Why Use PHP Frameworks?

PHP frameworks offer solid extensible architecture, with features that make source code programming easier by providing standard templates, components and plug-ins. Most of these PHP frameworks are supported by corporate or open source communities who offers solid Web development support. CakePHP, Code Igniter and Zend are some of the most popular PHP frameworks, with both advantages and disadvantages depending on your PHP requirements.

Advanced PHP programmers need more than basic source code for Web development projects. PHP frameworks offer convenient short cuts to improve efficiency, functionality, processing power and speed. Choose amongst different PHP frameworks tailored to satisfy specific coding needs.

CakePHP specializes in providing a strict, standardized extensible architecture for rapid application development using common design patterns for Model-View-Controller (MVC) and Object-Relational Mapping (ORM). CakePHP is best for novices to MVC who want a solid foundation for PHP coding.

There is a steep learning curve for CakePHP coding conventions, but many claim it is well worth it. CakePHP also has slower processing power measured in requests per second, compared to Code Igniter and Zend.

CakePHP supports MVC, multiple databases, ORM, database objects, caching, validation, Ajax and user authentication. CakePHP uses access control security. A strong open source community provides feedback, as well as, many useful components and plug-ins.

Code Igniter (CI) offers better immediate usage and common tools that are well-documented. Key advantages include compatibility, easy configuration and flexibility in coding rules.

CI supports MVC, multiple databases, database objects, templates, caching, validation and other modules. Code Igniter uses more traditional coding conventions. In tests measuring requests per second, the Code Igniter was considerably faster than either CakePHP or Zend for a series of measurements.

One disadvantage for CI is the need to write PHP source code for the creation of a "session class" for security purposes.

The Zend Framework (ZF) permits the growth of PHP programming with features such as pre-packaged applications, assistance in reducing defects and solutions tailored for different platforms (i.e. IBM, Linux and Windows). Zend also helps with cloud computing.

Web developers don't need to reinvent the wheel; be wise and reuse common PHP source code tools. Zend offers added flexibility in PHP source code writing. Zend supports MVC, multiple databases, database objects, caching, validation and other modules. It is feature rich and has better support due to corporate backing. Zend security is access control based. Zend was in the middle between CakePHP and Code Igniter in processing speed tests for requests per second.

Introduction to PHP Classes and Objects - Part 10

Classes and Objects:

The programming paradigm we have learned so far is called Procedural Paradigm. In Procedural programming paradigm, programmer writes a program as collections of independently behaving procedures and makes use of procedure call to access those procedures. As we already discussed in Part8, how procedural programming is a better choice than a simple unstructured programming. It has been a long time, programmers have started thinking about new paradigm called Object oriented paradigm (OOP) which provides a better way to develop big and complex system than procedural programming. We don't want to confuse readers by putting too complex terms and advantages of OOP at this stage, we will discuss when required.

In OOP, a class is a language construct that is used as a template or blue print to create instances of class called objects. This tutorial explains step by step to make the things clear.

Creating Class

Example#1

The example below creates a class called Person. It has two instance variables; name and address and few methods. The instance variables are not accessible outside the class when they are defined as private; we need methods to access them. But public variable can be accessed outside the class. All instance variables should be kept private and there should be some methods to access those variables. Here, we have SET and GET methods which are be public. All methods should be public; otherwise they cannot be accessed outside the class.

After the end of class, we have created a instance "p" of class "Person". "p" is called object of class "Person". Note that, "p" object binds instance variables and methods together, that property of OOP is known as encapsulation.

The output of the above code will be:

Gary Tom Unit 10 Nelson Bay, NSW 2030 Australia

Constructor and Destructor

When we create an object constructor method is called, hence it is useful to initialize the instance variables before they are ready to use. Similarly, destructor method is called when we destroy the objects.

Example#2

The code we have in this example produces the same output as in example#1, but has been implemented in a different way. Here we initialize the instance variables using constructors.

This code will also produces the same output as in example#1, that is:
Gary Tom Unit 10 Nelson Bay, NSW 2030 Australia

Inheritance

As the name suggests, inheritance is a principle by which child class can inherit the methods form its parent class and the methods performs their original functionality.

Example#3

In this example, we extend a class called Student from the class Person. The subclass Student inherits printMe methods and all instance variables from the parent class Person. The printMe method of Person class has been rewritten with the same name in Student class. If a method with same name exists in parent and child class, the child class object has two version of the same module. In this situation the child class method overrides the parent class method, it known as method overriding. When we call printMe method of Student object, it calls printMe of Student class not the printMe of Person class. Remember that all data members of Person class are available in Student class.

