title: How can I assign an array to another variable in php?
body: <p>I have defined an array in php</p>
  
  <pre><code>    $letters = array("A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","W","V","X","Y","Z");
  </code></pre>
  
  <p>Then I try to assign the array to a new variable, that is also an array:</p>
  
  <pre><code>   $new_array = array();
     $new_array =  $letters;
  </code></pre>
  
  <p>But it's not working, why?</p>
