Are prepared statements alone sufficient to protect against SQL injection when dealing with dynamic table names in PHP?

Prepared statements alone are not sufficient to protect against SQL injection when dealing with dynamic table names in PHP. To properly secure dynamic table names, you should use whitelisting or blacklisting to validate the table name before constructing the query. 

// Example of using whitelisting to validate dynamic table names
$allowed_tables = ['table1', 'table2', 'table3'];
$table_name = $_GET['table'];

if (in_array($table_name, $allowed_tables)) {
    $stmt = $pdo->prepare("SELECT * FROM $table_name WHERE column = :value");
    $stmt->bindParam(':value', $value);
    $stmt->execute();
} else {
    echo "Invalid table name";
}
