Answer: Use the PHP shuffle() function

You can use the PHP shuffle() function to randomly shuffle the order of the elements or values in an array. The shuffle() function returns FALSE on failure.

  • <?php
  • // Creating an array containing a range of elements
  • $numbers = range(1, 10);
  •

  • foreach ($numbers as $value){
  •     echo "$value" . "<br>";
  • }
  • ?>
