What are the best practices for structuring PHP code to improve readability and maintainability, especially when using Fluent Interface design patterns?

When using Fluent Interface design patterns in PHP, it's important to structure your code in a way that enhances readability and maintainability. One way to achieve this is by breaking down complex method chaining into smaller, more manageable chunks. This can be done by using meaningful method names, avoiding excessive chaining, and organizing your code logically. 

class QueryBuilder
{
    protected $query;

    public function __construct()
    {
        $this->query = '';
    }

    public function select($columns)
    {
        $this->query .= "SELECT $columns ";
        return $this;
    }

    public function from($table)
    {
        $this->query .= "FROM $table ";
        return $this;
    }

    public function where($condition)
    {
        $this->query .= "WHERE $condition ";
        return $this;
    }

    public function getQuery()
    {
        return $this->query;
    }
}

$query = new QueryBuilder();
$query->select('name, email')
      ->from('users')
      ->where('id = 1');

echo $query->getQuery();
