Cake PHP is a free, open-source, rapid development framework for PHP. It’s a foundational structure for programmers to create web applications. Our primary goal is to enable you to work in a structured and rapid manner–without loss of flexibility.

Cake PHP takes the monotony out of web development. We provide you with all the tools you need to get started coding what you really need to get done: the logic specific to your application. Instead of reinventing the wheel every time you sit down to a new project, check out a copy of CakePHP and get started with the real guts of your application.

CakePHP is a framework, not a set of libraries, even though it contains dozens of functions and methods that simplify web development much like libraries do. As such, Cake waits on you to extend its objects and add your own customized resources. With Cake, gone are the days of individually scripting each and every function. Instead, developers are using a bundled package of scripts, libraries, and conventions that are designed specifically for web development.

Cake php is very strong and Rapid Development framework.CakePHP (or, for short, Cake) is a framework, not a set of libraries, even though it contains
dozens of functions and methods that simplify web development much like libraries do.

Cake php follows MVC framework Model-View-Controller.In MVC pattern business logic and application logic is seprate from each other. Cake enforces an MVC structure for your web applications. Basically, it effectively separates typical operations into specific areas: models for all your database interaction, views for all your output and displays, and controllers for all your commands/scripts for input and program flow. The typical PHP application mixes each of these three functions in the same code, making it difficult to maintain and debug.

This is the typical flow for PHP scripting

1. The client sends a request to a PHP script by typing a URL or clicking a link of some
kind.

2. The script processes the data and then sends the database requests directly to the
database.

3. The script receives any database output and processes the data.

4. The script generates output and forwards it to the client’s browser.

There are various features Of OOPS which are as follows:

Class:-A class is a user defines data type. This is a template definition of the methods and variables for a particular kind of object. In further words, class is the blue print from which an individual objects is formed. An instance shows class’s attributes through some public or private method.They are the class methods.

Objects:-Basically an object are the variable of user defined data type “class”.OOP viewpoint, an object is nothing but an instance of a class that contains real values instead of variables. Communication or exchanging data between two objects.

Abstraction:This is a concept by which we can only access the necessary attributes of that class without knowing more about the other attributes or methods. In object-oriented software, complication is managed by using abstraction. Abstraction is a process that involves classifies the critical actions of an object and eliminates inappropriate and difficult details.

Encapsulation:-Encapsulation is a method for protecting data from unwanted access or alteration by packaging it in an object where it is only accessible through the object’s interface.In more general term Encapsulation is the wrapping up of a data into single unit called Class.Encapsulation is frequently referred to as information hiding.

Inheritance:-Creating new class from parent class. Inheritance is the ability to define a new class or object that inherits the behavior and its functionality of an existing class. The new class or object is called a child or subclass or derived class while the original class is called parent or base class.

Polymorphism:-It means one name many forms. Mainly there are two types of polymorphism.

1. Compile time polymorphism - It is achieved by overloading functions and operators
2. Run time polymorphism - It is accomplish by overriding virtual functions.

LAMP  Technologies stands for Linux, Apache, MY-SQL, Peal/PHP/Python is a solution stack of software, generally free and open source software, used to run lively Web sites on servers.The original LAMP Architecture is as follows:

Linux is an operating system
Apache, is Web server
MySQL,is for database management system.
Perl, Python, and PHP, are the programming language.

The arrangement of these technologies is used mostly to define a web server infrastructure, describe a programming pattern of developing software, and create a software supply package for any application.

FUNCTIONALITY OF EVERY ELEMENTS OF LAMP

The most generally used Operating System for this purpose is Linux – it is Open Source too, and it is foundation on Unix which was an operating systems designed from the land up for a multi-user environment and for given that all the facilities a computer geek could probably want to do his work well, with security and with no restrictions at the Operating System level. The job of Apache’s is to hold requests, interpret it, and provide reply. In order for it to access the fundamental services on the server computer, it creates operating system calls on that computer.

