我有一个文件夹,里面装满了空文件夹和完整文件夹.
我想迭代所有这些,找出它们是否为空,如果是,则删除它们.我已经看到了一些可以应用的问题,但我无法弄清楚整个解决方案:
使用新的PHP5函数必须有一些简单的确定方法吗?
像(伪代码充满错误)
<?php
$dir = new DirectoryIterator('/userfiles/images/models/');
foreach ($dir as $fileinfo) {
if (!$fileinfo->isDot()) {
if(!(new \FilesystemIterator($fileinfo))->valid()) {
rmdir($fileinfo);
}
}
}
?>

这应该适合你:
在这里,我只是从特定路径获取所有目录glob()(PHP 4> = 4.3.0,PHP 5).然后我遍历每个目录并检查它是否为空.
如果它是空的我用rmdir()else 删除它我检查是否有另一个direcotry并用新目录调用该函数
<?php
function removeEmptyDirs($path, $checkUpdated = false, $report = false) {
$dirs = glob($path . "/*", GLOB_ONLYDIR);
foreach($dirs as $dir) {
$files = glob($dir . "/*");
$innerDirs = glob($dir . "/*", GLOB_ONLYDIR);
if(empty($files)) {
if(!rmdir($dir))
echo "Err: " . $dir . "<br />";
elseif($report)
echo $dir . " - removed!" . "<br />";
} elseif(!empty($innerDirs)) {
removeEmptyDirs($dir, $checkUpdated, $report);
if($checkUpdated)
removeEmptyDirs($path, $checkUpdated, $report);
}
}
}
?>

举个例子:
如果这样$checkUpdated的TRUE结构被完全删除:
- dir
| - file.txt
| - dir
| - dir

结果:
- dir
| - file.txt

如果它FALSE像默认情况下那样结果将是:
- dir
| - file.txt
| - dir //See here this is still here