AJAX Tutorial - Loads of Information Available Online

It's often a difficult scenario on the part of an I.T aspirant to get into a thorough analysis of the particular subject matter but since the advent of internet as a valuable source of information, there have been the emergence of tutorials that are available online related to Ajax. The first and foremost tutorial defines AJAX that stands for Asynchronous JavaScript and XML. It is the use of the nonstandard XMLHttpRequest object to communicate with server-side scripts. It can send as well as receive information in a variety of formats, including XML, HTML, and even text files. The tutorial provides with Ajax's most appealing characteristic, of having an "asynchronous" nature, which means it can do all of this without having to refresh the page.

The Ajax tutorial gives an introduction to ECMAScript for XML (E4X), a simple extension to JavaScript that makes XML scripting very simple. The tutorial has related information on how to make asynchronous requests with JavaScript and Ajax, informative material on Ajax - Try/Catch Blocks of Code, sending requests with XMLHttpRequest to allow user to make requests and receive responses, adding AJAX to a website, Form validation with AJAX/PHP/MySQL, Callbacks and Ajax where user sets the onreadystatechange property of the XMLHttpRequest object to the name of the function to run. Then, when the server has processed the request, it will automatically call that function, to build Ajax-enabled applications using Dojo and JSON, the two very different but complementary technologies that can significantly enhance the interface and usability of web applications and more reference tutorials.

There are mini-tutorials on the black art of iframes and browser history, known to AJAX experts but rarely presented clearly, mini-tutorial on saving state across page loads on the client side, without using cookies so as to save large amounts of data beyond cookies size limits, valuable and effective resource on Easy Ajax with jQuery, Top Ajax Poller Scripts, fast introduction to the basics of Ajax for people that already know how to write the server-side part of the process using servlets and JSP, AJAX username availability checking that allows a user who is registering for your site to see if the username they want to use is taken already or not, without having to submit a form and reload the page, RadAjaxPanel that exposes a rich set of client-side events which allow for easy and flexible use in a wide range of application scenarios and tutorial that explains on how to work with the XML Response or "The X-Files" and more in line in order to enhance and learn new aspects in AJAX. Online education therefore is the most reliable and active source for gaining knowledge for I.T. aspirants through, ASP, Java and AJAX tutorial and the internet is a vast knowledge based environment making things a little more easy with downloadable and accessible information relevant to AJAX.

MySQL for Beginners - How to Create a MySQL Database

Whether you are an experienced web programmer or a complete novice attempting to provide data interactivity with your web site, MyQSL is an easy to use and free database solution that can allow you to store and configure data to be displayed on your web site.

The best way to create and manage a MySQL database is to download an open source (free) program called PhpMyAdmin. PHPMyAdmin allows you to manage all aspects of both your database structure and data from one easy to use interface. This tool is intended to handle the administration of MySQL over the Web.

This tool provides an interface that allows you to create and drop databases, create, drop, or alter tables, delete, edit, or add fields, execute any SQL statement, manage keys on fields, manage privileges, and import and export data into various formats. That sounds like a complicated set of activities, but the easy to use graphical tools make things quite simple and easy to understand. If you make a mistake, the software even provides instructions on where you made your error.

Most Linux based web hosting companies provide PhpMyAdmin as a standard feature with their packages. It is also available in a “Windows” IIS version. If your hosting provider does not already have this product installed they will often install it for you, or even allow you to install it yourself. Setup is quick and easy if you follow the step-by-step installation documentation.

Step One: Creating your new database

When you log in to your PhpMyAdmin welcome page, the first step is to enter a name for your new database in a text box provided. You can name your database anything that you wish, however if you are creating the database to use with a script or software package that you purchased somewhere, the script provider will often suggest a “preferred” database name.
You should always create your database using the following format:

username_ databasename

Example: myusername_mydatabase

Your complete database name should always begin with your username followed by an underscore, then followed by the database name. This allows the server to know which user is in control of the new database, and it will also provide permission to access the database to only specific users. This also allows different users on the same server to use the same name for their own database, as you did, without interfering with your data – that is helpful if more than one user on your server bought similar software for their own site. They can then also use the software providers “preferred” database name.

Step Two: Creating a table for your new database

After you have created a database, the next step is to create a table, or even multiple tables, for you to store data. A table is the part of your new database that actually stores data.

You create a table by selecting the database that you created from the drop box list of databases. Once a database is selected a new form appears and asks for you to create a new table.

You must decide what you want to name your table and enter that name into the name box. Try to choose a name that reflects the type of data that will be stored in the table, such as orders, users, or inventory.

You then must decide how many “fields” or columns of data that you want to store for each record. If you need for the table to store five (5) different items, such as username, users email address, users telephone number, users account number, and the users age, than you would need five (5) fields. Simply enter the number 5 in the appropriate box. Once you hit create, the system will create a table and will add those fields into the table for you. Don’t worry about the number of fields you might need right now, as you can always add or delete fields later.

Step Three: Defining Fields

Once you have created your table you will be prompted to tell the database what features that you want each field to have. This looks complicated, but it’s not if you select your data type from the information below. You basically have to decide between three common data types and select the best choice for storing your data. If you make a mistake you can go back and edit the field.
