无论我做什么，PHP都会将变量设置为数组？

这是我遇到过的最奇怪的错误，我在这里束手无策。它只是从脚本开始的，我知道我唯一改变的是在名字和姓氏变量上运行大写函数

问题在于$lname变量。我将脚本设置为debug，并在每个进程中回显$lname，只有在将其设置为_SESSION变量后，它才会更改为数组。我所做的一切似乎都不管用。每次用户返回表单时，它都会取消设置所有会话变量，但我甚至尝试更改$u会话['reglname']的名称；我还是会有同样的事情发生

我在这里束手无策，如果你通读这篇文章，你会发现我已经尽了一切努力，把它作为一根绳子穿过去。我想我可以编辑后续的脚本来解释它是一个数组，但是我更想弄清楚这里到底发生了什么，这样我以后就可以避免它了！请帮忙

这是你的问题：

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

我想你想要：

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

Ereg将在参数3中存储匹配项。

提示：在问题文本中使用一些段落分隔符。@Jared+1以满足您的请求。这是非常有用的，比如将代码分解为模块，以便更容易处理。Lol这里是var_dump$\会话['reglname']：Arraystring5 Arraydon别忘了接受答案。顺便说一句，ereg已被弃用：擦擦它，我以为它在工作。当我扔掉它的时候，我得到了这个信息：string5 Doe，如果输入的名字是John Doe。这是值得的+一个耐心地涉过所有这些。@Jacob-这是一个byVal。它返回字符串的长度和匹配项。因此，它使用了C样式的引用。当我考虑它的时候，你可能需要添加一个参考捕手如果！ereg[a-zA-Z]+，$fname.$lname，$tmpArr，否则函数可能会返回true。意大利面条代码的插图Jacob的代码。另外，替换$year=dateY；其中$year=日期'Y'；尽量不要使用ereg，因为它已被弃用。
