PHP查找数值数组中不重复最大和最小的10个数的方法分享

  //随机生成1万个元素的数组  for($i=0;$i<10000;$i++){   $ary[]=rand(1,100000);  }  $ary=array_unique($ary); //去重复数值  sort($ary);//顺序排序  $min_10=array_slice($ary,0, 10);//取出最小的10个数值  $max_10=array_slice($ary,-10, 10);//取出最大的10个数值  rsort($max_10);//倒序排序最大的10个数值  echo '
';  print_r($min_10);  print_r($max_10);  unset($ary,$min_10,$max_10);

  Array  (    [0] => 16    [1] => 19    [2] => 22    [3] => 31    [4] => 40    [5] => 49    [6] => 71    [7] => 74    [8] => 80    [9] => 92  )  Array  (    [0] => 99997    [1] => 99991    [2] => 99973    [3] => 99958    [4] => 99955    [5] => 99946    [6] => 99939    [7] => 99933    [8] => 99927    [9] => 99900  )
