Are there any recommended PHP libraries or tools for handling CSV formatting and export in a secure manner?

Handling CSV formatting and export in a secure manner involves ensuring that the data being exported is properly sanitized to prevent any potential security vulnerabilities such as SQL injection or XSS attacks. One recommended approach is to use PHP libraries like League\Csv or PHPExcel, which provide secure methods for handling CSV data and exporting it in a safe manner. 

// Example using League\Csv library for handling CSV export securely

use League\Csv\Writer;

// Create a new CSV writer instance
$csv = Writer::createFromString('');

// Add headers to the CSV file
$csv->insertOne(['Column 1', 'Column 2', 'Column 3']);

// Add data rows to the CSV file
$csv->insertOne(['Data 1', 'Data 2', 'Data 3']);

// Output the CSV file to the browser for download
header('Content-Type: text/csv');
header('Content-Disposition: attachment; filename="export.csv"');
echo $csv->getContent();
