Are there any specific PHP functions or methods that are recommended for working with JSON arrays?

When working with JSON arrays in PHP, the `json_encode()` function is commonly used to convert PHP arrays into a JSON string, while `json_decode()` is used to convert JSON strings back into PHP arrays. These functions are recommended for encoding and decoding JSON data in PHP.

// Example of encoding a PHP array into a JSON string
$data = ['name' => 'John', 'age' => 30];
$jsonString = json_encode($data);

// Example of decoding a JSON string into a PHP array
$jsonString = '{"name":"John","age":30}';
$data = json_decode($jsonString, true);
