无论我做什么，PHP都会为数组设置一个变量？

Question

这是我遇到过的最奇怪的错误，我在这里结束了。它只是从脚本开始，甚至知道我改变的唯一一件事是在名字和姓氏变量上运行大写函数。

问题出在“$ lname”变量。我已经在调试中获得脚本，并且在每个进程中都会回显“$ lname”，并且只有在将它设置为_SESSION变量后才会变为数组。我做的没有任何事情似乎有效。每次用户返回表单时，它都会取消所有会话变量，但我甚至尝试更改“$ _SESSION ['reglname']”的名称;而且我仍然会发生同样的情况。智慧在这里结束了，如果你通读了这篇文章，你会发现我已经尝试过所有的东西来强制它作为一个字符串。我想我可以编辑后续的脚本来说明它是一个数组，但我宁愿图！出了地狱去什么在这里，所以我能避免它在未来请帮助

这是你的问题：

if(!ereg("[a-zA-Z]+", $fname, $lname)){ 

我想你想：

if(!ereg("[a-zA-Z]+", $fname.$lname)){ 

EREG的将存储的比赛在参数3.
