【问题描述】：
在他通过表单登录后，我正在努力根据他的 ID 或电子邮件来获取用户。该函数在 User.class.php 中定义，我想在另一个名为 profile.php 的 php 文件上调用它，但它继续给我语法错误，我不知道如何修复它..
错误： 已弃用：不应静态调用非静态方法 User::getUserId() 注意：未定义变量：电子邮件在
使用 getter 和 setter、函数使用户类变得干净
下面是 Profile.php 和用户类代码：
<?php
include_once("classes/User.class.php");
include_once("classes/db.class.php");
try {
$conn = Db::getInstance();
$user = User::getUserId($email);
} catch (PDOException $e) {
die("Could not connect to the database $dbname :" . $e->getMessage());
}
?>

-
在调用
getUserId()方法之前，您需要从User类中实例化一个对象，因为该方法尚未被声明为静态...又名$user = User::getUserId($email);很无聊。 -
它不是静态方法。您的代码也对 SQL 注入开放
-
错误很明显，您的函数
getUserId不是静态的，但它被静态调用（User::getUserId(...)）。
