Create a Movies Class that determines the cost of a ticket to a cinema.

Are there any suggestions about the code I have created. I need to create a movies class that goes with Admission.php and Movies.html that I have created that determines the cost of a ticket based on the age. the full price of the ticket is 10.00. I need to assign the age to a private data member then use a public member function to determine the ticket price based on the following
under 5 = free
5-17 = half price
18-55 = full price
over 55 2.00 off full price
class Movies
	{

		private $age = 0; //declare private age
		private $ticketPrice = 10.00;//declare private ticket price 

                //create public function assign age       //it		
		public function Movies($age){
		$this->age = $age;
		}

		public function Movies($ticketPrice){
			
			if(age < 5){
			$this->ticketPrice = 0;
			}
			if(age > 5 && age < 18){
			$this->ticketPrice = $ticketPrice / 2;
			}
			if(age >= 18 && age <= 55){
			$this->ticketPrice = $ticketPrice;
			if(age > 55 ){
			$this->ticketPrice = $ticketPrice - 2.00;
			


	}

In your movies class, remove the second constructor Movies() constructor. You don't want a constructor, you want a function which retrieves the correct age given the provided values.

            public function Movies($ticketPrice){

should be

            public function getDiscountTicketPrice($ticketPrice){

Then in your Admissions.php, you should instantiate the class, pass the age into the constructor when you instantiate it, and then call the "getDiscountTicketPrice()" function, passing in the ticket price of "10.00". The function should return the "new" ticket price according to the age, assuming you wrote that function correctly.

You can then use that value wherever you like in your Admissions.php page (show it on the page somewhere, store it in a database, process an order etc.).

A few other minor things in your other pages:

1) Don't require Movies.html in your Admissions.php page. It is not required. The Movies.html page posts data to the Admissions.php page, the two are not dependencies of each other.

2) Change the "method" property of your form from "GET" to "POST" in your Movies.html. Your form should be posting the data to the Admissions.php page.

3) In your Admission.php page, you should be doing some error checking - e.g. what happens if the user posts invalid data, or no data at all? It should maybe redirect back to the Movies.html page or show an error message.

Sorry that should read "you want a function which retrieves the correct DISCOUNTED TICKET PRICE given the provided values"

I have made the changes that you suggested but I am still not getting it to work. I think I have something wrong in the admission.php
<----Admission.php--->
<?php
require_once("Movies.php");

?>

<?php



$ticketPrice = new Movies($age);
$ticketPrice->getTicketPrice();
$ticketPrice = 10.00;
$ticketPrice->getTicketPrice($ticketPrice);



echo"<p>The ticket price is $ticketPrice </p>\n";
