PHP opendir()仅列出文件夹 [英] PHP opendir() to list folders only

问题描述

我想使用opendir()仅列出特定文件夹(即/www/site/)中的文件夹.我也想从列表中排除文件.和出现在linux文件夹列表中的".."文件夹.我将如何去做?

I would like to use opendir() to list only the folders in a particular folder (i.e. /www/site/). I would like to exclude files from the list as well at the '.' and '..' folders that appear on a linux folder listing. How would I go about doing this?

推荐答案

查看 PHP文档中的readdir().它包括一个确切的例子.

Check out the PHP docs for readdir(). It includes an example for exactly this.

出于完整性考虑:

<?php
if ($handle = opendir('.')) {
    $blacklist = array('.', '..', 'somedir', 'somefile.php');
    while (false !== ($file = readdir($handle))) {
        if (!in_array($file, $blacklist)) {
            echo "$file\n";
        }
    }
    closedir($handle);
}
?>

只需将opendir('.')更改为目录，即opendir('/www/sites/')，并更新$blacklist以包括您不希望输出的文件或目录的名称.

Simply change opendir('.') to your directory, i.e. opendir('/www/sites/'), and update $blacklist to include the names of files or directory you do not wish to output.
