函数 startElement、endElement、cdata  未给出，不好说什么
$listtags = explode(" ", "list data attach user");function startElement($parser, $name, $attrs) {
global $depth, $curpath, $config, $havedata, $listtags; array_push($curpath, strtolower($name)); $ptr =& $config;
foreach ($curpath as $path) {
$ptr =& $ptr[$path];
} /* is it an element that belongs to a list? */
if (in_array(strtolower($name), $listtags)) {
/* is there an array already? */
if (!is_array($ptr)) {
/* make an array */
$ptr = array();
} array_push($curpath, count($ptr)); } else if (isset($ptr)) {
/* multiple entries not allowed for this element, bail out
* 不允许元素多次出境，否则溢出*/
//die(sprintf("XML error: %s at line %d cannot occur more than once \n",
die(sprintf("XML error: %s 在第 %d 行，超过一次就不再出现\n",
$name,
xml_get_current_line_number($parser)));
} $depth++;
$havedata = $depth;
}function endElement($parser, $name) {
global $depth, $curpath, $config, $havedata, $listtags; if ($havedata == $depth) {
$ptr =& $config;
foreach ($curpath as $path) {
$ptr =& $ptr[$path];
}
$ptr = "";
} array_pop($curpath); if (in_array(strtolower($name), $listtags))
array_pop($curpath); $depth--;
}function cData($parser, $data) {
global $depth, $curpath, $config, $havedata; $data = trim($data, "\t\n\r"); if ($data != "") {
$ptr =& $config;
foreach ($curpath as $path) {
$ptr =& $ptr[$path];
} if (is_string($ptr)) {
$ptr .= $data;
} else {
if (trim($data, " ") != "") {
$ptr = $data;
$havedata++;
}
}
}
}续解……
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？
你到底要的是什么Array

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] => <[email protected]>
            [delivered-to] => [email protected]……
         )
)
Array
(
    [0] => Array
        (
            [return-path] => <[email protected]>
            [delivered-to] => [email protected]……
         )
    [1] => Array
        (
            [return-path] => <[email protected]>
            [delivered-to] => [email protected]……
         )
)我那里写错了吗？
真的吗？我的怎么会不一样呢？能把您的php调用那段代码贴来看看吗？我想比较一下哪错了，已经找了很久了，一直是出现数组递归……

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！
