Once we create an object, we can access its properties.

We reference the object name, followed by the characters dash and

greater than, which together make a single arrow.

And finally, the property name.

Note that the property name does not start with the dollar sign.

Only the object name starts with the dollar sign,

because this entire reference is one variable.

Because multiple instances or

objects of a class can exist if the individual object is not referenced,

the script would be unable to determine which object to read from.

We can then interact with this property just like we would any other variable.

To display this property, we can type echo before it.

To set the property, we use the object.

The single arrow, the property name, the equal sign, and then our value.

Let's print this property again.

Now let's check this out in our console.

We now see Alina Holligan, Grandma Holligan.

The power of OOP becomes apparent

when using multiple instances of the same class.

More than one object can be built from the same class at the same time,

each one independent of the others.

Let's create a second object.

We'll name this recipe2.

We can then set the source for recipe2.

Now let's print the source for both recipe1 and recipe2.

Now let's run the script in the console.

$recipe1->source was first initialized with the default value Alena Holligan.

We then changed that value to Grandma Holligan.

Then we created a second recipe and set its source to Betty Crocker.

This had no effect on recipe1, because recipe1 and recipe2 are separate entities.

This makes for

easy separation of different pieces of code into small related bundles.

Great job.

We set up our recipe class to contain all the properties of a recipe object, and

we demonstrated how we can create individual objects that exist

independently of other objects and can have their own property values.

Next, we want to set up the actions our object will perform.
