Echo out from a multidimensional array - php

Question

I have this array:
Array
(
[result] => Array
(
[lastModified] => 1465097340000
[name] => Ulminia
[realm] => Zangarmarsh
[battlegroup] => Rampage
[class] => 3
[race] => 4
[gender] => 1
[level] => 100
[achievementPoints] => 14915
[thumbnail] => hellscream/74/113337162-avatar.jpg
[calcClass] => Y
[faction] => 0
[items] => Array
(
[averageItemLevel] => 710
[averageItemLevelEquipped] => 709
[head] => Array
(
[id] => 125899
[name] => Warmongering Gladiator's Helm
[icon] => inv_helm_mail_raidhunter_p_01
[quality] => 4
[itemLevel] => 710
[tooltipParams] => Array
(
[transmogItem] => 71356
[timewalkerLevel] => 100
)
I want to echo out from the [head] array the [id] and the [quality]. If i just echo out the [id] everything works, but if i want to echo out the [quality] too, it doesn´t work.
My code:
$items = $r['result']['items'];
echo 'Head: '.$items['head']['id']['quality']."\n";
foreach($items['head']['tooltipParams'] as $key => $value){
echo 'head_'.$key.': '.$value.'\n';
}

Answer 1

echo $items['head']['id']['quality'];
The above statement means you are printing out the subkey "quality" of key "id", which doesn't exist.
You need to concatenate both key values as follows:
echo $items['head']['id'] . ' ' . $items['head']['quality'];
... or
echo $items['head']['id'], ' ', $items['head']['quality'];

Answer 2

$items['head']['id']['quality']."\n"; is trying to read the element with the key quality inside the array stored inside id. However, id is not an array, which is why this fails.
In order to read two fields, you need to read them seperately:
echo 'Head: ID=' . $items['head']['id'] . ', quality = ' . $items['head']['quality'] . "\n";

Answer 3

Notice that the id and the quality are in the same array.
//ID
echo $items['head']['id'];
//Quality
echo $items['head']['quality'];
