This question belongs to the TOPK category. It is commonly used to count the frequency of word occurrences, make reports, and perform data statistics!

The php code is as follows:

//随机生成数值数组
for($i=0;$i<1000;$i++){
  $ary[]=rand(1,1000);
}
//统计数组中所有的值出现的次数
$ary=array_count_values($ary);
arsort($ary);//倒序排序
$i=1;
foreach($ary as $key=>$value){
  if($i<=10){
    printf("数字：%d 共出现 %d 次<br/>",$key,$value); 
  }else{
    break;
  }
  $i++;
}
unset($ary);

The results are as follows:

数字：255 共出现 6 次
数字：443 共出现 5 次
数字：906 共出现 5 次
数字：623 共出现 5 次
数字：586 共出现 4 次
