为什么返回的数组$mail_list会是递归出现的？xml解析是正确的啊，要不然也不会解出数组了。但是哪出问题了呢？

真的非常感谢您的帮助，我把parse_xml_config()放到循环里了，所以才一直出现递归数组。
不愧是PHP中的巨擘！
以后要多向您学习了！

咦？你这个数组怎么出来的？我要的就是这个数组啊，但是我写了一个print_r($mail_list)打出来的数组，却是两个啊。


Array

(

    [0] => Array

        (

            [return-path] => <anonymous@214.netchina.com.cn>

            [delivered-to] => yushuai.niu@214.netchina.com.cn……

         )

)

Array

(

    [0] => Array

        (

            [return-path] => <anonymous@214.netchina.com.cn>

         )

    [1] => Array

我只想得到：count-->>2的那个数组，正常情况应该是array([0]=>1,[1]=>2,[2]=>3)
但是，我只print_r()，它返回的是
array([0]=>1)
array([0]=>1,[1]=>2)
array([0]=>1,[1]=>2,[2]=>3)
这是什么情况呢？第一次见，应该怎么取到最后那个数组呢？这样子描述不知清楚否？
