What is the best way to display CSV values in a single line using PHP?

To display CSV values in a single line using PHP, you can read the CSV file, parse the values, and then concatenate them into a single string separated by commas. This can be achieved by using the fgetcsv() function to read each row of the CSV file and implode() function to combine the values into a single line.

$file = fopen('data.csv', 'r');
if ($file) {
    while (($data = fgetcsv($file)) !== false) {
        echo implode(',', $data);
    }
    fclose($file);
}
