title: Implode an inner array values
body: <p>An array</p>
  
  <pre><code>Array
  (
      [0] =&gt; Array
      (
          [Detail] =&gt; Array
          (
              [detail_id] =&gt; 1
          )
  
      )
  
      [1] =&gt; Array
      (
          [Detail] =&gt; Array
          (
              [detail_id] =&gt; 4
          )
  
      )
  
  )
  </code></pre>
  
  <p>Is it possible to use implode function with above array, because I want to implode <code>detail_id</code>  to get <code>1,4</code>.</p>
  
  <p>I know it is possible by foreach and appending the array values,
      but want to know whether this is done by implode function or any other inbuilt function in PHP</p>
