致命错误：找不到类__

Question

Last spring I was working on a project using PHP, and it was working well. I had no time to work on it later, but now after I changed hosting I want to work on it again. I send files in working directory, but the error appears. It says that can't find Class TemplateLogin in class Login

Login.php:

class Login extends TemplateLogin

TemplateLogin.php:

abstract class TemplateLogin extends Core

Login.php and TemplateLogin.php are in the same folder

Answer 1

Your file Login.php needs to require or include the file TemplateLogin.php:

require_once 'TemplateLogin.php';

Or php will not know how the class TemplateLogin is defined.

An alternative to manually including/requiring every file is to define an autoloading function .
