What potential issues can arise when generating and handling CSV files in PHP?

One potential issue when generating and handling CSV files in PHP is the presence of special characters like commas or double quotes within the data, which can break the CSV structure. To solve this problem, you can wrap each field in double quotes and escape any existing double quotes within the data. 

// Generate and handle CSV file while handling special characters
$csvData = [
    ['John Doe', '25,000', 'New York, NY'],
    ['Jane Smith', '30,000', 'Los Angeles, CA'],
];

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

foreach ($csvData as $fields) {
    fputcsv($fp, $fields);
}

fclose($fp);
