大家好，我有什么误解吗?
$dir = get_bloginfo('template_url').'/images/headers/';
echo $dir;
//ouput: myblog.com/wp-content/themes/mytheme/images/headers
$dir = new DirectoryIterator(get_bloginfo('template_url').'/images/headers/');
echo $dir;
//output: nothing at all! blank page!
控制台输出一个fatal_error:

你知道这里出了什么问题吗?
看起来您传递的是URL而不是路径:
DirectoryIterator->__construct('http://oberperf...')
您应该将目录的完整本地路径名传递给构造函数。
我很确定路径必须是文档根目录的绝对路径，而不是URL。
尝试get_template_directory()代替:
$dir = new DirectoryIterator( get_template_directory() . '/images/headers/');
echo $dir;
