PHP列出目录中的所有文件

Question

我曾看到列出目录中所有文件的函数，但如何列出所有子目录中的文件，以便它返回一个像以下这样的数组？
获取具有PHP目录结构
使用PHP获取目录中所有文件的名称

$files = files("foldername");

所以，$files 类似于什么

array("file.jpg", "blah.word", "name.fileext")

Answer 1

foreach (new RecursiveIteratorIterator(new RecursiveDirectoryIterator('.')) as $filename)
{
    // filter out "." and ".."
    if ($filename->isDir()) continue;

    echo "$filename\n";
}

PHP文档：

• RecursiveDirectoryIterator
• RecursiveIteratorIterator

支持使用SPL。我认为现在（已经有一段时间了）应该开始使用SPL，而不是使用庞大、缓慢的过程块。 - superultranova

完整代码（更改文件夹名）- <?php$path = realpath('你的文件夹名/示例文件夹名');foreach (new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path)) as $filename){`echo "$filename\n";`}?> - T.Todua

哇，与上面的巨兽相比，这个简直太惊人了。 - Kloar

它包括 . 和..特殊目录。希望您可以通过添加一个！$filename->isDir()测试来过滤它们（没有isDot()，请参见SplFileInfo）。 - Gras Double

所以你正在寻找一个递归的目录列表？

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;
}

不要在递归中使用正则表达式，它们往往非常慢！在您的情况下，请使用 rtrim 函数。 - machineaddict

我将其重写为要更高效并仅返回文件的gist：https://gist.github.com/brucekirkpatrick/8528710 - Bruce Kirkpatrick

Answer 3

我认为你正在寻找php的glob函数。你可以调用glob(**)来获取递归文件列表。

编辑：我意识到我的glob在所有系统上都不能可靠地工作，因此我提交了这个更漂亮的版本的被接受答案。

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;
}

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']));

我需要实现读取给定目录的功能，并依赖于Chuck Vose的函数，因此我创建了这个页面来使用JQuery读取目录：

<?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"]);
?>
