How can assigning aliases in PHP queries help in avoiding errors and improving code readability?

Assigning aliases in PHP queries can help in avoiding errors and improving code readability by giving more descriptive names to the columns returned in the query result. This can make it easier to understand the data being retrieved and used in the code, especially when working with complex queries or joining multiple tables. 

// Example query with aliases for improved readability
$query = "SELECT users.id AS user_id, users.name AS user_name, orders.total AS order_total FROM users JOIN orders ON users.id = orders.user_id";
$result = mysqli_query($connection, $query);

// Loop through the query result and access columns by their aliases
while ($row = mysqli_fetch_assoc($result)) {
    echo "User ID: " . $row['user_id'] . ", User Name: " . $row['user_name'] . ", Order Total: " . $row['order_total'] . "<br>";
}
