PHP Random Shuffle Array Maintaining Key => Value

Question

I\'ve been looking on google for the answer but can\'t seem to find something fool-proof and cant really afford to mess this up (going live into a production site).

Answer 1

  $testArray = array('a' => 'apple', 'b' => 'ball', 'c' => 'cat', 'd' => 'dog');
  $keys = array_keys($testArray); //Get the Keys of the array -> a, b, c, d
  shuffle($keys); //Shuffle The keys array -> d, a, c, b
  $shuffledArray = array();
  foreach($keys as $key) {
    $shuffledArray[$key] = $testArray[$key]; //Get the original array using keys from shuffled array
  }
  print_r($shuffledArray);
  /*
  Array
  (
      [d] => dog
      [a] => apple
      [c] => cat
      [b] => ball
  )
  */
