Training on PHP

Description of PHP:-
Rasmus Lerdorf wrote the first PHP - first called Personal Home Page - scripts as a series of Perl scripts that he used to track visitors to his webpage and to see who was viewing his resume.

He eventually rewrote PHP as a scripting engine and added support for forms. Over the years the Personal Home Page acronym was dropped and it evolved into the PHP Hypertext.

PHP is freely available for use. The community of open source PHP developers provides technical support and is constantly improving updating the core PHP functionalities. PHP is available at free of cost under PHP General Public License and most of its associative required software's like MySQL, Text Editors and Apache Server are also freely available, so it proves very cost effective for the developers. 
PHP provides high compatibility with leading operating systems and web servers such as thereby enabling it to be easily deployed across several different platforms. PHP scripts can run across operating systems such as Linux, Windows, Solaris, OpenBSD, Mac OSX etc and also provide support for all major web servers such as Apache, IIS, iPlanet etc.
Several web tasks can now be easily perform using PHP. For example now we can develop from small websites to giant business and organizational websites, informative forums, chatting platforms, CRM solutions, e-commerce shopping carts, community websites, e-business, shopping carts and gigantic database driven sites.
User Friendly 
Designed in a user friendly manner, PHP gives more flexibility than C, C++ and ASP and overall helps in increasing traffic to the site
PHP is designed to work well with the web, and so things like accessing the GET and POST and working with HTML and URLs are built-ins in the PHP language. This makes it really concise and straightforward to make a website.
Being an open source language, a large number of libraries and extensions, to extend its core functionalities, are available for download. The source code of PHP can be modified to include custom created extensions and components thereby increasing its extensibility.
Easy Deployment 
There are many hosting companies that will, for a few dollars a month, give you a server running PHP so you can make a website really easily.
Automatically Refreshes 
Nowadays developing dynamic websites are in the huge demand due to its specific characteristics like it automatically refreshes and does not need to make much changes manually.
Community Support 
A huge advantage that PHP offers is its community. If you are looking for a particular script, chances are another user has already created something similar. Check within the PHP community for availability. Likewise, if you have created a function that others might enjoy, be sure to post the code for others.
PHP offers security as well that helps prevent malicious attacks. These security levels can be adjusted in the .ini file.
