title: Output (echo/print) everything from a PHP Array
body: <p>Is it possible to echo or print the entire contents of an array without specifying which part of the array?</p>
  
  <p>The scenario: I am trying to echo everything from:</p>
  
  <pre><code>while($row = mysql_fetch_array($result)){
  echo $row['id'];
  }
  </code></pre>
  
  <p>Without specifying "id" and instead outputting the complete contents of the array.</p>
