在php中创建和使用多维数组

Question

         $breakfast = array(
                               'rest_id' => $rest_id  ,
                               'type' => 'Breakfast' ,
                               'value' => $bprice  
                                );



            $lunch = array(
                               'rest_id' => $rest_id  ,
                               'type' => 'Facilities' ,
                               'value' => $lprice  
                                );


            $dinner = array(
                               'rest_id' => $rest_id  ,
                               'type' => 'Facilities' ,
                               'value' => $dprice  
                                );

            $data = $breakfast . $lunch . $dinner;

Is the way i created the array $data correct? If yes... now how do i get the array breakfast inside it, if i want to pass it to one function?

I want to do something like this:

$this->db->insert_breakfast($breakfast);

So how do i get breakfast array out of $data now?

Answer 1

If you want $breakfast , $lunch and $dinner to make a multi-dimensional array in $data , you will need to replace your assignment with the following.

$data = array('breakfast' => $breakfast, 'lunch' => $lunch, 'dinner' => $dinner);

Then you can access any of them like $data['breakfast']['value'] .

I didn't quite understand the DB part. Comment back and I'd be glad to help.

Answer 2

The correct is

$data = array($breakfast, $lunch, $dinner);

The . operator means string concatenation. You can access $breakfast with $data[0] , since it's the first member. You can also use associative arrays; see @Jason's answer.
