Question 1: [20 marks] 1) Consider an array of integers that contain the numbers 1, 2, 30, 11, 17 and 3. Write a PHP code that loops through this array, counting and printing out the number of odd integers within the given array.

[5 marks]

2) What is a function? And what is it useful for in programming?

[5 marks]

3) Using PHP, implement a function that calculates recursively the factorial of a given number below 100. The function should return 0, in case the passed value exceeds 100.

[10 marks] Question 2: [20 marks] 1) Explain the concepts: object, class and constructor, stating what they are useful for.

[5 marks] 2) Write a PHP code that creates a class called “Book”. Objects of the class “Book” share the same publisher (e.g. Springer). They all have titles, authors’ names and publishing years. Implement a method within the class “Book” that prints out the above properties of a certain book, that is, its title, author’s name and the publishing year [10 marks] Example for the desired output: “This book has the title: Computational Complexity It was published by Springer in 2012.

The author of the book is Robert Meyers.

3) A) Explain what “object inheritance” means and what it is useful for.

[5 marks]

B) Create a class that does nothing but inherits the properties of the class “Book”. Let the name of the class be “Field”. To show inheritance, create an object (e.g. aBook) of the class “Field”, passing the printing method in part 2) of Question 2 to that object.

Question 3 [20 Marks] 1) Explain what a database (in general) is, providing a definition of a relational database [5 marks]

2) Why does the design of the database matter? And how does normalization contribute to a good database design?

[5 marks]

3

3) List three types of table relationships in relational databases with brief description of each type?

[5 marks]

4) Using the eLibrary (available through the LMS), search for other forms than the three normal forms presented in class. Your answer should include names, brief descriptions of these forms and a brief comparison between these forms and the three rules discussed in the lecture.

[5 marks]

Question 4 [40 marks] Using PHP and MySQL database engine develop a photo sharing system (Instigram-like) that implements the following basic functionalities: 1) Membership registration (7 marks) 2) Photo uploading (7 marks) 3) Photo comments (7 marks) 4) Admin area (to administrate the entire content management system) (12 marks) 5) Log-in log-out module (7 marks)
