DirectoryIterator 扫描以排除“.”和'..'目录还包括它们吗？
在下面的脚本中，我尝试将 $base 目录中存在的文件夹复制到 $target 目录。然而，在我最初的回显测试中，它返回 .和 .. 目录，即使我试图在条件中处理该异常。
我缺少什么？
$base = dirname(__FILE__).'/themes/';
$target = dirname( STYLESHEETPATH );
$directory_folders = new DirectoryIterator($base);
foreach ($directory_folders as $folder)
{
if ($folder->getPath() !== '.' && $folder->getPath() !=='..' )
{
echo '<br>getPathname: '. $folder->getPathname();
//copy($folder->getPathname(), $target);
}
}die;
但是，如果我将条件更改为...，这对我来说毫无意义，
if (!is_dir($folder) && $folder->getPath() !== '.' && $folder->getPath() !=='..' )
它会返回 $base 内的正确文件夹。什么？
In the script below, I'm trying to copy the folders that exist in the $base directory over to the $target directory. However, in my initial echo test, its returning the . and .. directories even though I'm trying to handle that exception in the conditional.
What am I missing?
$base = dirname(__FILE__).'/themes/';
$target = dirname( STYLESHEETPATH );
$directory_folders = new DirectoryIterator($base);
foreach ($directory_folders as $folder)
{
if ($folder->getPath() !== '.' && $folder->getPath() !=='..' )
{
echo '<br>getPathname: '. $folder->getPathname();
//copy($folder->getPathname(), $target);
}
}die;
However, and this makes no sense to me, if I change the conditional to...
if (!is_dir($folder) && $folder->getPath() !== '.' && $folder->getPath() !=='..' )
It returns the correct folders inside of $base. What?

DirectoryIterator::getPath()返回目录的完整路径——而不仅仅是它的最后一部分。如果您只想要该路径的最后一部分，您可能应该使用
SplFileInfo::getBasename()在您的情况下。或者，对于您的特定测试，您可能需要查看
DirectoryIterator::isDot()方法（引用）：DirectoryIterator::getPath()returns the full path to the directory -- and not only the last part of it.If you only want the last portion of that path, you should probably use
SplFileInfo::getBasename()in your condition.Or, for your specific test, you might want to take a look at the
DirectoryIterator::isDot()method (quoting) :您可以使用 DirectoryIterator::isDot 代替：
You can use
DirectoryIterator::isDotinstead:
