PHP-将数组数据回显到form_input

Question

How to echo an array to a form?

My array

Array
(
    [0] => Array
        (
            [id] => item1
            [price] => 300
            [quantity] => 1
        )
    [1] => Array
        (
            [id] => item2
            [price] => 400
            [quantity] => 2
        )
)

I tried like (codeigniter):

echo form_textarea('detail_prod',print_r($detail));

And I got like

what happen? why the result is 1 ?

It's possible to echo to a form in array format?
