唠叨帮忙看看这个代码在PHP5上怎么提示错误 在PHP4上运行正常

真不想麻烦你了 但是我搞了老半天 一点头续都没有 老说什么数组错误

你是如何调用的

[an9ryfr09]

你是不是调用的时候传值错误？这个类本身没有语法错误

[haihaiff]

<?php
include "treemenu.inc";
$tree = new treemenu("a");
$tree->addNode(1, "grANDpa");
$tree->addNode(2, "pa");
$tree->addNode(3, "son");
$tree->addNode(2, "uncle");
$tree->loadTreeFROMFile("demomenu.txt");

$tree->show();
?>
就是这样调用的啊

[haihaiff]

我知道我不应该发那么长的贴子 但是等了老半天也灭有人回答 叫我删贴也不是 给分也不是
NND

[an9ryfr09]

我这里得到的只是notice和warning。
你在程序顶部加入ini_set('display_errors','off');试试看能否运行
