//Connect to the database $conn = mysqli_connect($host, $username, $password, $db_name); //Get the number of users in the database $sql = "SELECT COUNT(*) as total FROM users"; $result = mysqli_query($conn, $sql); $row = mysqli_fetch_assoc($result); //Output the results echo "Total number of users: " . $row['total'];
//Read the user data from a file $file = file_get_contents('users.txt'); $users = explode("\n", $file); //Count the number of users $num_users = count($users); //Output the results echo "Total number of users: " . $num_users;In this example, the app reads user data from a file, counts the number of users, and outputs the result. Based on the examples given, the User Count app likely belongs to the database or file I/O package library in PHP.
