贴一段代码,在php中获取随机数组 不用多说,直接贴代码,php中的array_rand很变态,突破了正常人的理解,繁琐

function create_random_ids( $min,$max,$limited )
{
  $_base_ids = range($min,$max);
  $_temp_key = array_rand ($_base_ids,min(count($_base_ids),$limited+10));
  //拼接
  $ids = array();
  for ($x=0; $x < count($_temp_key); $x++) {
    $ids[] = $_base_ids[$_temp_key[$x]];
  }
  return $ids;
}
