title: Loop into a multidimensional array in PHP
body: <p>I have this array in PHP:</p>
  
  <pre><code>array( 
      "name" =&gt; "Cherry", 
      "desc" =&gt; "I'm a cherry.",
      "keys" =&gt; array(
              "Africa",
              "India",
              "America"
      ),
      "pict" =&gt; "image1.png",
  )
  </code></pre>
  
  <p>And I want to loop into this and between <code>keys</code> to display to countries/continents.</p>
  
  <p>This is what I have already tried:</p>
  
  <pre><code>foreach($details as $detail) {
      foreach($keys as $key) {
          echo $key;
      }
  }
  </code></pre>
