What are the advantages of using Query Builders like DBAL or Aura.SQL for dynamically constructing SQL queries in PHP, compared to manually concatenating strings?

Using Query Builders like DBAL or Aura.SQL in PHP provides several advantages over manually concatenating strings to construct SQL queries. These tools help prevent SQL injection attacks by automatically escaping input values, provide a cleaner and more readable syntax for building queries, and offer a more secure and reliable way to interact with databases. Additionally, Query Builders abstract away the specific syntax of different database systems, making it easier to switch between databases without needing to rewrite all SQL queries. 

// Example of using DBAL to dynamically construct an SQL query
use Doctrine\DBAL\DriverManager;

// Create a connection to the database
$connectionParams = array(
    'dbname' => 'my_database',
    'user' => 'my_user',
    'password' => 'my_password',
    'host' => 'localhost',
    'driver' => 'pdo_mysql',
);
$conn = DriverManager::getConnection($connectionParams);

// Use DBAL to build a SELECT query
$queryBuilder = $conn->createQueryBuilder();
$query = $queryBuilder
    ->select('*')
    ->from('my_table')
    ->where('column = :value')
    ->setParameter('value', $inputValue)
    ->execute();

// Loop through the results
while ($row = $query->fetch()) {
    // Process the results
}
