title: Adding an item to an associative array
body: <pre class="lang-php prettyprint-override"><code>//go through each question
  foreach($file_data as $value) {
     //separate the string by pipes and place in variables
     list($category, $question) = explode('|', $value);
  
     //place in assoc array
     $data = array($category =&gt; $question);
     print_r($data);
  
  }
  </code></pre>
  <p>This is not working as it replaces the value of data. How can I have it add an associative value each loop though? <code>$file_data</code> is an array of data that has a dynamic size.</p>
