title: Declaring a variable as a string and later using it as an array?
body: <p>Did something change in the PHP where declaring a variable as a string and later using it as an array is not OK. We upgraded to bitnamies wamp stack and it broke our app. One of the variables</p>
  <p><code>$change=&quot;&quot;;</code></p>
  <p>Then later used</p>
  <p><code>$change[$k] = &quot;this&quot;;</code></p>
  <p>It remains a single string instead of turning into an array. Is this a php.ini config I can change?</p>
