title: How to Access Different Keys and Values in a PHP Array
body: <p>I have this PHP array: </p>
  
  <pre><code>Array
  (
      [Album Title 1] =&gt; Array
          (
              [Track Title 1] =&gt; 27
              [Track Title 2] =&gt; 18
              [Track Title 3] =&gt; 7
          )
  
      [Album Title 2] =&gt; Array
          (
              [Track Title 1] =&gt; 41
              [Track Title 2] =&gt; 17
              [Track Title 3] =&gt; 12
          )
  
  )
  </code></pre>
  
  <p>How can I echo "Album Title 1", "Track Title 1", and it's corresponding int(27), without using dot notation? (I don't know the exact title of "Album Title 1")</p>
  
  <p>To get "Album Title 1", I've tried:</p>
  
  <pre><code>echo $albums[0];
  
  print_r(array_values($albums));
  
  foreach ($albums as $a){
      print_r($a) . "\n";
  }
  </code></pre>
  
  <p>etc... </p>
  
  <p>I've tried more variations of these for every value I need. </p>
