PHP - Access array in array

Question

I am working with response from Youtube Data API and I don't know how to read each values in the array.

Array
(
[0] => youtube#channelListResponse
[1] => "X"
   [2] => Array (
                 [totalResults] => 1
                 [resultsPerPage] => 1
                )
[3] => Array (
    [0] => Array
        (
          [kind] => youtube#channel
          [etag] => "XX"
          [id] => XXX
            )
        )
)

When I try to access [id] with echo $array[3]['id'] it returns Notice: Undefined offset: 3

You mean how to access single values or loop through each value? — Rizier123, Feb 19 '16 at 11:59
To access `totalResults` for an example, you would do: `echo $arrayname[2]['totalResults']`. — Max, Feb 19 '16 at 12:00
@khalnas Are you certain your array looks like this? Could you give us the exact output from `print_r` (without ruining the formatting)? — h2ooooooo, Feb 19 '16 at 12:42
`Array ( [kind] => youtube#channelListResponse [etag] => "X" [pageInfo] => Array ( [totalResults] => 1 [resultsPerPage] => 1 ) [items] => Array ( [0] => Array ( [kind] => youtube#channel [etag] => "XX" [id] => X ) ) )` — khalnas, Feb 19 '16 at 12:48

AS Max said you can access single value in array in array by

$arrayName[index]['key']

Example You can access 'kind' with

$arrayName[3]['kind']

Since, inner level array is key value paired you need to specify key instead of index. If you want to access all value, you can do it with foreach loop and check type of each value use'gettype()' method. if type is array then use same function recursively.
