How to find the largest and smallest 10 numbers in a numerical array in PHP

This article mainly introduces the method of PHP to find the largest and smallest 10 numbers in a numerical array, involving the usage skills of array_unique and array_slice methods in PHP. It is of great practical value. Friends who need it can refer to it

The example of this article describes the method of PHP to find the 10 largest and smallest numbers in a numerical array that do not repeat. Share it with everyone for your reference. The details are as follows:

1. The php code is as follows:

//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($max_10);//倒序排序最大的10个数值
echo &#39;<pre class="brush:php;toolbar:false">&#39;;
print_r($min_10);
print_r($max_10);
unset($ary,$min_10,$max_10);

2. The running result is as follows:

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
)
