php Multidimensional Array - Undefined offset / index

Question

I have an array that holds a number of arrays. I access them in turn e.g.

print_r($orderData[0]) and the output is:

Array (
  [201] => Array (
    [name] => SuperMarket One
    [type] => line_item
    [item_meta] => Array (
      [_qty] => Array (
        [0] => 1
      )
    )
  )
)

My issue is, I can't seem to access anything e.g. print_r($orderData[0]['name']) gives me:

Notice: Undefined index: name in /Path

Likewise, I can't use print_r($orderData[0][0]) etc.

I must be missing something quite obvious here.

You can access like this: $orderData[0][201]['name'] – MoeinPorkamel Sep 10 '16 at 15:16 — MoeinPorkamel, Sep 10 '16 at 15:16

You have another array in it with the key 201. Use PHP's function var_dump($orderData[0]) to view the complete structure of your array.

Can you explain why the 201 is there? And not: $orderData[0][0]['name']? – Colin Sep 10 '16 at 19:45
201 is the first inner index of your array. So you can access it using that index. – SanketR Sep 11 '16 at 05:41
