两个表连接两个结果

Question

I have a two tables one with blog news and another with articles. Simply what i need to do is join them so i have code like this

$query = $this->db->select('*')
              ->from('blogs')
          ->select('blogs.id as BlogId....')
      ->join('articles', 'articles.highlight = 1', 'left')
      ->join('authors', 'articles.author = authors.id', 'left')
      ->join('companies', 'authors.company_id = companies.id')
      ->get();

Join is working ok but then i need to do echo for data in foreach and here my problem comes. I have duplicated blogs under articles. So if i have 5articles under every is blog post(i have only one). Is there any possible way to show only one blog and then articles?

Thanks

Most people will tell you to foreach over your outer table, but that is terrible. Try using the Underscore library http://brianhaveri.github.com/Underscore.php/#groupBy on your result array, as I show here:
