What is the role of json_encode in PHP and how does it handle special characters?

json_encode in PHP is used to convert a PHP array or object into a JSON string. When dealing with special characters, json_encode automatically escapes them to ensure they are properly encoded in the JSON output. This ensures that the JSON string is valid and can be safely transmitted or stored. 

$data = array(
    'name' => 'John Doe',
    'description' => 'Special characters like " and \ are properly handled by json_encode.'
);

$json_string = json_encode($data);

echo $json_string;
