Definition: Database changes.php: PHP script handling database queries for security, system integrity checks.
Definition: A PHP script used in an online database management system to query, update, or alter data stored in a MySQL database (or other types of databases) without directly accessing it from client-side code. The process involves transforming the current state of the database into the expected output based on user inputs and queries made through HTTP requests.
Example usage:
```
update_user('name', 'new_name');
// more operations here for user update or deletion...
}
$db = new Database(); // create database object
$db->query("SELECT
FROM users");
```
This script updates the 'users' table in a MySQL database to add a new record.
