您好我试图用php
显示目录中的所有文件和文件夹e.g
主持人： system / infomation /
文件夹 - 用户
来自用户的文件 - User1.txt
来自用户的文件 - User2.txt
来自用户的文件 - User3.txt
来自用户的文件 - User4.txt
文件夹 - 玩家
来自玩家的文件 - Player1.txt
来自玩家的文件 - Player2.txt
来自玩家的文件 - Player3.txt
来自玩家的文件 - Player4.txt
有人可以带我到正确的街道去吗
谢谢

PHP 5有RecursiveDirectoryIterator。
手册有一个基本的例子：
<?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();
}
?>
编辑 - 这是一个稍微高级的示例（仅略微），它会产生类似于您想要的输出（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;

文件夹中的列表文件 - 1解决方案
<?php
// open this directory
$myDirectory = opendir(".");
// get each entry
while($entryName = readdir($myDirectory)) {
$dirArray[] = $entryName;
}
// close directory
closedir($myDirectory);
// count elements in array
$indexCount = count($dirArray);
Print ("$indexCount files<br>\n");
// sort 'em
sort($dirArray);
// print 'em
print("<TABLE border=1 cellpadding=5 cellspacing=0 class=whitelinks>\n");
print("<TR><TH>Filename</TH><th>Filetype</th><th>Filesize</th></TR>\n");
// loop through the array of files and print them all
for($index=0; $index < $indexCount; $index++) {
if (substr("$dirArray[$index]", 0, 1) != "."){ // don't list hidden files
print("<TR><TD><a href=\"$dirArray[$index]\">$dirArray[$index]</a></td>");
print("<td>"); print(filetype($dirArray[$index])); print("</td>");
print("<td>"); print(filesize($dirArray[$index])); print("</td>");
print("</TR>\n");
}
}
print("</TABLE>\n");

您可以使用：
foreach (new DirectoryIterator("./system/information/") as $fn) {
print $fn->getFilename();
}
您必须为每个子目录，玩家和用户使用两次。

使用此功能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
}
并像这样调用函数
getDirectory( "." );
// Get the current directory
getDirectory( "./files/includes" );
// Get contents of the "files/includes" folder

您可以使用目录功能：http://php.net/manual/en/book.dir.php
来自opendir()功能描述的简单示例：
<?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);
}
}
?>

如果您在访问路径时遇到问题，可能需要输入：

$path = "/cv/";
// Open the folder
$dir_handle = @opendir($root . $path) or die("Unable to open $path");
