How can PHP be used to automatically store the name of a user who is logged in when submitting an entry to a database?

To automatically store the name of a logged-in user when submitting an entry to a database, you can first retrieve the username of the logged-in user from the session data. Then, use this username to insert into the database along with the other entry details. 

// Retrieve the logged-in user's name from session data
$loggedInUser = $_SESSION['username'];

// Connect to the database
$connection = new mysqli("localhost", "username", "password", "database");

// Prepare the SQL query to insert the entry along with the user's name
$query = "INSERT INTO entries (username, entry_content) VALUES ('$loggedInUser', 'Entry content goes here')";

// Execute the query
$connection->query($query);

// Close the database connection
$connection->close();
