The low hanging fruit of OO PHP

[*] First configuration file.

config.php

<?php
ini_set('include_path',ini_get('include_path') . '../SPLIB:' . '../pear:');
?>

location: ../config
[*] Connection to the MySQL database.

connection.php

<?php
require_once('../config/config.php'); // Configuration file
// Include MySQL class
require_once('Database/MySQL.php'); // In SPLIB

$host='db.name.com'; // Hostname of MySQL server
$dbUser='Your user name'; // Username for MySQL
$dbPass='your password'; // Password for user
$dbName='Name of SQL DB'; // Database name

// Instantiate MySQL connection
$db=& new MySQL($host,$dbUser,$dbPass,$dbName);
?>

location: ../connection Only for testing. Hide it in your applications.
[*] SQL text files imported to MySQL via phpMyAdmin.

Why reinvent the wheel?

While I agree there are some great php libraries already available I think it's imporant to build your own classes (framework) for some of the core day to day tasks. I think an application developer (even online applications) should know what every line of their core application does, with external libraries restricted to bolt-on functionality.

Sorry to distract from the initial purpose of this thread, some great resources posted so far kgun

No problem. Discussion is very important. My remarks. Imagine 5 levels from basic to advanced.

I agree with you when you start on OOP. You must know what is going on.
When finished with that level, you start using third party libraries, like PEAR and SPLIB.
At the next level you are able to read a class API like you read a manual. You learn a form of language where the different classes become elements ("words") in your library. You look at the class / API and know how to use it and extend it. You extend it by going from general to more specific tasks. That is about (multiple) inheritance.
At this level, you can use different OOP languages. See OopSchool in my signature for resources.
At this level you can write the most advanced hosted applications in C++ and distributed objects in e.g. BETA.

Most webmasters should be able to manage the first three levels. The learning curve for OOP may seem steep, but once you grasp it, you will love it.

Favourite link?
Borland Developer Network.

When I studied Borland C++ Builder and C++ in the mid 90's, every serious developer knew that the Borland compiler was lightyears ahead of Microsoft's C++ compiler. You could even use the MS C++ class library in the Borland Compiler. That library naturally had its strenghts on MS operating system(s) classes.

I think that Borland's C++ builder is still one of the best developement tools, but Borland is not that clever on marketing as for example Microsoft and Google. You do not need that for developing Web Applications.

OOP in PHP becomes easy when you know C++. So if you are a young web developer, my advice is, take a course in C++ and learn to handle Borland's C++ Builder. When you handle it and understand the code, you can read OOP PHP code like others read a book.

What has caused me most frustration in compiling code and putting code on the web / test server, is configuration, includes, libs, resources etc. etc. So start by studying the / your environments and learn to handle them, before you start on using third party libraries.

I have tried to make that clear in my example above with the config.php file.

Registration form. If you sign up you are registered in my database. Do not call it spam if you get an email.
Login after registration.

[*] How secure is the solution? [*] Can you use it? Yes, if you have (part of) the PEAR class library installed on your web server and if you have the SPLIB library that follows with the book. I think you get that for download as soon as you have bought the books. I am not an affiliate of SitePoint and get no commision for reccomending the books. [*] Note, the solution uses the Session class. That means that you are logged in as long as there are no timeout or you log out.[/list:o:933da64f26]

Don't submit the form with your credentials unless you want to register in my client database and get future OOP information. That is your responsibility.

As long as you do not use SSL it is not easy to make the registration more secure than this form.
Features:

Random image text verification.
Confirmation email.
Double checking Authentication.

$imageText->addText($session->get('randomString'));

// Send the right mime type

// Display the image
ImageJpeg($imageText->getImage());
?>

You also need the image File: reg_image/reg_image.jpg

We are a week from Christmas. If you are a PHP developer, I can reccomend the following book:

Matt Zandstra (2004): "PHP 5 Objects, Patterns, and Practice." ISBN 1-59059-380-4.

If you are starting on PHP, learn Design Patterns from the very start and make it object oriented. That may save you time and money. You will know why when you read that book. There is a major step in OO direction from PHP 4.x to PHP 5.x.

Code that functions in PHP 4 may not longer function in PHP 5.x. Use the last version of PHP when you start your project. As of this writing that is PHP 5.2. If you are learning PHP, PHP 6.0 may be stable before you start on the real project.

Advice: Do not buy an old book that is about PHP 4.x or lower unless you are rewriting earlier code and you need to understand the difference.

I have not read the whole book, but I can tell you that the three frist chapters are worth the cost of the book.
