Get folders with PHP glob - unlimited levels deep
提问by Jens T?rnell
I have this working function that finds folders and creates an array.
我有这个工作功能，可以找到文件夹并创建一个数组。
function dua_get_files($path)
{
foreach (glob($path . "/*", GLOB_ONLYDIR) as $filename)
{
$dir_paths[] = $filename;
}
return $dir_paths;
}
This function can only find the directories on the current location. I want to find the directory paths in the child folders and their children and so on.
此功能只能查找当前位置上的目录。我想在子文件夹及其子文件夹中找到目录路径等等。
The array should still be a flat list of directory paths.
该数组仍应是目录路径的平面列表。
An example of how the output array should look like
输出数组的外观示例
$dir_path[0] = 'path/folder1';
$dir_path[1] = 'path/folder1/child_folder1';
$dir_path[2] = 'path/folder1/child_folder2';
$dir_path[3] = 'path/folder2';
$dir_path[4] = 'path/folder2/child_folder1';
$dir_path[5] = 'path/folder2/child_folder2';
$dir_path[6] = 'path/folder2/child_folder3';

If you want to recursively work on directories, you should take a look at the RecursiveDirectoryIterator.
如果你想递归地处理目录，你应该看看RecursiveDirectoryIterator.
$path = realpath('/etc');
$objects = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path), RecursiveIteratorIterator::SELF_FIRST);
foreach($objects as $name => $object){
echo "$name\n";
}

Very strange - everybody advice recursion, but better just cycle:
很奇怪 - 每个人都建议递归，但最好只是循环：
$dir ='/dir';
while($dirs = glob($dir . '/*', GLOB_ONLYDIR)) {
$dir .= '/*';
if(!$result) {
$result = $dirs;
} else {
$result = array_merge($result, $dirs);
}
}

Try this instead:
试试这个：
function dua_get_files($path)
{
$data = array();
$files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path), RecursiveIteratorIterator::SELF_FIRST);
foreach ($files as $file)
{
if (is_dir($file) === true)
{
$data[] = strval($file);
}
}
return $data;
}

Use this function :
使用此功能：
function dua_get_files($path)
{
$dir_paths = array();
foreach (glob($path . "/*", GLOB_ONLYDIR) as $filename)
{
$dir_paths[] = $filename;
$a = glob("$filename/*", GLOB_ONLYDIR);
if( is_array( $a ) )
{
$b = dua_get_files( "$filename/*" );
foreach( $b as $c )
{
$dir_paths[] = $c;
}
}
}
return $dir_paths;
}

You can use php GLOB function, but you must create a recursive function to scan directories at infinite level depth. Then store results in a global variable.
您可以使用 php GLOB 函数，但您必须创建一个递归函数来扫描无限级深度的目录。然后将结果存储在全局变量中。
function dua_get_files($path) {
global $dir_paths; //global variable where to store the result
foreach ($path as $dir) { //loop the input
$dir_paths[] = $dir; //can use also "basename($dir)" or "realpath($dir)"
$subdir = glob($dir . DIRECTORY_SEPARATOR . '*', GLOB_ONLYDIR); //use DIRECTORY_SEPARATOR to be OS independent
if (!empty($subdir)) { //if subdir is not empty make function recursive
dua_get_files($subdir); //execute the function again with current subdir
}
}
}
//usage:
$path = array('galleries'); //suport absolute or relative path. support one or multiple path
dua_get_files($path);
print('<pre>'.print_r($dir_paths,true).'</pre>'); //debug

For PHP, if you are on a linux/unix, you can also use backticks (shell execution) with the unix findcommand. Directory searching on the filesystem can take a long time and hit a loop -- the system findcommand is already built for speed and to handle filesystem loops. In other words, the system exec call is likely to cost far less cpu-time than using PHP itself to search the filesystem tree.
对于PHP，如果您使用的是 linux/unix，您还可以在 unixfind命令中使用反引号（shell 执行）。文件系统上的目录搜索可能需要很长时间并遇到循环——系统find命令已经为速度和处理文件系统循环而构建。换句话说，系统 exec 调用可能比使用 PHP 本身搜索文件系统树花费的 CPU 时间少得多。
$dirs = `find $path -type d`;
Remember to sanitize the $path input, so other users don't pass in security compromising path names (like from the url or something).
请记住清理 $path 输入，这样其他用户就不会传入危害安全的路径名（例如来自 url 或其他内容）。
To put it into an array
将其放入数组
$dirs = preg_split("/\s*\n+\s*/",`find $path -type d`,-1,PREG_SPLIT_NO_EMPTY);
