What tools or methods can be used to streamline the CSV import process in PHP?

When importing CSV files in PHP, it can be helpful to use libraries or functions that streamline the process. One popular tool for handling CSV imports in PHP is the `fgetcsv()` function, which reads a line from a CSV file and parses it into an array. Additionally, libraries like `league/csv` can simplify the import process by providing convenient methods for working with CSV data.

// Example using fgetcsv() function to import CSV file
$filename = 'data.csv';
$handle = fopen($filename, 'r');
if ($handle !== FALSE) {
    while (($data = fgetcsv($handle)) !== FALSE) {
        // Process each row of CSV data
        print_r($data);
    }
    fclose($handle);
}
