//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);
