What are the potential pitfalls of using newline characters in text files for storing user data in PHP?

Using newline characters in text files for storing user data in PHP can lead to issues with parsing and reading the data correctly, especially if the newline character is used as a delimiter. To avoid potential pitfalls, it is recommended to use a different delimiter or format the data in a structured way, such as JSON or CSV. 

// Example of storing user data in a text file using JSON format
$userData = array(
    'username' => 'john_doe',
    'email' => 'john.doe@example.com',
    'age' => 30
);

// Encode the user data as JSON
$jsonUserData = json_encode($userData);

// Write the JSON data to a text file
file_put_contents('user_data.txt', $jsonUserData);
