What is the best practice for dynamically loading a database table based on user selection in PHP?

When dynamically loading a database table based on user selection in PHP, it is best to use prepared statements to prevent SQL injection attacks. You can achieve this by using PHP's PDO (PHP Data Objects) extension. By dynamically constructing the SQL query based on the user's input and binding parameters to the prepared statement, you can ensure that the query is secure and efficient. 

// Assuming $userSelection contains the user's input
$userSelection = $_POST['userSelection'];

// Connect to the database using PDO
$pdo = new PDO('mysql:host=localhost;dbname=your_database', 'username', 'password');

// Prepare a SQL query based on the user's selection
$stmt = $pdo->prepare("SELECT * FROM your_table WHERE column_name = :userSelection");

// Bind the user's selection to the prepared statement
$stmt->bindParam(':userSelection', $userSelection);

// Execute the query
$stmt->execute();

// Fetch the results
$results = $stmt->fetchAll();

// Loop through the results and do something with them
foreach ($results as $row) {
    // Do something with each row
}
