php multidimension array

I'm trying to retrieve information from one array. I'm getting an Array to String error when I try to access the information inside "topics". On one page I am listing out the topics with .implode. What function do I need to use to access each topic? Then access the individual topic information on another page. 

$tracks[] = [
  "topics" => [
    "Physiology" => [
      "media" => [
        "image file name"
      ],
      "paragraphs" => [
        "text"
      ],
    "SA Node and Pacemakers",
    "Atrial Depolarization",
    "Atrio Ventricular Conduction",
    "Ventricular Depolarization",
    "Repolarization",
    "Events at the Cellular Level",
    "Electrodes",
    "ECG Leads and Placement",
  ],

Hi Ryan,

I have updated your code formatting which you can learn more about at Posting Code to the Forum.

Is this all of your code? It seems to be missing the key part where you're calling your array values.

This should work, or if it doesn't at least we have better formatting. Basically what happens is your array items such as "SA Node and Pacemakers" etc.. should be within topics array, they are currently in tracks array

$tracks = [
    'topics' => [
       'Psychology' => [
         'media' => [
           'image file name'
         ],
         'paragraphs' => [
           'text',
         ],
       ],
       "SA Node and Pacemakers",
       "Atrial Depolarization",
       "Atrio Ventricular Conduction",
       "Ventricular Depolarization",
       "Repolarization",
       "Events at the Cellular Level",
       "Electrodes",
       "ECG Leads and Placement",
    ],
  ];
