因此无法开始将其同时转移到同一项目的另一个文件夹中
编码限制就像这样

现在我的问题是我在犯错误的地方...... ???? 因为我已经设置了会话以及获取它也因此没有放出.... !!!!!
我想在logout.php
中销毁我的会话<?php
session_destroy();
unset($_SESSION["admin"]);
$target = "admin.php";
header( 'Location: ' . $target ) ;
?>
因此会议没有破坏
答案 0 :(得分：2)
要使用基于cookie的会话，必须在向浏览器输出任何内容之前调用session_start（）。
答案 1 :(得分：0)
如果您的php文件没有相互链接（例如MVC结构），则必须在每个文件中声明session_start()
答案 2 :(得分：0)
您没有在$ _SESSION ['login']中设置任何内容。你只需要$ _SESSION ['admin'] ='log_in'。 如此处所述，无论您想要使用会话（从会话中设置或获取值），您都需要在访问$ _SESSION []之前使用session_start（）函数。
