PHP Find a method for 10 digits without repeating the maximum and minimum in a numeric array _php tips

This example describes a method for PHP to find the maximum and minimum number of 10 digits in a numeric array. Share to everyone for your reference. Specifically as follows:

1. PHP code is as follows:

An array of randomly generated 10,000 elements for
($i =0 $i <10000; $i + +) {
 $ary []=rand (1,100000);
}
$ary =array_unique ($ary); Go to repeat
the value sort ($ary),//order sort
$min _10=array_slice ($ary, 0, 10), and/or remove the smallest 10 values
$max _10=array_slice ($ary, 10 , 10)//Remove the largest 10 numeric
rsort ($max _10);//reverse order the largest 10 numeric
echo ' <pre> ';
Print_r ($min _10);
Print_r ($max _10);
Unset ($ary, $min _10, $max _10);

2. The results of the operation are as follows:

Array

  [2] =>
  [3] => to
  [4] =>
  [5] => 49
  [6] => [

  [7] => 99933
  [8] => 99927
  [9] => 99900
