php打乱数组二维数组多维数组的简单实例

<?php function shuffle_assoc($list) {  if (!is_array($list)) return $list;  $keys = array_keys($list);  shuffle($keys);  $random = array();  foreach ($keys as $key)   $random[$key] = $list[$key];  return $random; } ?>

<?php function shuffle_assoc($list) { if (!is_array($list)) return $list; $keys = array_keys($list); shuffle($keys); $random = array(); foreach ($keys as $key) $random[$key] = shuffle_assoc($list[$key]); return $random; } ?>

/*** Shuffles an associative array recursive* * @param array $array* @return array**/function rec_assoc_shuffle($array){ $ary_keys = array_keys($array); $ary_values = array_values($array); shuffle($ary_values); foreach($ary_keys as $key => $value) {  if (is_array($ary_values[$key]) AND $ary_values[$key] != NULL) {   $ary_values[$key] = rec_assoc_shuffle($ary_values[$key]);  }  $new[$value] = $ary_values[$key]; } return $new;}
