This article mainly introduces the method of counting the 10 most frequently occurring numbers in PHP array, involving the related usage skills of array_count_values and arsort and other methods in PHP, which is very It has practical value. Friends who need it can refer to
. This article describes the method of counting the 10 most frequently occurring numbers in a numerical array in PHP. Share it with everyone for your reference. The specific analysis is as follows:
This question belongs to the TOPK category. It is commonly used to count the frequency of word occurrences, make reports, and perform data statistics!
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 result is 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 数字:660 共出现 4 次 数字:873 共出现 4 次 数字:208 共出现 4 次 数字:247 共出现 4 次 数字:240 共出现 4 次
The above is the detailed content of How to count the most frequent numbers in an array in php. For more information, please follow other related articles on the PHP Chinese website!

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
