What is the issue with loading a database table based on user selection in PHP?

When loading a database table based on user selection in PHP, the main issue is ensuring that the user input is sanitized to prevent SQL injection attacks. One way to solve this issue is by using prepared statements with parameterized queries to securely interact with the database. 

// Assuming $userSelection contains the user input for selecting a specific table
$userSelection = $_POST['user_selection'];

// Establish a database connection
$pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");

// Prepare a parameterized query to select data from the specified table
$stmt = $pdo->prepare("SELECT * FROM $userSelection");
$stmt->execute();

// Fetch the results and display them
while ($row = $stmt->fetch()) {
    echo $row['column_name'] . "<br>";
}
