如何获取fetchAll的数字项？

Here is the result of my code:

$res = $stm->fetchAll();
/*
Array
(
    [0] => Array
        (
            [name] => apple
            [0] => apple
            [colour] => red
            [1] => red
        )

    [1] => Array
        (
            [name] => pear
            [0] => pear
            [colour] => green
            [1] => green
        )
)

And if I use fetchAll(PDO::FETCH_ASSOC), the result will be:

/*
Array
(
    [0] => Array
        (
            [name] => apple
            [colour] => red
        )

    [1] => Array
        (
            [name] => pear
            [colour] => green
        )
)

Now I want to know, how can I get this ?

/*
Array
(
    [0] => Array
        (
            [0] => apple
            [1] => red
        )

    [1] => Array
        (
            [0] => pear
            [1] => green
        )
)

Noted that PDO::FETCH_COLUMN won't return the expected result.

Use PDO::FETCH_NUM

$result = $sth->fetchAll(PDO::FETCH_NUM);

try this
