I am pulling data from a multidimensional array. While using foreach loop, I am getting confused and can't pull out data from my array. Here is my array named as $result_array:

Array
(
    [0] => Array
        (
            [0] => Array
                (
                    [category_id] => 19
                    [category_name] => Food
                    [publication_status] => 1
                    [deletion_status] => 1
                )

            [1] => Array
                (
                    [category_id] => 16
                    [category_name] => Gourmet
                    [publication_status] => 1
                    [deletion_status] => 1
                )

            [2] => Array
                (
                    [category_id] => 17
                    [category_name] => Islamic Product
                    [publication_status] => 1
                    [deletion_status] => 1
                )


        )

    [1] => Array
        (
            [0] => Array
                (
                    [category_id] => 28
                    [category_name] => Dry Food
                    [publication_status] => 1
                    [deletion_status] => 1
                )

            [1] => Array
                (
                    [category_id] => 39
                    [category_name] => Testt
                    [publication_status] => 1
                    [deletion_status] => 1
                )

            [2] => Array
                (
                    [category_id] => 37
                    [category_name] => Seasonal Items
                    [publication_status] => 1
                    [deletion_status] => 1
                )

            [3] => Array
                (
                    [category_id] => 38
                    [category_name] => Icon Items
                    [publication_status] => 1
                    [deletion_status] => 1
                )

        )

    [2] => Array
        (
            [0] => Array
                (
                    [category_id] => 29
                    [category_name] => Biscuits
                    [publication_status] => 1
                    [deletion_status] => 1
                )

        )

    [3] => Array
        (
            [0] => Array
                (
                    [category_id] => 30
                    [category_name] => Nutty
                    [publication_status] => 1
                    [deletion_status] => 1
                )

        )

)

Here is my loop:

foreach($result_array as $info) {
    echo $info['category_name'].'<br>';
}

This loop is giving me an error saying undefined index category_name. I am newbie in this field. Can anyone enlighten me up? Thanks

  • Nope @Siraj . My array is different than that. Answer is already given. I had to use foreach 2 times Commented Dec 30, 2017 at 15:41

Reset to default

you need double foreach, like this:

foreach($result_array as $outer_array)
    foreach($outer_array as $inner_array)
        echo $inner_array['category_name'] . '<br>';

The $result_array you are looping over has 4 elements and none of them have value with key category_name. You need to do double foreach or something wiser there.
