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

The php code is as follows:

　?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

//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($i<=10){ printf("数字：%d 共出现 %d 次 ",$key,$value); }else{ break; } $i ; } unset($ary);

//Randomly generate numerical array for($i=0;$i<1000;$i ){<🎜> <🎜>$ary[]=rand(1,1000);<🎜> <🎜>}<🎜> <🎜>//Count the number of occurrences of all values ​​in the array<🎜> <🎜>$ary=array_count_values($ary);<🎜> <🎜>arsort($ary);//Sort in reverse order<🎜> <🎜>$i=1;<🎜> <🎜>foreach($ary as $key=>$value){ if($i<=10){<🎜> <🎜>printf("Number: %d appears %d times
",$key,$value); }else{ break; } $i ; } unset($ary);

The results are as follows: 　?

1 2 3 4 5 6 7 8 9 10

Number: 255 appears 6 times in total Number: 443 Appeared 5 times in total Number: 906 appears 5 times in total Number: 623 appears 5 times in total Number: 586 appears 4 times in total Number: 660 appears 4 times in total Number: 873 appears 4 times in total Number: 208 appears 4 times in total Number: 247 appears 4 times in total Number: 240 appears 4 times in total
