Question

此if语句已被弃用

if(!session_is_registered('firstname')){ 
header("location: index.php"); // << makes the script send them to any page we set
} else {
print "<h2>Could not log you out, sorry the system encountered an error.</h2>";
exit();
}

我用

替换了它

if ( isset( $_SESSION['firstname'] ) ){
header("location: index.php"); // << makes the script send them to any page we set
} else {
print "<h2>Could not log you out, sorry the system encountered an error.</h2>";
exit();

初始代码附加到我的logout.php脚本中。当我转到链接logout.php时，会显示“无法将您注销，抱歉系统遇到错误。”

这是正确的解决方案，因为我对代码没有问题

Answer 1

根据您的第一个片段，我认为您的逻辑失败。

尝试：

if ( !isset($_SESSION['firstname']) ){
    header("location: index.php"); // << makes the script send them to any page we set
} else {
    exit('<h2>Could not log you out, sorry the system encountered an error.</h2>');
}

Answer 2

你有session_start（）;在你的页面上？

PHP --- if（！session_is_registered已弃用？
