You can use the <a href="http://de.php.net/manual/en/directoryiterator.construct.php" rel="noreferrer">DirectoryIterator</a>. Example from php Manual:

<pre><code>&lt;?php
$dir = new DirectoryIterator(dirname(__FILE__));

If you don't have access to DirectoryIterator class try this:

<pre><code>&lt;?php
$path = "/path/to/files";

if ($handle = opendir($path)) {
 while (false !== ($file = readdir($handle))) {
 if ('.' === $file) continue;
 if ('..' === $file) continue;

 // do something with the file

Use the <code>scandir()</code> function: 

<pre><code>&lt;?php
 $directory = '/path/to/files';

 if (!is_dir($directory)) {
 exit('Invalid diretory path');
 }

 $files = array();
 foreach (scandir($directory) as $file) {
 if ($file !== '.' &amp;&amp; $file !== '..') {
 $files[] = $file;
 }
 }

 var_dump($files);
?&gt;
</code></pre>

blocks|key|874128|text|您还可以使用FilesystemIterator。它需要比DirectoryIterator更少的代码，并自动删除.和..。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|874129|//+Let's+traverse+the+images+directory

You can also make use of <code>FilesystemIterator</code>. It requires even less code then <code>DirectoryIterator</code>, and automatically removes <code>.</code> and <code>..</code>.

<pre><code>// Let's traverse the images directory
$fileSystemIterator = new FilesystemIterator('images');

$entries = array();
foreach ($fileSystemIterator as $fileInfo){
 $entries[] = $fileInfo-&gt;getFilename();
}

var_dump($entries);

//OUTPUT
object(FilesystemIterator)[1]

array (size=14)
 0 =&gt; string 'aa[1].jpg' (length=9)
 1 =&gt; string 'Chrysanthemum.jpg' (length=17)
 2 =&gt; string 'Desert.jpg' (length=10)
 3 =&gt; string 'giphy_billclinton_sad.gif' (length=25)

blocks|key|874051|text|glob()提供了排序和模式匹配功能。由于返回值是一个数组，因此您可以执行所需的大多数其他操作。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|874052|entityMap|0|LINK|mutability|MUTABLE|url|http://php.net/manual/en/function.glob.php^0|0|6|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

<a href="http://php.net/manual/en/function.glob.php" rel="nofollow">glob()</a> has provisions for sorting and pattern matching. Since the return value is an array, you can do most of everything else you need.

blocks|key|1088902|text|大多数时候，我想你会想要跳过.和..。下面是使用递归的方法：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1088903|<?php

Most of the time I imagine you want to skip <code>.</code> and <code>..</code>. Here is that with
recursion:
<pre><code>&lt;?php

$rdi = new RecursiveDirectoryIterator('.', FilesystemIterator::SKIP_DOTS);
$rii = new RecursiveIteratorIterator($rdi);

foreach ($rii as $di) {
 echo $di-&gt;getFilename(), &quot;\n&quot;;
}

For completeness (since this seems to be a high-traffic page), let's not forget the good old <a href="http://php.net/manual/en/function.dir.php" rel="nofollow noreferrer"><code>dir()</code> function</a>:

I'm looking for a PHP script that loops through all of the files in a directory so I can do things with the filename, such as format, print or add it to a link. I'd like to be able to sort the files by name, type or by date created/added/modified. (Think fancy directory "index".) I'd also like to be able to add exclusions to the list of files, such as the script itself or other "system" files. (Like the <code>.</code> and <code>..</code> "directories".)

Being that I'd like to be able to modify the script, I'm more interested in looking at the PHP docs and learning how to write one myself. That said, if there are any existing scripts, tutorials and whatnot, please let me know.

PHP script to loop through all of the files in a directory?

我正在寻找一个PHP脚本，它可以遍历目录中的所有文件，这样我就可以对文件名执行一些操作，例如格式化、打印或将其添加到链接。我希望能够按名称、类型或按创建/添加/修改的日期对文件进行排序。(想想花哨的目录“index”。)我还希望能够将排除项添加到文件列表中，例如脚本本身或其他“系统”文件。(就像.和..的“目录”。)因为我希望能够修改脚本，所以我更感兴趣的是查看PHP文档并学习如何自己编写PHP文
