Is it necessary to prepend each cell field with a single quote to prevent CSV injection, or are there alternative methods?

To prevent CSV injection, it is not necessary to prepend each cell field with a single quote. One alternative method is to properly sanitize and escape the data before writing it to the CSV file. This can be done using functions like `fputcsv()` in PHP, which automatically handles escaping special characters. 

// Sample data to be written to CSV
$data = array(
    array('John Doe', '25', 'john.doe@example.com'),
    array('Jane Smith', '30', 'jane.smith@example.com'),
);

// Open the file for writing
$fp = fopen('data.csv', 'w');

// Write data to CSV using fputcsv
foreach ($data as $fields) {
    fputcsv($fp, $fields);
}

// Close the file
fclose($fp);
