Question

我想按字母顺序对文件进行排序，但我不知道该怎么做。我的意思是，我希望目录将是ABC订单的第一个目录，以及ABC订购的文件之后。我尝试了几种选择，但我不能这样做。这是我的代码：

<?php

    $dirlist = getFileList("./members/files/");?>

    <table border="1">
        <thead>
            <tr>
                <th>Name</th>
                <th>Type</th>
                <th>Size</th>
                <th>Last Modified</th>
            </tr>
        </thead>
        <tbody>
            <?php
            // output file list as table rows
            foreach($dirlist as $file) {
                echo "<tr>\n";

                    $file['nams'] = basename($file['name']);
                    $file['nams2'] = pathinfo($file['nams'], PATHINFO_EXTENSION );
                    $file['nams'] = pathinfo($file['nams'], PATHINFO_FILENAME);

                    if($file['nams2'] != 'mp4' && $file['nams2'] != '')
                    {
                        echo "<td><a href=\"/members/get_file.php?name={$file['nams']}&ext={$file['nams2']}\">",basename($file['name']),"</a></td>\n";
                    } else if($file['nams2'] != '') {
                        echo "<td><a href=\"/video.php?name={$file['nams']}\">",basename($file['name']),"</a></td>\n";
                    } else {
                        echo "<td><a href=\"#\">",basename($file['name']),"</a></td>\n";
                    }

                    echo "<td>{$file['type']}</td>\n";
                    echo "<td>{$file['size']}</td>\n";
                    echo "<td>",date('Y-m-d H:i', $file['lastmod']),"</td>\n";

                echo "</tr>\n";
            }
            ?>
        </tbody>
    </table>

    <?php
    function getFileList($dir, $recurse=false, $depth=false)
    {
        $retval = array();

        // add trailing slash if missing
        if(substr($dir, -1) != "/") $dir .= "/";

        // open pointer to directory and read list of files
        $d = @dir($dir) or die("getFileList: Failed opening directory $dir for reading");
        while(false !== ($entry = $d->read())) {
            // skip hidden files
            if($entry[0] == ".") continue;
            if(is_dir("$dir$entry")) {
                $retval[] = array(
                    "name" => "$dir$entry/",
                    "type" => filetype("$dir$entry"),
                    "size" => 0,
                    "lastmod" => filemtime("$dir$entry")
                );
                if($recurse && is_readable("$dir$entry/")) {
                    if($depth === false) {
                        $retval = array_merge($retval, getFileList("$dir$entry/", true));
                    } elseif($depth > 0) {
                        $retval = array_merge($retval, getFileList("$dir$entry/", true, $depth-1));
                    }
                }
            } elseif(is_readable("$dir$entry")) {
                $retval[] = array(
                  "name" => "$dir$entry",
                  "type" => mime_content_type("$dir$entry"),
                  "size" => formatSizeUnits(filesize("$dir$entry")),
                  "lastmod" => filemtime("$dir$entry")
                );
            }
        }
        $d->close();

        return $retval;
    }

    function formatSizeUnits($bytes)
    {
        if ($bytes >= 1073741824)
        {
            $bytes = number_format($bytes / 1073741824, 2) . ' GB';
        }
        elseif ($bytes >= 1048576)
        {
            $bytes = number_format($bytes / 1048576, 2) . ' MB';
        }
        elseif ($bytes >= 1024)
        {
            $bytes = number_format($bytes / 1024, 2) . ' kB';
        }
        elseif ($bytes > 1)
        {
            $bytes = $bytes . ' bytes';
        }
        elseif ($bytes == 1)

您可以使用scandir以数组的形式返回已排序的文件列表。

示例：

<?php $directory_list = scandir("./members/files/"); print_r($directory_list);

这将输出类似于：
的目录列表
Array ( [0] => . [1] => .. [2] => bar.php [3] => foo.txt [4] => somedir ... )

你可以这样做，按降序排序：

print_r($directory_list, SCANDIR_SORT_DESCENDING);

您可以在PHP documentation中找到有关scandir的更多信息。
