How can JSON be used as an alternative format for storing and retrieving arrays in PHP files?
When storing and retrieving arrays in PHP files, using JSON as an alternative format can provide a more efficient and structured way to handle data. JSON allows for easy serialization and deserialization of arrays, making it simpler to store and retrieve complex data structures. To use JSON for storing and retrieving arrays in PHP files, you can utilize the json_encode() function to convert an array into a JSON string for storage, and json_decode() function to convert a JSON string back into an array for retrieval.
// Storing an array in a PHP file using JSON
$data = array("name" => "John", "age" => 30, "city" => "New York");
$jsonData = json_encode($data);
file_put_contents('data.json', $jsonData);
// Retrieving an array from a PHP file using JSON
$jsonData = file_get_contents('data.json');
$data = json_decode($jsonData, true);
print_r($data);
