计算目录php中的多少个文件 [英] Count how many files in directory php

问题描述

我正在做一个稍微新的项目。

 < div id =我想知道如何让它计算在某个目录中有多少文件。 header> 
<？php 
 $ dir = opendir（'uploads /'）; ＃这是它将从
 $ i = 0计算的目录; ＃整数从0开始计数
 
＃false不等于目录
 while（false！==（$ file = readdir（$ dir）））{
 if（！in_array（$ file，array（'。'，'..'）和！is_dir（$ file））$ i ++; 
} 
 
 echo ;＃打印目录中有多少项目
？> 
< / div> 
  

b $ b

这是我到目前为止（从搜索），但它没有正确显示？我添加了一些笔记，所以随意删除他们，只是因此我可以理解它，可以。

如果您需要一些更多的信息或感觉，如果我没有描述这足够，请随时说出这样。

  $ fi = new FilesystemIterator（__ DIR__，FilesystemIterator :: SKIP_DOTS）; 
 printf（有％d个文件，iterator_count（$ fi））; 
  
I'm working on a slightly new project. I wanted to know how to make it so it counts how many files are in a certain directory.
<div id="header">
<?php 
    $dir = opendir('uploads/'); # This is the directory it will count from
    $i = 0; # Integer starts at 0 before counting

    # While false is not equal to the filedirectory
    while (false !== ($file = readdir($dir))) { 
        if (!in_array($file, array('.', '..') and !is_dir($file)) $i++;
    }

    echo "There were $i files"; # Prints out how many were in the directory
?>
</div>
This is what I have so far (from searching). However it is not appearing properly? I have added a few notes so feel free to remove them, they are just so I can understand it as best as I can.

If you require some more information or feel as if I haven't described this enough please feel free to state so.
解决方案
You can simply do the following :
$fi = new FilesystemIterator(__DIR__, FilesystemIterator::SKIP_DOTS);
printf("There were %d Files", iterator_count($fi));
