<?php

$list = array (
    array('aaa', 'bbb', 'ccc', 'dddd'),
    array('123', '456', '789'),
    array('"aaa"', '"bbb"')
);

$file = new SplFileObject('file.csv', 'w');

foreach ($list as $fields) {
    $file->fputcsv($fields);
}

?>

The above example will write the following to file.csv:

aaa,bbb,ccc,dddd
123,456,789
