accessing array by key returns null, while dumping looks good

I have an array, parsed from a yaml string, which behaves weird. This code produces the following output:

var_dump($params['layout']);

var_dump($params);

foreach($params as $key => $value) {
    echo $key . ': ' . $value . '<br>';
}

Output:

NULL

array(4) {
  ["layout"]=>
  string(4) "home"
  ["title"]=>
  string(4) "home"
  ["date"]=>
  string(10) "2017-03-21"
  ["description"]=>
  string(55) "Everything is alive and other tales from the thresholds"
}

layout: home
title: home
date: 2017-03-21
description: Everything is alive and other tales from the thresholds

Why does accessing the first item by key return null?

try var_dump($params["layout"]); once – Exprator May 29 '17 at 15:37

In your array "layout" is really `"layout"` It's ByteOrderMark https://en.wikipedia.org/wiki/Byte_order_mark – splash58 May 29 '17 at 15:39
you need to remove space in `layout` key – Omi May 29 '17 at 15:49
Thank you splash58, didn't think of that. – thgie May 30 '17 at 06:21
