PHP: Simplest way to delete a folder (including its contents)
提问by Chris B
The rmdir()function fails if the folder contains any files. I can loop through all of the the files in the directory with something like this:
rmdir()如果文件夹包含任何文件，该函数将失败。我可以使用以下内容遍历目录中的所有文件：
foreach (scandir($dir) as $item) {
if ($item == '.' || $item == '..') continue;
unlink($dir.DIRECTORY_SEPARATOR.$item);
}
rmdir($dir);
Is there any way to just delete it all at once?
有没有办法一次性全部删除？

As per thissource;
根据这个来源；
Save some time, if you want to clean a directory or delete it and you're on windows.
节省一些时间，如果你想清理一个目录或删除它并且你在 Windows 上。
Use This:
用这个：
chdir ($file_system_path);
exec ("del *.* /s /q");
You can use other DEL syntax, or any other shell util. You may have to allow the service to interact with the desktop, as that's my current setting and I'm not changing it to test this.
您可以使用其他 DEL 语法或任何其他 shell 实用程序。您可能必须允许服务与桌面交互，因为这是我当前的设置，我不会更改它来测试它。
Else you could find an alternative method here.

lprent 位于 php 注释中的一个安全且良好的功能 它可以防止意外删除位于当前目录中的符号链接目录的内容
