Deprecated: Function session_register() is deprecated in C:\xampp\htdocs\mysite\forum part two\login.php on line 63

第62行和第63行的代码分别如下所示

session_register("password", $password);

Answer 1

来自docs：

<?php
// Use of session_register() is deprecated
$barney = "A big purple dinosaur.";
session_register("barney");

// Use of $_SESSION is preferred, as of PHP 4.1.0
$_SESSION["zim"] = "An invader from another planet.";

Answer 2

请改用超级全球$_SESSION。

$_SESSION['username'] = $username;

Answer 3

在将任何内容输出到浏览器并将行替换为：

之前，将session_start();放在脚本/页面的最顶部

$_SESSION['username'] = $username;
$_SESSION['password'] = $password;

Answer 4

$_SESSION['username'] = &$username;

为了复制您需要存储变量引用的功能。
