关于$_SESSION['verify']的迷惑
为什么表单提交之后session的值会是post传过去的值呢?
换个名字都可以正常,唯独用verify会出现这种现象

这很可能是PHP的一个Bug。
因为$_SESSION
中的变量保存使用的是引用,当register_globals
设置为on
的时候,如果全局变量中有名字和$_SESSION
中的变量名一样(比如你的代码中的$verify
变量和$_SESSION['verity']
这两个verify
),PHP会有不可预料的行为发生。所以,你的这个问题不是POST过去的值传到了$_SESSION
中,而是$_SESSION['verify']
错误地引用了全局的$verify
变量。
这在PHP的官方文档下用户的Comment中提到多次:

Post 的值是从表单传过去的
