This article mainly introduced PHP to find a numerical array of not repeat the largest and smallest 10 number of methods, involving PHP Array_unique and Array_slice method of using the technique, very practical value, the need for friends can refer to the

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. as follows:

1. PHP code is as follows:

?

1 2 3 4 5 6 7 8 9 10 11 12-13

A randomly generated array of 10,000 elements for ($i =0 $i <10000; $i + +) {$ary []=rand (1,100000);} $ary =array_unique ($ary); To repeat the value sort ($ary);//Order $min _10=array_slice ($ary, 0, 10);//Remove the smallest 10 values $max _10=array_slice ($ary,-10, 10); Take out the largest 10 numerical 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);
