PHP opendir() to list folders only
提问by Jeff Thomas
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?
我想使用 opendir() 仅列出特定文件夹（即 /www/site/）中的文件夹。我想从列表中排除文件以及 '.' 和 '..' 文件夹出现在 linux 文件夹列表中。我该怎么做呢？

foreach(glob('directory/*', GLOB_ONLYDIR) as $dir) {
$dir = str_replace('directory/', '', $dir);
echo $dir;
}
You can use simply glob with GLOB_ONLYDIR and then filter resulted directories
您可以简单地将 glob 与 GLOB_ONLYDIR 一起使用，然后过滤结果目录

Check out the PHP docs for readdir(). It includes an example for exactly this.
For completeness:
为了完整性：
<?php
if ($handle = opendir('.')) {
$blacklist = array('.', '..', 'somedir', 'somefile.php');
while (false !== ($file = readdir($handle))) {
if (!in_array($file, $blacklist)) {
echo "$file\n";
}
}
closedir($handle);
}
?>
Simply change opendir('.')to your directory, i.e. opendir('/www/sites/'), and update $blacklistto include the names of files or directory you do not wish to output.
只需更改opendir('.')到您的目录，即opendir('/www/sites/')，然后更新$blacklist以包含您不想输出的文件或目录的名称。

function scandir_nofolders($d) {
return array_filter(scandir($d), function ($f) use($d) {
return ! is_dir($d . DIRECTORY_SEPARATOR . $f);
});
}
This function returns an array you can iterate over or store somewhere, which is what 99.37% of all programmers using opendirwant.
这个函数返回一个你可以迭代或存储在某个地方的数组，这是 99.37% 使用的程序员opendir想要的。

List only folders (Directories):
仅列出文件夹（目录）：
<?php
$Mydir = ''; ### OR MAKE IT 'yourdirectory/';
foreach(glob($Mydir.'*', GLOB_ONLYDIR) as $dir) {
$dir = str_replace($Mydir, '', $dir);
echo $dir;
}
?>

Try this with glob('*')function
试试这个glob('*')功能
<?php
$dirs = array_filter(glob('*'), 'is_dir');
$i = 1;
foreach ($dirs as $value) {
echo $i . '. <a href = "http://localhost/' . $value . '" target = "_blank">' . $value . '</a><br>';
$i++;
}
?>
Above code worked for me for list out folders in current directory and I further developed code to open each folder in a new tab in same browser. This is shows only directories.
上面的代码对我有用，用于列出当前目录中的文件夹，我进一步开发了代码以在同一浏览器的新选项卡中打开每个文件夹。这仅显示目录。

Can also be used in forms to create a Dropdown of Folder names (here it is the images folder). Ensures that a user uploading an image pushes it to the correct folder :-)
也可以在表单中使用以创建文件夹名称下拉列表（这里是图像文件夹）。确保上传图像的用户将其推送到正确的文件夹:-)
<select name="imgfolder">
<option value="genimage">General Image</option>
<?php
$Mydir = '../images/'; // use 'anydirectory_of_your_choice/';
foreach(glob($Mydir.'*', GLOB_ONLYDIR) as $dir) {
$dirname = basename($dir) ;
echo '<option value="' . $dirname . '">' . $dirname . '</option>' ;
}
?>
</select>
