Array
(
    [0] => Array
        (
            [name] => Lorem
            [number] => 11
        )

    [1] => Array
        (
            [name] => ipsum
            [number] => 22
        )

)

As of PHP 8.0, you can set the length to 0 (or null, or omit it entirely) for the fgetcsv() function if you don't want to limit the maximum line length.
