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
  • 0:03

    We'll call this getIngredients.

  • 0:10

    From this method I return this ingredients.

  • 0:17

    I think we're ready to clean up our object instantiation and output and

  • 0:20

    move it out of our class file.

  • 0:23

    So let's remove everything from this file.

  • 0:26

    Select all and cut, and then we'll create a new file.

  • 0:32

    We'll call it cookbook.php.

  • 0:37

    We can paste this code into cookbook.php.

  • 0:41

    At the beginning of the file, we need to open our php, and then we

  • 0:46

    need to include recipes.php.

  • 0:50

    But we also need to add the folder classes.

  • 0:59

    Great, let's save these files.

  • 1:03

    Now in our console, we run php cookbook.php.

  • 1:11

    And great, we return the same output.

  • 1:14

    Let's clean up this output and then add some ingredients to recipe one.

  • 1:36

    Now let's loop through our ingredients, after we get the title.

  • 1:48

    We'll set each of our ingredients to an array called ing for ingredient.

  • 1:58

    Then we can echo out a new line for each item.

  • 2:04

    Then we'll call the amount, like two

  • 2:12

    and then our measurement but we also want to space in between so,

  • 2:17

    two cups.

  • 2:24

    And then we want the item, again, another space.

  • 2:35

    Great, let's run our code.

  • 2:38

    We see My First Recipe, 1 Egg, 2 cup Flour.

  • 2:43

    Good job, that was quite a few pieces to put together, but

  • 2:46

    you should have a pretty good idea of the usefulness of getters and setters now.

  • 2:51

    We have the most complicated property out of the way.

  • 2:54

    So we're ready to breeze through the rest of these properties in the next video.
