Web サイト用のユーザー アカウント システムを作成していますが、 include 'core/init.php';
関数を使用するとエラーが発生します。私は初心者で、ただ学んでいるので、これは本当に簡単なことかもしれません。
Fatal error: Cannot redeclare user_data() (previously declared in C:\xampp\htdocs\PatchMyPC\core\functions\users.php:3) in C:\xampp\htdocs\PatchMyPC\core\functions\users.php on line 17
これが私のusers.phpおよびinit.phpファイルのコードです
init.php
