title: array does not echo correc value
body: <p>I just initialize an array <code>$exp_arr</code> with some values. The <code>print_r($exp_arr[0])</code> results the following values</p>
  
  <pre><code>Array
  (
    [0] =&gt; Array
      (
          [id] =&gt; 40
          [email] =&gt; shishir012010@gmail.com
          [company_name] =&gt; Yahoo
          [title] =&gt; Developer2
          [location] =&gt; Noida
          [description] =&gt; 
          [smonth] =&gt; January
          [syear] =&gt; 2012
          [emonth] =&gt; December
          [eyear] =&gt; 2015
          [status] =&gt; 0
      )
  
  )
  </code></pre>
  
  <p>After that <code>echo $exp_arr[0]['location']</code> does not print anything.</p>
  
  <p>I also tried <code>var_dump($exp_arr[0]['location'])</code> and it results in output of <code>NULL</code>.</p>
  
  <p>I can't track the problem. I have put the echo statement just after the print_r statement just like that</p>
  
  <pre><code>echo "&lt;pre&gt;";
  print_r($exp_arr[0]);
  echo $exp_arr[0]['location'];
  var_dump($exp_arr[0]['location']); 
  </code></pre>
