嗨，我正在尝试使用 php 显示目录中的所有文件和文件夹
e.g
例如
Dir: system/infomation/
目录：系统/信息/
Folder- User
文件夹- 用户
Files From User- User1.txt
来自用户的文件- User1.txt
Files From User- User2.txt
来自用户的文件- User2.txt
Files From User- User3.txt
来自用户的文件- User3.txt
Files From User- User4.txt
来自用户的文件- User4.txt
Folder - Players
文件夹 -玩家
Files From Players- Player1.txt
来自玩家的文件- Player1.txt
Files From Players- Player2.txt
来自玩家的文件- Player2.txt
Files From Players- Player3.txt
来自玩家的文件- Player3.txt
Files From Players- Player4.txt
来自玩家的文件- Player4.txt
Can someone lead me down the right street please
有人能带我走正确的街道吗

PHP 5 has the RecursiveDirectoryIterator.
PHP 5 具有RecursiveDirectoryIterator.
The manual has a basic example:
该手册有一个基本示例：
<?php
$directory = '/system/infomation/';
$it = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($directory));
while($it->valid()) {
if (!$it->isDot()) {
echo 'SubPathName: ' . $it->getSubPathName() . "\n";
echo 'SubPath: ' . $it->getSubPath() . "\n";
echo 'Key: ' . $it->key() . "\n\n";
}
$it->next();
}
?>
Edit-- Here's a slightly more advanced example (only slightly) which produces output similar to what you want (i.e. folder names then files).
编辑- 这是一个稍微更高级的示例（只是稍微），它产生的输出类似于您想要的（即文件夹名称然后是文件）。
// Create recursive dir iterator which skips dot folders
$dir = new RecursiveDirectoryIterator('./system/information',
FilesystemIterator::SKIP_DOTS);
// Flatten the recursive iterator, folders come before their files
$it = new RecursiveIteratorIterator($dir,
RecursiveIteratorIterator::SELF_FIRST);
// Maximum depth is 1 level deeper than the base folder
$it->setMaxDepth(1);
// Basic loop displaying different messages based on file or folder
foreach ($it as $fileinfo) {
if ($fileinfo->isDir()) {
printf("Folder - %s\n", $fileinfo->getFilename());
} elseif ($fileinfo->isFile()) {
printf("File From %s - %s\n", $it->getSubPath(), $fileinfo->getFilename());
}
}

//path to directory to scan
$directory = "../data/team/";
//get all text files with a .txt extension.
$texts = glob($directory . "*.txt");
//print each file name
foreach($texts as $text)
{
echo $text;
}

You can use:
您可以使用：
foreach (new DirectoryIterator("./system/information/") as $fn) {
print $fn->getFilename();
}
You'll have to use it twice for each subdir, Players and User.
您必须为每个子目录、玩家和用户使用它两次。

回答by Abooddy Hello
use this function http://www.codingforums.com/showthread.php?t=71882
使用这个功能http://www.codingforums.com/showthread.php?t=71882
function getDirectory( $path = '.', $level = 0 ){
$ignore = array( 'cgi-bin', '.', '..' );
// Directories to ignore when listing output. Many hosts
// will deny PHP access to the cgi-bin.
$dh = @opendir( $path );
// Open the directory to the handle $dh
while( false !== ( $file = readdir( $dh ) ) ){
// Loop through the directory
if( !in_array( $file, $ignore ) ){
// Check that this file is not to be ignored
$spaces = str_repeat( ' ', ( $level * 4 ) );
// Just to add spacing to the list, to better
// show the directory tree.
if( is_dir( "$path/$file" ) ){
// Its a directory, so we need to keep reading down...
echo "<strong>$spaces $file</strong><br />";
getDirectory( "$path/$file", ($level+1) );
// Re-call this same function but on a new directory.
// this is what makes function recursive.
} else {
echo "$spaces $file<br />";
// Just print out the filename
}
}
}
closedir( $dh );
// Close the directory handle
}
and call the function like that
并像这样调用函数
getDirectory( "." );
// Get the current directory
getDirectory( "./files/includes" );
// Get contents of the "files/includes" folder

You may use Directory Functions: http://php.net/manual/en/book.dir.php
您可以使用目录功能：http: //php.net/manual/en/book.dir.php
Simple example from opendir()function description:
来自opendir()函数描述的简单示例：
<?php
$dir_path = "/path/to/your/dir";
if (is_dir($dir_path)) {
if ($dir_handler = opendir($dir_path)) {
while (($file = readdir($dir_handler)) !== false) {
echo "filename: $file : filetype: " . filetype($dir_path . $file) . "\n";
}
closedir($dir_handler);
}
}

Use the Dir class or opendir()and readdir()in a recursive function.
在递归函数中使用 Dir 类或opendir()和readdir()。

I've found in www.laughing-buddha.net/php/lib/dirlist/ a function that returns an array containing a list of a directory's contents.
我在 www.laughing-buddha.net/php/lib/dirlist/ 中找到了一个函数，该函数返回一个包含目录内容列表的数组。
Also look at php.net http://es.php.net/manual/es/ref.filesystem.phpwhere you'll find additional functions for working with files in php.

Have a look at building a simple directory browser using php RecursiveDirectoryIterator

Also, as you mentioned you want to list you can also look at some ready made libraries that create file/folder explorers e.g.:
