  1. Been studying your book for a while and noticed it is not too much different from the 4th edition. The book's using mysqli_ for database connection, and the php is still version 5.some. Meanwhile, php 7 has come to life and the pdo is ubiquitous nowadays. As well as MVC and more or less object oriented approach in general. Some books i know of (i'm not sure if i can mention them here) went through this and even their hands-on practice evolved from developing a simple CMS to an almost framework-like application. So, my question is: will you update your PHP & MySQL series?
  2. I'm having trouble understanding/linking the code example to the diagram and definition for the Factory Pattern. abstract class Shape { ... } class Rectangle extends Shape { ... } class Triangle extends Shape { ... } abstract class ShapeFactory { static function Create($type, array $sizes) { switch ($type) { case 'rectangle': return new Rectangle($sizes[0], $sizes[1]); break; case 'triangle': return new Triangle($sizes[0], $sizes[1], $sizes[2]); break; } } } $obj = Shap
  3. I am a OOP-newbie - and I like this book a lot :-) None of the the two classes in the chapter, User and Page, have a $pdo in the constructer. This means that all db-handling(select, insert) is in the controller-pages and not in the classes. There could be a getUserName-method in the User-class, but no. I found another userclass on the internet where the $pdo is in the constructor, and then I can make a getUserName-method. BUT - if I then want to make some of the db-handling in the controller-page and not inside the class, the $pdo is required in the constructor, if I want to fetch data
  4. In Chapter 5 on pate 157 it says in a darker portlet: I need some more details on this. What concerns me is that I created a file in which I included Rectangle.php then I declared a new class such as: class Square extends Rectangle { } just an empty class and then called: $r = new Square(); for testing purposes I added the following line to Rectangle's constructor class: print "construction called"; and it does seem to be executed when new Square class is instantiated with no parameters passed! Is the documentation in the book wrong or am I missing something? Because the abo
  5. In this example why does the procedural way fail with this error: Error: Warning: mysql_fetch_assoc() expects parameter 1 to be resource, object given in /Users/joel/Sites/people_test/public_html/index.php on line 14 PHP: $dbc = @mysqli_connect (DB_HOST, DB_USER, DB_PASSWORD, DB_NAME) OR die ('Could not connect to MySQL: ' . mysqli_connect_error() ); $q = "SELECT first_name, last_name FROM person LIMIT 0,30"; $r = mysqli_query($dbc, $q); Procedural: while($data = mysql_fetch_assoc($r)) { $rows[] = $data; } //prints out null echo json_encode($rows); OOP: while($data = $r-&
  6. version 0.5 Page 129 As I read this book, I keep scratching my head, wondering what's so good about OOP (Object Oriented Programming). The clips example is a case in point. Why write 5 lines of code when you can write just 2, like this? $stockQuote = 'AAPL: $533.25'; echo $stockQuote; I can modularize my procedural code by using includes. So how can all the fuss and bother of OOP be worthwhile? I've read plenty of rationales defending OOP, written by people who studied it in college, but it seems more like a religion to me. Sorry, I don't mean to offend anyone. I've re
  7. Hello Larry, Thank you for all your help, I learned many things reading your books and now I am back to the desk for learning after many hours of producing. You were right that a programmer may have a very nice life doing procedural programming and I have to say that I finished a quite big project and I didn't mind 'repeating myself' as in fact was not that bad, put things in functions and the repeating part was rather easy: copy/paste and changing a few things. I like the fact that I can keep things separate, HTML, SQL, PHP, CSS. Anyway... I've got so used with your way and the patterns I
  8. Hi, still teaching myself, Larry's books are great. As I am not in the computer field, when I go to places like PHP.net for info I usually can't figure out what they are really trying to say to me. I hope that my question below is proper for this forum, if not please excuse my question and I will respectfully withdraw it. I bought the PHP 5 Advanced book really to learn OOP, something very new to me. I am able to work through Larry's examples an do eventually get things to work when I modify the examples, to be sure I understand how the coding works. I took Script 3.1 db_sessions.in
