You have already include a database.php file where class Database is already declared. –Neeraj Kumar Apr 14 '14 at 11:23 add a comment| 3 Answers 3 active oldest votes up vote 5 down vote You include 2 files in a single "run". Think of it like this: All the included files are put together by PHP to create one big script. Every include or require fetches a file, and pastes its content in that one big script. The two files you are including, both require the same file, which declares the Database class. This means that the big script that PHP generates looks like this: class Message {} class Database {}//required by message.php class User {} class Database {}//required by user.php As you can see class Database is declared twice, hence the error. For now, a quick fix can be replacing the require('database.php'); statements with: require_once 'database.php'; Which checks if that particular file hasn't been included/required before. If it has been included/required before, PHP won't require it again. A more definitive and, IMHO, better solution would be to register an autoloader function/class method, and let that code take care of business. More on how to r

My cannot redeclare class code is. index.php login($username, $password); } ?> class.users.php mysqli->prepare("SELECT username, password FROM users WHERE username = ? AND password = ? LIMIT 1"); $stmt->bind_param('ss', $username, $password); $stmt->execute(); $stmt->bind_result($username, $password); $stmt->store_result(); if($stmt->num_rows == 1) { while($stmt->fetch()) { $_SESSION['username'] == $username; header("Location: dashboard.php"); } } else { return false; } $stmt->close(); $stmt->free_result(); } } $users = new users(); ?> connect.php mysqli = new mysqli($host, $user, $pass, $name); } } ?> The class Database isn't called twice? so how is it a error? can anyone explain why in the comments. php mysql share|improve this question edited Sep 2 '14 at 22:33 asked Sep 2 '14 at 22:28
