Trying to access object element within an array

Question

I'm using a framework at work that I'm slightly unfamiliar with and trying to access elements of an object that are stored within an array called $items. I've tried die(print_r($items[0])) to try to get the first element but it says 0 is an undefined index. Here is the result of print_r($items):

Any help is much appreciated. If you have any questions I'll gladly answer because I know this is a bit vague. I think it would take up way too much space to explain how this framework actually works.

I figured out that the first element is 2 and not 0, but I'm still unable to access any of the elements within the object. When I tried print_r($items[2]->fields) it didn't return anything, just a blank page.

from the code it's like the key/index start at [2]. there was no zero — codingbiz

I think this is what you want:

$item = current($items);
foreach ($item->fields as $key => $val) {
  echo "$key => $val\n";
}

Update:

It seems like you cannot get $item->fields since it is a protected property of Dase_DBO_Project object:

[fields:protected] => Array

I don't see any element with index 0 in your array, only keys 5, 4, 3 and 2. To get the first item from array use current($items) or reset($items).

Your array listed here does not have an index of 0 (For more help look here: http://php.net/manual/en/language.types.array.php) Rather than attempting to access each item with the index. Why don't you use a foreach?

foreach($items as $item)
{
  //Do what you want with each object here
  var_dump($item);
}

This will allow you to access each object without using the index. For more information using foreach take a look here: https://www.php.net/manual/en/control-structures.foreach.php

Cheers!

Yeah I was going to use that on another page, right now I'm just trying to pull a single element from the object within the array.
