What are some recommended libraries or tools for working with CSV files in PHP to improve efficiency and code quality?

Working with CSV files in PHP can be a common task, but it can also be error-prone and inefficient if not handled properly. To improve efficiency and code quality, it is recommended to use libraries or tools specifically designed for working with CSV files in PHP. These libraries can provide functions for reading, writing, and manipulating CSV data, as well as handling edge cases like escaping special characters and handling large files.

// Example using the League CSV library to read a CSV file
require 'vendor/autoload.php';

use League\Csv\Reader;

$csv = Reader::createFromPath('data.csv', 'r');
$csv->setHeaderOffset(0);

foreach ($csv as $record) {
    // Process each row of the CSV file
    var_dump($record);
}
