What are some best practices for improving the readability and efficiency of PHP code when processing CSV files?

When processing CSV files in PHP, it is important to write clean and efficient code to improve readability and performance. One best practice is to use built-in functions like fgetcsv() to read the file line by line and parse the data. Additionally, consider using arrays to store and manipulate the CSV data for easier access and manipulation. 

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

// Read and process each line of the CSV file
while (($data = fgetcsv($file)) !== false) {
    // Process the CSV data here
    // Example: echo the first column of each row
    echo $data[0] . PHP_EOL;
}

// Close the file
fclose($file);
