How can valid JSON data be ensured when using chrome://restclient for testing PHP scripts?

To ensure valid JSON data when using chrome://restclient for testing PHP scripts, you can use the json_encode function in PHP to encode your data before sending it back to the client. This will ensure that the response is in valid JSON format.

// Sample PHP script to return JSON data
$data = array(
    'name' => 'John Doe',
    'age' => 30,
    'city' => 'New York'
);

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