When working with CSV files in PHP, what are the potential pitfalls to avoid, especially in terms of data manipulation and retrieval?

One potential pitfall when working with CSV files in PHP is not properly handling data manipulation and retrieval, which can lead to errors or incorrect data being processed. To avoid this, it's important to sanitize user input, validate data before manipulation, and handle errors gracefully to prevent data corruption. 

// Example of sanitizing user input before processing CSV data
$userInput = $_POST['user_input'];
$sanitizedInput = filter_var($userInput, FILTER_SANITIZE_STRING);

// Example of validating data before manipulation
if (empty($sanitizedInput)) {
    // Handle error or display message to user
} else {
    // Process CSV data using sanitized input
}

// Example of handling errors gracefully
try {
    // Code for CSV data manipulation and retrieval
} catch (Exception $e) {
    echo "An error occurred: " . $e->getMessage();
}
