根因分析

PHP 的 use 语句被误解为 trait 上下文，通常是因为开发者在类体内错误地写了 'use App\Models\User;' 而不是继承它，或者该类未声明为 trait。

English

PHP's use statement is misinterpreted when a class name is used in a trait context, typically because the developer accidentally wrote 'use App\Models\User;' inside a class body instead of extending it, or the class is not declared as a trait.

解决方案

  1. Replace 'use App\Models\User;' inside the class body with 'class Admin extends \App\Models\User' to properly inherit from the class.
  2. If the intent is to use a trait, ensure the source file defines a trait (e.g., 'trait User { }') and then use 'use User;' inside the class.
  3. Check for typos: verify that the class file at src/Models/User.php declares 'class User' not 'trait User' or 'interface User'.

无效尝试

常见但无效的做法:

  1. 85% 失败

    Adding a 'use' statement at the top of the file for the class does not fix the error because the problem is the misuse of 'use' inside the class body to import a class, not a trait.

  2. 60% 失败

    Renaming the class to a trait by adding 'trait User { }' works but changes the design incorrectly; the class should be extended with 'extends'.
