我遇到了这个问题......它说“意外的T_VARIABLE”。有问题的行是这样的：
$children[ $i['parent_id'] ][] = array($i['forum_id'], "<option value=\"{$i['forum_id']}\"$selected> ", "{$i['forum_name']}</option>\n");
我尝试删除$(in $children)，但仍然导致错误。它说“解析错误：语法错误，意外的'['在......”
奇怪的是，这在 PHP 5.2 中没有问题。但在 PHP 5.3 中，问题出现了。
由于我不是真正的程序员（只知道一点基础，我主要是设计），所以我对这里发生的事情一无所知。有人可以提供帮助吗？
