1
00:00:00,940 --> 00:00:05,122
Once we create an object,
we can access its properties.

2
00:00:05,122 --> 00:00:11,220
We reference the object name,
followed by the characters dash and

3
00:00:11,220 --> 00:00:14,540
greater than,
which together make a single arrow.

4
00:00:14,540 --> 00:00:16,260
And finally, the property name.

5
00:00:18,610 --> 00:00:22,630
Note that the property name does
not start with the dollar sign.

6
00:00:22,630 --> 00:00:26,110
Only the object name starts
with the dollar sign,

7
00:00:26,110 --> 00:00:29,930
because this entire
reference is one variable.

8
00:00:29,930 --> 00:00:31,950
Because multiple instances or

9
00:00:31,950 --> 00:00:37,230
objects of a class can exist if
the individual object is not referenced,

10
00:00:37,230 --> 00:00:41,240
the script would be unable to
determine which object to read from.

11
00:00:42,310 --> 00:00:47,330
We can then interact with this property
just like we would any other variable.

12
00:00:47,330 --> 00:00:50,641
To display this property,
we can type echo before it.

13
00:00:52,195 --> 00:00:55,331
To set the property, we use the object.

14
00:00:57,997 --> 00:01:04,620
The single arrow, the property name,
the equal sign, and then our value.

15
00:01:09,920 --> 00:01:11,533
Let's print this property again.

16
00:01:17,854 --> 00:01:20,105
Now let's check this out in our console.

17
00:01:24,567 --> 00:01:28,238
We now see Alena Holligan,
Grandma Holligan.

18
00:01:28,238 --> 00:01:31,290
The power of OOP becomes apparent

19
00:01:31,290 --> 00:01:35,060
when using multiple
instances of the same class.

20
00:01:35,060 --> 00:01:40,830
More than one object can be built
from the same class at the same time,

21
00:01:40,830 --> 00:01:44,180
each one independent of the others.

22
00:01:44,180 --> 00:01:45,770
Let's create a second object.

23
00:01:47,718 --> 00:01:49,500
We'll name this recipe2.

24
00:01:55,654 --> 00:01:59,025
We can then set the source for recipe2.

25
00:02:06,355 --> 00:02:10,333
Now let's print the source for
both recipe1 and recipe2.

26
00:02:21,214 --> 00:02:23,360
Now let's run the script in the console.

27
00:02:25,655 --> 00:02:31,710
$recipe1->source was first initialized
with the default value Alena Holligan.

28
00:02:31,710 --> 00:02:35,410
We then changed that value
to Grandma Holligan.

29
00:02:35,410 --> 00:02:40,850
Then we created a second recipe and
set its source to Betty Crocker.

30
00:02:40,850 --> 00:02:48,140
This had no effect on recipe1, because
recipe1 and recipe2 are separate entities.

31
00:02:48,140 --> 00:02:48,970
This makes for

32
00:02:48,970 --> 00:02:53,760
easy separation of different pieces
of code into small related bundles.

33
00:02:54,870 --> 00:02:55,760
Great job.

34
00:02:55,760 --> 00:03:00,850
We set up our recipe class to contain all
the properties of a recipe object, and

35
00:03:00,850 --> 00:03:04,960
we demonstrated how we can create
individual objects that exist

36
00:03:04,960 --> 00:03:10,490
independently of other objects and
can have their own property values.

37
00:03:10,490 --> 00:03:13,970
Next, we want to set up the actions
our object will perform.
