What are some potential pitfalls to be aware of when working with CSV files in PHP?

One potential pitfall when working with CSV files in PHP is not handling the data properly, which can lead to errors or unexpected behavior. To avoid this, it's important to properly parse the CSV data and handle any special characters or formatting issues that may arise. 

// Example of properly parsing CSV data in PHP
$csvFile = 'data.csv';
$handle = fopen($csvFile, 'r');

if ($handle !== false) {
    while (($data = fgetcsv($handle, 1000, ',')) !== false) {
        // Process each row of data here
        print_r($data);
    }

    fclose($handle);
} else {
    echo 'Error opening file.';
}
