PHP - 计算字符串出现在文件中的次数 [英] PHP - Count number of times string appears in file

问题描述

我有一个文件（leaderboard.txt），看起来像这样：

  funkystudios 
 funkystudios 
 funkystudios 
 gilletteracer74 
 axehairgel 
 Ferby123 
 dirdam 
 TheWu13 
 Expert_Assassin 
 TheWu13 
 ocanosoup 
  

我希望能够读取此文件，并打印出每个人在文件中出现的次数。 （也可按文件中的次数排列）

  funkystudios：3 
 TheWu13：2 
 gilletteracer74：1 
 axehairgel：1 
（依此类推）
  



已经尝试了各种方式，但这一切都归结为一个问题，当我试图正确地命令他们...我猜是有一个非常简单的方法来做到这一点。 （我是新来的PHP ...）



编辑：
我已经到了这个地步：

$ b $

  foreach（array_count_values（file（'leaderboard.txt'））as $ person => $ count）
 echo{$ person}：{$ count}< br /> \r\\\
; 
  

它并不按$ count排序，而只是在文件中首先出现。 / p>

解决方案

  $ counts = array_count_values（file（'leaderboard.txt'））; 
 
 arsort（$ count）; 
 $ b foreach（$ count as $ person => $ count）
 echo{$ person}：{$ count}< br /> \r\\\
; 
  

I've got a file (leaderboard.txt) that looks like this:

funkystudios
funkystudios
funkystudios
gilletteracer74
axehairgel
Ferby123
dirdam
TheWu13
Expert_Assassin
TheWu13
ocanosoup

I want to be able to read this file, and print out the number of times each person appears in the file. (Also place in order of # of times in file)

funkystudios: 3
TheWu13: 2
gilletteracer74: 1
axehairgel: 1
(and so on)

I've tried various ways but It all came down to an issue when I would try to order them correctly... I'm guessing there is a pretty easy way to do this. (I'm new to PHP...)

EDIT: I have gotten to this point:

  foreach(array_count_values(file('leaderboard.txt')) as $person => $count)
echo "{$person} : {$count}<br />\r\n";

It doesn't order by the $count, but simply who comes up first in the file.

解决方案

$counted = array_count_values(file('leaderboard.txt'));

arsort($counted);

  foreach($counted as $person => $count)
        echo "{$person} : {$count}<br />\r\n";
