What potential issues can arise when using JavaScript to sort and display data retrieved from a PHP script?

One potential issue that can arise when using JavaScript to sort and display data retrieved from a PHP script is that the data may not be in the correct format for sorting. To solve this issue, you can ensure that the PHP script returns the data in a structured format, such as JSON, that can easily be manipulated by JavaScript for sorting and displaying.

// PHP script to retrieve and return data in JSON format
$data = array(
    array("name" => "John", "age" => 30),
    array("name" => "Jane", "age" => 25),
    array("name" => "Bob", "age" => 35)
);

header('Content-Type: application/json');
echo json_encode($data);