In order for Apache to be able to run your (server) application, it desires to be told how that’s to be done - it needs to be programmed. Open Source languages like Perl, PHP and Python are used to do programming for applications. The MySQL database has become the “de facto” standard for many Linux - Apache - Perl / PHP / Python web applications construction up the contraction LAMP.

HTML generates static pages. They are used only to give you look and feel as how your website looks. Static pages are like body without life. So in order to give the life into static pages one can use PHP. PHP scripts are place at server which contains both static html page and PHP code. PHP also linked with the data base that stores the information about the audience to whom you want to reply back. Through this we can make the static pages as dynamic pages.

Advantages

1. Rapid and simple to put collectively even by someone who doesn’t have much knowledge.
2. Idyllic for indicating how a site will seem.
3. Cache friendly, one photocopy can be exposed to several people.

Disdvantages
1. Hard to sustain when a site gets big.
2. Not easy to carry on consistent and up to date.
3. Offers minute sightseer personalization (all would have to be client side).

PHP has many merits over other scripting languages. Some of them are as follows:

1) Speed - PHP is considered to be the best among the scripting languages. You can really feel the speed when you apply scripts live on the web. Usually when you try to link a database and obtain certain data, it takes time to connect the database, implement the statement and obtain the data across. Because of its high performance in terms of speed, PHP is being applied for some of the essential Web server administration such as mail functionality.

2) Open Source - PHP is an open source. This means users are known a free of charge license to remodel or recode PHP, according to their requirements. You may be surprised to know how this is possible without source code but source code is shipped with PHP - it is open source.

3) Multi Platform - PHP chains a variety of Plat forms, which means PHP can be installed on nearly all operating systems such as Windows-x and Linux, just opt the suitable version to download and go behind the instructions specified in the Manual accordingly.

4) Easy Syntax - PHP syntax is fairly effortless to code. It is comparable to that of the ‘ C ‘ language. If you are fresh to the programming background though, getting used to the syntax might be a bit hard.

PHP (recursive acronym for “PHP: Hypertext Preprocessor”) is a widely-used Open Source general-purpose scripting language that is especially suited for Web development and can be embedded into HTML.

What distinguishes PHP from something like client-side JavaScript is that the code is executed on the server. You can even configure your web server to process all your HTML files with PHP, and then there’s really no way that users can tell what you have up your sleeve.

The best things in using PHP is that it is extremely simple for a newcomer, but offers many advanced features for a professional programmer. So, don’t be afraid of using PHP. You can jump in, in a short time, and start writing simple scripts in a few hours!

The CGI(Common Gateway Interface) is a standard for interfacing external applications with information servers, such as HTTP or Web servers. A plain HTML document that the Web daemon retrieves is static, which means it exists in a constant state. A CGI program, on the other hand, is executed in real-time, so that it can output dynamic information.

Since a CGI program is executable, it is basically the equivalent of letting the world run a program on your system, which isn’t the safest thing to do. Therefore, there are some security precautions that need to be implemented when it comes to using CGI programs. Probably the one that will affect the typical Web user the most is the fact that CGI programs need to reside in a special directory, so that the Web server knows to execute the program rather than just display it to the browser. This directory is usually under direct control of the webmaster, prohibiting the average user from creating CGI programs. There are other ways to allow access to CGI scripts, but it is up to your webmaster to set these up for you. At this point, you may want to contact them about the feasibility of allowing CGI access.

A CGI program can be written in any language that allows it to be executed on the system, such as:

• C/C++
• Fortran
• PERL
• TCL
• Visual Basic
• Applescript
• Any Unix Shell

It just depends what you have available on your system. If you use a programming language like C or Fortran, you know that you must compile the program before it will run.  however,you can use one of the scripting languages instead, such as PERL, TCL, or a Unix shell, the script itself only needs to reside in the /cgi-bin directory, since there is no associated source code. Many people prefer to write CGI scripts instead of programs, since they are easier to debug, modify, and maintain than a typical compiled program. click on the link for more internet marketing articles. http://www.applelounge.com
