Anytime the price data is needed, it shall be retrieved programmatically from this array. It shall not be "hardcoded" anywhere else in the PHP document. To clarify, if the array contained different prices than the ones shown above, whatever prices are in the array would be used in all calculations and displays.

	The pizza menu shall appear in table form as shown above. The price data appearing in the table shall be obtained programmatically from the $pizzaPrices array.
	The order form shall allow selection of the kind of pizza (plain, vegetarian, pepperoni, or hawaiian).
	The order form shall allow selection of the size of pizza (small, medium, or large).
	When the user submits the form, the script shall run (again). The response shall display a receipt.
	The receipt shall include the kind of pizza.
	The receipt shall include the size of the pizza.
	The receipt shall include the price of the pizza. This price shall be retrieved programmatically from the $pizzaPrices array.
	The receipt shall include the amount of sales tax at 9.75%
	The receipt shall include the total price of the order.
	The receipt shall be in the following format: Hawaiian Medium $12.50 $1.22 $13.72
	All monetary amounts in the receipt shall appear in the following format: $13.72 Hint: Use the number_format() function (ending zero 13.70). See the PHP Manual ( http://php.net/manual/en/function.number-format.php (Links to an external site.)Links to an external site.) for usage.
