What are the potential drawbacks of manually creating JSON strings in PHP?
Manually creating JSON strings in PHP can be error-prone and time-consuming, as it requires proper formatting and escaping of special characters. To avoid these potential drawbacks, you can use the `json_encode` function provided by PHP, which automatically converts PHP data structures into JSON format.
$data = array(
    'name' => 'John Doe',
    'age' => 30,
    'email' => 'john.doe@example.com'
);
$jsonString = json_encode($data);
echo $jsonString;
