What potential pitfalls should be considered when manipulating CSV data in PHP, as seen in the provided code snippets?

One potential pitfall when manipulating CSV data in PHP is not properly handling errors or exceptions that may occur during the process. To prevent unexpected behavior or data corruption, it is important to implement error handling mechanisms such as try-catch blocks to catch and handle any potential issues that may arise. 

try {
    // Code for manipulating CSV data goes here
} catch (Exception $e) {
    // Handle the exception, log the error, or display a user-friendly message
    echo "An error occurred: " . $e->getMessage();
}
