Some experience though I must note still limited had learned me that too many languages is producing only problems. And furthermore it is not needed to have strict coding because it is important to keep zour site to the brwoser compatibility and not in fact strict though many people consider strict code as compatible but many times if you try to check it out even if your code is strict you might have problems with code however the point also is that you want to allow your site to be viewable by as may users possible however the thing is that you must consider compatibility this is the thing I hold usually when coding

And best combination to combine is to use javascript then css html php and mysql.

javascript for modification of the page in real time without almost without communication with server. Under javascript I consider ajax also that is the reeason for the almost there

css for the basic look and feel of the page site or however you like to conside rit. And also it is better to use this then to modify with ccss then with the html tags since it is easier to modify and change page afterwards or to make more templates and so on.

html. as basic for the organization of all elements in the page and everything else for providing outputs from the php ad so on.,,.

php as server side scripting opposite to teh javascript sinve with this you can manipulate all bunch of the things like logins sessions registrations very different data and so on. Almost everything you think.

mysql ought to be used for communication between php and database server and to pull out and send data inot databases. The rgeat engine though there are some misuses like sql injections.

Maybe it's just a personal thing, i love to keep my pages coded in proper formats

Although i understand what your saying, compatibility is THE most important thing when designing. All viewers should see your website identically or as close as possible to each other. I have 4 browsers installed on my PC to make sure of that. Each programming language brings it's own features to the table, you have noted each one pretty well

PHP is simply what makes web dynamic , for example : forums , online rpg games , mails , etc ... is made by php
Without php we'll just see the same things all the time

PHP stand for HyperText Preprocessor. PHP is a scripting language used to create dynamic web pages for various web applications. However, PHP can also be used in command line scripting and or graphics applications. PHP is compatible with virtually any type of Operating System, Hardware Architecture, or web server.

PHP is one of the most commonly used server side scripting languages today. It initially meant Personal Home Page Tools (PHP Tools), but now stands for Hypertext PreProcessor.

Server Side scripting languages are languages that can be used to perform actions on your web pages based upon inputs or actions taking place on the client side.

There are also many client side languages like javascript available, but server side languages are more secure and offer more functionality when it comes to building dynamic websites.

A simple example is,

- say you go to a email provider's website and click the sign up button.
- You are taken to a page containing a form which is to be filled by you to register your email account.
- On filling the form you click the submit button.
- Upto this point of time plain HTML is sufficient enough to perform all the tasks.
- On clicking the submit button a server side scripting language such as PHP is required to gather the data and perform some action on it such as sending the form details to some email address, or submitting the form details to a database.

PHP is a free software which can be run on Apache and Windows servers. It is most famously known for its use in a bundle with PHP, MySQL and Apache. You can embed PHP code into web pages within the delimiters <?php and ?> . Object Oriented functionality is available in PHP. It was introduced in PHP3. Since then many OO features were added to make PHP a powerful language.

PHP is a programming language, with PHP you can make e.g. a website/forum/portal etc.

also PHP stands for = PHP Hypertext Preprocessor

PHP stands for (PHP: HyperText Preprocessor). It is a server sided language which therefore must be used with a server. PHP was originally created by Rasmus Lerdorf in 1994, the main implementation of PHP is now produced by The PHP Group and serves as the de facto standard for PHP, as there is no formal specification. Released under the PHP License, the Free Software Foundation considers it to be free software.

The actual first name of PHP in 1994 when it was created was officially called "Personal Home Page Tools (PHP Tools)". Then in the release of V3.0 the PHP company called it by what we call it today.

Some of the simple tags that people use everyday are

CODE

echo "Hello world";

CODE

$POST, $GET, $REQUEST

(these are otherwise known as super globals)

The POST GET and REQUEST were not actually introduced until 4.1.0 release on December 1, 2001.

the better question is WHY PHP and not other web developing language.
the answer is:

* PHP will run on (almost) any platform. Using the same code base, PHP can be compiled and built on about 25 platforms, including most UNIXs, Windows(95/98/NT/2000) and Macs. As this uses the same code base, all scripts will run identically, whatever the platform.
* PHP is similar to C. So anyone who has experience with a C-style language will soon understand PHP. In C-style languages we can also include Javascript and Java. In fact, much of PHP's functionality is provided by wrappers around the underlying system calls (such as fread() and strlen()) so C programmers will immediately feel at home.
* PHP is extendible. PHP consists of the core parsing engine (written by Zend), a set of core code modules and then a set of code extensions. This allows programmers two ways of extending PHP to do some special processing, either by writing an extension module and compiling it into the executable, or by creating an executable that can be loaded using PHP's dynamic loading mechanism.
* Lots of HTTP server interfaces. PHP currently will load into Apache, IIS, AOLServer, Roxen and THTTPD. Alternatively, it can be run as a CGI module.
* Lots of database interfaces. PHP currently will work with MySQL, MS SQL, Oracle, Informix, PostgreSQL and many others. These are binary level interfaces, and ODBC is also provided for those situations where the database is not supported.
* And lots of other modules... when a PHP user wants to interface to particular library, then it is easy to write an interface for it, and many have done so, and contributed to the main PHP source repository. So you can find modules for graphics routines, PDF files, Flash movies, Cybercash, calendars, XML, IMAP, POP and a host of others. If the library you need is not supported, you can either write one yourself, or employ your favourite programmer to do it.
* PEAR. The PHP Extension and Add-on Repository. Similar to the CPAN network for Perl, although still in its infancy, the idea of PEAR is to provide a set of PHP scripts that would be installed by default with the PHP installation
* Fast. PHP is normally used an Apache module and this makes it very fast. It is entirely written in C and is quite small, so loads and executes quickly with small memory footprint.
* PHP is Open Source. Almost a religious matter to some people! In purely practical terms, it means that you are not dependent on a manufacturer to fix things that don't work, nor are you forced to pay for upgrades every year to get a working version. Those of us who have waited for Allaire to get something fixed will appreciate this.

PHP = PHP Hypertext Preprocessor

I believe it means "Prepreocessed Hypertext Programming".

But, yes, PHP is a server-side scripting language that allows you to view pages' output without displaying the source code. This is especially useful if you have a trade-secret script (for example, this forum's credit system) that you don't want anyone to see.

Knew it was server sided, but never knew of the many acronyms
