What are the potential pitfalls of reading, writing, and updating CSV files in PHP?

One potential pitfall of reading, writing, and updating CSV files in PHP is the risk of encountering issues with data formatting, such as incorrect delimiters or escaping characters. To avoid this, it is important to use PHP functions specifically designed for handling CSV files, such as fgetcsv() and fputcsv(), which automatically handle these formatting concerns. 

// Read a CSV file using fgetcsv()
$file = fopen('data.csv', 'r');
while (($row = fgetcsv($file)) !== false) {
    // Process each row
}
fclose($file);

// Write to a CSV file using fputcsv()
$file = fopen('data.csv', 'w');
$data = ['John Doe', 'johndoe@example.com'];
fputcsv($file, $data);
fclose($file);
