What are the best practices for processing CSV files in PHP to ensure accurate data extraction?

When processing CSV files in PHP, it is important to handle data extraction carefully to ensure accurate results. One best practice is to use the built-in functions like fgetcsv() to read the CSV file line by line and parse the data correctly. Additionally, always sanitize and validate the extracted data to prevent any potential security vulnerabilities or data inconsistencies. 

// Open the CSV file for reading
$csvFile = fopen('data.csv', 'r');

// Loop through each line of the CSV file
while (($data = fgetcsv($csvFile)) !== false) {
    // Process the extracted data here
    // Remember to sanitize and validate the data
}

// Close the CSV file
fclose($csvFile);
