You need to add a PHP block first, Dolphin don't have it as default so you need to add this first.

You can use @newdreamers code to do it

or you use @jtadeo code to do it
http://www.boonex.com/unity/blog/entry/How_to_Add_PHP_in_a_BLOCK

If you are a bit comfortable with edit some PHP code and use phpMyAdmin I would have used @newdreamers way to do it.(Very easy to add a new PHP block later)
--------------------

When see more you have added @newdreamers code/change,
then you can add a new PHP block in the Page Builder.

Now you can use my code to add Daily Quotes to homepage.
