How can the code be optimized to ensure that the exported result does not appear as a list in the CSV file?

The issue can be resolved by using the `implode()` function to concatenate the array values into a single string before writing it to the CSV file. This will ensure that the exported result does not appear as a list in the CSV file. 

<?php

$data = array(
    array('John', 'Doe', 30),
    array('Jane', 'Smith', 25),
    array('Tom', 'Brown', 35)
);

$fp = fopen('export.csv', 'w');

foreach ($data as $row) {
    fputcsv($fp, $row);
}

fclose($fp);
