WEB is a computer programming system created by Donald Knuth as the first implementation of what he called "literate programming": the idea that one could create software as works of literature, by embedding source code inside descriptive text, rather than the reverse (as is common practice in most programming languages), in an order that is convenient for expostition to human readers, rather than in the order demanded by the compiler.

PHP has come a long way in the last few years.
Growing to be one of the most prominent languages
powering the Web was not an easy task. Those of
you interested in briefly seeing how PHP grew out
to what it is today, read on. Old PHP releases
can be found at the
» PHP Museum.

Why database abstraction layer ?
A database abstraction layer is a database-independent interface, it is
a layer of abstraction over the actual database access methods and
allows developers to deal with different databases without changing
their code on a per-database basis.
By placing a layer of abstraction between the database and the
developer, the database abstraction layer insulates the programmer
from database implementation details. If you initially write a script
to talk directly to Oracle for example and later need to have it work
with another database server, you will have to rewrite all the
database-specific parts but If you use a database-independent API, then
all you need is just to change some littel settings, Pear provide us DB
data object that give us good features to accomplish this technque.
Now to the Examples

Regular expressions is a way to describing a pattern in piece of text, PHP supports two styles of regular expressions syntax : POSIX and Perl, The Posix style of regular expression is compiled ito PHP by default , but you can use the Perl style by compiling in Perl-compatable regular expression (PCRE) libraray.
If you used the php matching functions you will note that all pattern matching you have done used String functions, and you have been limited to exact matches, So if you want to do more complex pattern matching you should use the regular expression, it is difficult at first but it is extremely usefull.

The character encoding is a code that pairs a sequence of characters from a given character set with some thing else to represent it in a form which you can store and transmit it in telecommunication networks, the given characters form before encoded is called character set.

JSON (Javascrept Object Notation) is a lightweight computer data interchange format. It is a text-based, human-readable format for representing objects and other data structures and is mainly used to transmit such structured data over a network connection (in a process called serialization). JSON finds its main application in Ajax web application programming, as a simple alternative to using XML for
asynchronously transmitting structured information between client and server. JSON stands for Javascrept Object Notation.

Ajax, or AJAX, is a web development technique used for creating interactive web applications. The intent is to make web pages feel more responsive by exchanging small amounts of data with the server behind the scenes, so that the entire web page does not have to be reloaded each time the user requests a change. This is intended to increase the web page's interactivity, speed, functionality, and usability.

Model-view-controller (MVC) is an architectural pattern used in software engineering. In complex computer applications that present a large amount of data to the user, a developer often wishes to separate data (model) and user interface (view) concerns, so that changes to the user interface will not affect data handling, and that the data can be reorganized without changing the user interface.

Hi guys,
Today I'm starting to post in my new blog which is a part of my small community, and I hope to grow it up.
I'm posting about Open Source, PHP, Web, and FreeBSD.
and this is some related links to it and the community:
