What are some common errors or misunderstandings that can occur when exporting data to CSV files using fputcsv in PHP?

One common error when exporting data to CSV files using fputcsv in PHP is not properly handling special characters, such as commas or double quotes, within the data. To avoid this issue, you can use the PHP function `str_replace` to escape these characters before writing the data to the CSV file. 

// Example code snippet to properly handle special characters when exporting data to CSV using fputcsv

$fp = fopen('data.csv', 'w');

$data = array(
    'John Doe, Jr.',
    'Jane "Doe" Smith',
    '123, Main Street'
);

foreach ($data as $row) {
    fputcsv($fp, array_map(function($value) {
        return str_replace(',', '\,', str_replace('"', '\"', $value));
    }, $row));
}

fclose($fp);
