Are there any best practices for handling CSV files in PHP?

When handling CSV files in PHP, it is important to follow best practices to ensure data integrity and security. One common best practice is to use the built-in functions like fgetcsv() to read CSV files line by line and parse the data correctly. Additionally, it is recommended to sanitize input data and validate the CSV file format to prevent any potential security vulnerabilities. 

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

// Read the CSV file line by line
while (($data = fgetcsv($csvFile)) !== false) {
    // Process the CSV data here
}

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