php - Adding an item to an associative array

Question

//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 => $question);
   print_r($data);

}

This is not working as it replaces the value of data. How can I have it add an associative value each loop though? $file_data is an array of data that has a dynamic size.

Answer 1

You can simply do this

$data += array($category => $question);

If your're running on php 5.4+

$data += [$category => $question];
