What are some best practices for handling CSV files in PHP, especially when preparing them for a Cronjob?

When handling CSV files in PHP, especially when preparing them for a Cronjob, it is important to properly read, manipulate, and write the data. Best practices include using functions like fgetcsv() to read CSV files, processing the data as needed, and using fputcsv() to write the modified data back to a new CSV file. It is also important to handle errors and exceptions gracefully to ensure the Cronjob runs smoothly. 

// Read the CSV file
$csvFile = 'data.csv';
$handle = fopen($csvFile, 'r');
if ($handle !== false) {
    while (($data = fgetcsv($handle)) !== false) {
        // Process the data as needed
    }
    fclose($handle);
} else {
    die('Error opening file.');

// Write the modified data to a new CSV file
$newCsvFile = 'new_data.csv';
$handle = fopen($newCsvFile, 'w');
if ($handle !== false) {
    // Write headers if needed
    // fputcsv($handle, ['Header1', 'Header2', 'Header3']);
    // Write the modified data
    // fputcsv($handle, $modifiedData);
    fclose($handle);
} else {
    die('Error opening file.');
}
