What are the key considerations when designing a PHP/MySQL database for displaying tabular data on a website?

When designing a PHP/MySQL database for displaying tabular data on a website, key considerations include defining appropriate table structures, establishing relationships between tables using foreign keys, optimizing queries for efficient data retrieval, and implementing proper security measures to prevent SQL injection attacks. 

// Example of creating a MySQL table for tabular data
CREATE TABLE users (
    id INT AUTO_INCREMENT PRIMARY KEY,
    username VARCHAR(50) NOT NULL,
    email VARCHAR(100) NOT NULL,
    password VARCHAR(255) NOT NULL
);

// Example of querying the database to display tabular data
$query = "SELECT * FROM users";
$result = mysqli_query($connection, $query);

if (mysqli_num_rows($result) > 0) {
    echo "<table>";
    while ($row = mysqli_fetch_assoc($result)) {
        echo "<tr>";
        echo "<td>" . $row['id'] . "</td>";
        echo "<td>" . $row['username'] . "</td>";
        echo "<td>" . $row['email'] . "</td>";
        echo "</tr>";
    }
    echo "</table>";
} else {
    echo "No users found";
}
