You want to delete the contents of a directory.
You want to delete everything recursively, all files and subdirectories.
$success = File::deleteDirectory($directory);
The method will return
false if the directory doesn't exist. Otherwise it returns
true when complete.
If you want to preserve the top level directory, pass a second argument.
$success = File::deleteDirectory($directory, true);
This will keep
$directory itself from being removed.
This method can quietly fail.
If there's an issue deleting one of the files, this method has the potential of failing quietly. It can return
true even if one or more files are not actually deleted.
If you're not preserving the top level directory, you can always perform a quick
File::exists() check on the directory to verify everything's been deleted.
