A Select Statement that would do the following

I am just learning how to wrap my head around sql and php. I have 4 tables structured as follows

+-----------+    +------------+    +---------+    +----------+
|  Project  |    | Slide      |    | Shape   |    |  Points  |
+-----------+    +------------+    +---------+    +----------+
|    id     |    |  id        |    | id      |    | id       |
+-----------+    | project_id |    | cont_id |    | shape_id |
                 +------------+    +---------+    | x        |
                                                  | y        |
                                                  +----------+

As you can see the tables are linked by id all the way down to points meaning a project will contain a number of slides that contain a number of shapes that contain a number of points.

I have a SQL query

SELECT slide.`id`, shape.`id`, points.`x_point`, points.`y_point` 
FROM `project`, `slide`, `shape`, `points` 
WHERE 1 = slide.`project_id` 
   AND slide.`id` = shape.`slide_id` 
   AND shape.`id` = points.`shape_id`

What I want is to take the results of this query that look like this

[0] => stdClass Object
     (
         [id] => 27
         [x] => 177
         [y] => 177
     )

 [1] => stdClass Object
     (
         [id] => 27
         [x] => 178
         [y] => 423
     )

 [2] => stdClass Object
     (
         [id] => 27
         [x] => 178
         [y] => 419
     )

 [3] => stdClass Object
     (
         [id] => 27
         [x] => 178
         [y] => 413
     )

 [4] => stdClass Object
     (
         [id] => 27
         [x] => 181
         [y] => 399
     )

 [5] => stdClass Object
     (
         [id] => 27
         [x] => 195
         [y] => 387
     )

 [6] => stdClass Object
     (
         [id] => 27
         [x] => 210
         [y] => 381
     )

 [7] => stdClass Object
