What are the best practices for transferring data between PHP and JavaScript for table loading?

When transferring data between PHP and JavaScript for table loading, the best practice is to use JSON format for data interchange. PHP can encode data into JSON format using the `json_encode()` function, and JavaScript can parse JSON data using `JSON.parse()`. This ensures a standardized format for data transfer and simplifies the process of handling data on both the server and client sides.

// PHP code to encode data into JSON format
$data = array(
    array('id' => 1, 'name' => 'John Doe', 'age' => 30),
    array('id' => 2, 'name' => 'Jane Smith', 'age' => 25)
);

$jsonData = json_encode($data);
echo $jsonData;
