What are some potential pitfalls when creating buttons dynamically in PHP based on database entries?

One potential pitfall when creating buttons dynamically in PHP based on database entries is not properly sanitizing the data retrieved from the database, which can lead to security vulnerabilities such as SQL injection. To solve this issue, it is important to always sanitize the data before using it to generate the buttons. 

// Retrieve data from the database
$query = "SELECT button_text, button_link FROM buttons_table";
$result = mysqli_query($connection, $query);

// Create buttons dynamically
while($row = mysqli_fetch_assoc($result)) {
    $button_text = htmlspecialchars($row['button_text']);
    $button_link = htmlspecialchars($row['button_link']);
    
    echo "<a href='$button_link'><button>$button_text</button></a>";
}
