
}
