Cleaning Up the Class

2:58 with Alena Holligan

Let’s clean up our object instantiation and output and move it out of our class file. Our cookbook will use more than one class so this is a great point to start separating the concerns.

Challenges

Now that we've seen how to get and set an associative array, try adding some new methods around ingredients. Such as:

  1. Converted to a simple array of ingredient strings
  2. Converted to just a string of ingredient items
  3. Return the ingredients formatted in a list

    We'll call this getIngredients. 0:03
    From this method I return this ingredients. 0:10
    I think we're ready to clean up our object instantiation and output and 0:17
    move it out of our class file. 0:20
    So let's remove everything from this file. 0:23
    Select all and cut, and then we'll create a new file. 0:26
    We'll call it cookbook.php. 0:32
    We can paste this code into cookbook.php. 0:37
    At the beginning of the file, we need to open our php, and then we 0:41
    need to include recipes.php. 0:46
    But we also need to add the folder classes. 0:50
    Great, let's save these files. 0:59
    Now in our console, we run php cookbook.php. 1:03
    And great, we return the same output. 1:11
    Let's clean up this output and then add some ingredients to recipe one. 1:14
    Now let's loop through our ingredients, after we get the title. 1:36
    We'll set each of our ingredients to an array called ing for ingredient. 1:48
    Then we can echo out a new line for each item. 1:58
    Then we'll call the amount, like two 2:04
    and then our measurement but we also want to space in between so, 2:12
    two cups. 2:17
    And then we want the item, again, another space. 2:24
    Great, let's run our code. 2:35
    We see My First Recipe, 1 Egg, 2 cup Flour. 2:38
    Good job, that was quite a few pieces to put together, but 2:43
    you should have a pretty good idea of the usefulness of getters and setters now. 2:46
    We have the most complicated property out of the way. 2:51
    So we're ready to breeze through the rest of these properties in the next video. 2:54
