$/*09$: Use the set$\_$species method on each pet

instance from above.

$-$ $pet$1$ is a "Cow"

$-$ $pet$2$ is a "Dog"

$-$ $pet$3$ is a "Duck"

Afterwards, create a $petArray that contains

all $3$ pet instances.

Loop through the array in reverse order

and output the name value for each pet

object in the array in a list item nested

inside of the list item with id of $9.$

Not sure about the reverse?

Look at the PHP docs.
