title: Interpolation of arrays in php
body: <p>A simple question for pros.
   There is a code with which we are getting access to an array value:</p>
  
  <pre><code>foreach($basket as $k=&gt;$v)
   echo  "{$v[0]['title']} &lt;br&gt;";
  
  
  
  it prints to browser:
   book 1
   book 2
   etc...
  </code></pre>
  
  <p>and now, if we delete the braces such as this:</p>
  
  <pre><code>echo  "$v[0]['title'] &lt;br&gt;";
  </code></pre>
  
  <p>it prints:</p>
  
  <pre><code>array['title']
  array['title']
  etc...
  </code></pre>
  
  <p>so interpreter "sees" <code>$v[0]</code> and this is an array yes. but he can't get access to <code>['title']</code>.</p>
  
  <p>plz tell newbie, why does it happen? i know that braces interpolate a variables in cases when there are some letters around. But there are no letters around here.</p>
