php directoryIterator问题 - 错误的路径？

Question

嘿家伙， 我在这里误解了什么？

$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! 

控制台拿出一个是fatal_error：

[26-Apr-2011] PHP Fatal error: Uncaught exception 'RuntimeException' with message 'DirectoryIterator::__construct(http://myblog.com/wp-content/themes/mytheme/images/headers/) [directoryiterator.--construct]: failed to open dir: not implemented' in /Users/myname/htdocs/myblog.com/wp-content/themes/mytheme/inc/header-image.php:3 Stack trace:

任何想法什么不顺心吗？

Answer 1

我敢肯定，路径必须是绝对的文档根目录，而不是URL。

尝试get_template_directory()代替：

$dir = new DirectoryIterator(get_template_directory() . '/images/headers/'); 
echo $dir; 

Answer 2

看起来你传递一个网址，而不是一个路径：

DirectoryIterator->__construct('http://oberperf...') 

您应该通过目录构造的完整本地路径名。
