How would you create PHP pages/classes/methods to allow users to add a new actor record. The form should have appropriate controls to enter an actors first name (NameFirst), last name (NameLast), age, gender and agent (ActorAgent). Include appropriate client-side validations for each control. Note: Gender is stored as M or F in the database.

Add one or more records to the Actor table to test your code. You can enter any acceptable values for the NameFirst, NameLast, Age and Gender columns. But for ActorAgent, enter your full name (e.g., Jane Smith; without any initials or periods) for every actor record that you add.
