title: Echoing several variable in random order
body: <p>I'm making simple test script with PHP+mysql.<br>
  The script gives the question and SELECT with 4 options (answers).<br>
  1 of them is correct, 3 others are incorrect, retrieved from mysql table.<br>
  I have 4 variables and all works fine, but I need to retrieve these variables in random order.<br></p>
  
  <pre><code>$variable1='1';
  $variable2='2';
  $variable3='3';
  $variable4='4';
  </code></pre>
  
  <p>Just need some direction what to learn, what method to use.<br>
  Many thanks in advance</p>
