【中文标题】PHP列出目录中的所有文件[重复]【英文标题】:PHP list all files in directory [duplicate] 【发布时间】:2022-01-10 12:14:15 【问题描述】:可能重复:Get the hierarchy of a directory with phpGetting the names of all files in a directory with PHP
我见过列出目录中的所有文件的功能,但是我怎样才能列出子目录中的所有文件,所以它返回一个数组喜欢吗?
$files = files("foldername");
所以$files
类似于
array("file.jpg", "blah.word", "name.fileext")
【问题讨论】:
【参考方案1】:foreach (new RecursiveIteratorIterator(new RecursiveDirectoryIterator('.')) as $filename)
// filter out "." and ".."
if ($filename->isDir()) continue;
echo "$filename\n";
PHP 文档:
RecursiveDirectoryIterator RecursiveIteratorIterator【讨论】:
SPL 为 +1。 IMO 是时候(已经有一段时间了)开始使用 SPL 而不是这些巨大而缓慢的程序块了。 完整代码(更改文件夹名称)-<?php
$path = realpath('yourfolder/examplefolder');
foreach (new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path)) as $filename)
echo "$filename\n";
?>
哦哇...与上面的庞然大物相比。太棒了。
它包括.
和..
特殊目录。希望您可以通过添加!$filename->isDir()
测试将它们过滤掉(没有isDot()
,请参阅SplFileInfo)。
另外,还有指向 PHP 文档的有用链接:RecursiveDirectoryIterator - RecursiveIteratorIterator【参考方案2】:
所以您正在寻找递归目录列表?
function directoryToArray($directory, $recursive)
$array_items = array();
if ($handle = opendir($directory))
while (false !== ($file = readdir($handle)))
if ($file != "." && $file != "..")
if (is_dir($directory. "/" . $file))
if($recursive)
$array_items = array_merge($array_items, directoryToArray($directory. "/" . $file, $recursive));
$file = $directory . "/" . $file;
$array_items[] = preg_replace("/\/\//si", "/", $file);
else
$file = $directory . "/" . $file;
$array_items[] = preg_replace("/\/\//si", "/", $file);
closedir($handle);
return $array_items;
【讨论】:
不要在递归中使用正则表达式,它们往往很慢!在您的情况下使用 rtrim 功能。 我将其重写为一个要点,以提高效率并且只返回文件:gist.github.com/brucekirkpatrick/8528710【参考方案3】:我认为您正在寻找php's glob function。您可以致电glob(**)
获取递归文件列表。
编辑:我意识到我的 glob 不能在所有系统上可靠地工作,所以我提交了这个更漂亮的已接受答案版本。
function rglob($pattern='*', $flags = 0, $path='')
$paths=glob($path.'*', GLOB_MARK|GLOB_ONLYDIR|GLOB_NOSORT);
$files=glob($path.$pattern, $flags);
foreach ($paths as $path) $files=array_merge($files,rglob($pattern, $flags, $path));
return $files;

【参考方案4】:function files($path,&$files = array())
$dir = opendir($path."/.");
while($item = readdir($dir))
if(is_file($sub = $path."/".$item))
$files[] = $item;else
if($item != "." and $item != "..")
files($sub,$files);
return($files);
print_r(files($_SERVER['DOCUMENT_ROOT']));

【参考方案5】:我需要实现对给定目录的读取,依靠Chuck Vose的功能,我创建了这个页面来读取依赖JQuery的目录:
<?php
/**
* Recovers folder structure and files of a certain path
*
* @param string $path Folder where files are located
* @param string $pattern Filter by extension
* @param string $flags Flags to be passed to the glob
* @return array Folder structure
*/
function getFolderTree($path)
//Recovers files and directories
$paths = glob($path . "*", GLOB_MARK | GLOB_ONLYDIR | GLOB_NOSORT);
$files = glob($path . "*");
//Traverses the directories found
foreach ($paths as $key => $path)
//Create directory if exists
$directory = explode("\\", $path);
unset($directory[count($directory) - 1]);
$directories[end($directory)] = getFolderTree($path);
//Verify if exists files
foreach ($files as $file)
if (strpos(substr($file, 2), ".") !== false)
$directories[] = substr($file, (strrpos($file, "\\") + 1));
//Return the directories
if (isset($directories))
return $directories;
//Returns the last level of folder
else
$files2return = Array();
foreach ($files as $key => $file)
$files2return[] = substr($file, (strrpos($file, "\\") + 1));
return $files2return;
/**
* Creates the html for the tree
*
* @param array $directory Array containing the folder structure
* @return string HTML
*/
function createTree($directory)
$html = "<ul>";
foreach($directory as $keyDirectory => $eachDirectory)
if(is_array($eachDirectory))
$html .= "<li class='closed'><span class='folder'>" . $keyDirectory . "</span>";
$html .= createTree($eachDirectory);
$html .= "</li>";
else
$html .= "<li><span class='file'>" . $eachDirectory . "</span></li>";
$html .= "</ul>";
return $html;
//Create output
$directory = getFolderTree('..\videos');
$htmlTree = createTree($directory["videos"]);
?>

<body>
<div id="main">
<ul id="browser" class="filetree">
<?php echo $htmlTree;?>
</ul>
</div>
</body>
</html>
用JQuery的树中使用的结构,取的站点是: http://jquery.bassistance.de/treeview/demo/
希望有用!
