How can using aliases in SQL queries improve the accuracy and readability of PHP code when working with database queries?

Using aliases in SQL queries can improve the accuracy and readability of PHP code by providing more descriptive names for columns or tables, making it easier to understand the query logic. Aliases can also help avoid naming conflicts when joining multiple tables or selecting data from multiple sources. This can lead to more efficient and maintainable code in PHP when working with database queries. 

$query = "SELECT u.id AS user_id, u.name AS user_name, p.title AS post_title 
          FROM users u 
          JOIN posts p ON u.id = p.user_id 
          WHERE u.status = 'active'";
$result = mysqli_query($connection, $query);

if ($result) {
    while ($row = mysqli_fetch_assoc($result)) {
        echo $row['user_id'] . ' - ' . $row['user_name'] . ' - ' . $row['post_title'] . '<br>';
    }
} else {
    echo "Error: " . mysqli_error($connection);
}
