“检查PHP $ _SESSION为空”问题 [英] "Check PHP $_SESSION empty" problem
问题描述
大家好,有人可以向我解释这段代码有什么不对吗? ...(见图片代码或查看下方)
当我运行脚本应检查会话变量是否为空,如果是,则为其赋值。
下次脚本运行时(在同一页面会话中),
那么会话变量将不是空的意味着if语句不应该运行。
问题是无论会话变量是否具有值,它总是运行。
主脚本:
我开始删除counter.php中的第1行。

Hi all could someone please explain to me whats wrong with this code?...(see image for code or check bellow)
When I run the script it should check if the session variable is empty, if it is then give it a value.
The next time the script runs (in the same page session),
then the session variable will ofcourse not be empty meaning that the if statement should not run.
The problem is that is always runs no matter if the session variable has a value or not.
Main Script:
I''d start with deleting line #1 in counter.php.
