Joomla @ Barcamp4(Feb 08 Pune)

  1. 1. What is php ?
  2. 2. What is php ? PHP is now officially known as “ PHP: HyperText Preprocessor ”. -It is a server-side scripting language usually written in an HTML context. -Unlike an ordinary HTML page, a PHP script is not sent directly to a client by the server; instead, it is parsed by the PHP binary or module, which is server-side installed. -HTML elements in the script are left alone, but PHP code is interpreted and executed. PHP code in a script can query databases, create images, read and write files, talk to remote servers - the possibilities are endless. -The output from PHP code is combined with the HTML in the script and the result sent to the user's web-browser, therefore it can never tell the user whether the web-server uses PHP or not, because all the browser sees is HTML.
  3. 3. What is php ? -PHP’s support for Apache and MySQL further increases its popularity. Apache is now the most-used web-server in the world, and PHP can be compiled as an Apache module. -MySQL is a powerful free SQL database, and PHP provides a comprehensive set of functions for working with it. The combination of Apache, MySQL and PHP is all but unbeatable
  4. 4. Boom for php There are some indisputable great reasons to work with PHP. As an open source product, PHP is well supported by a talented production team and a committed user community. Furthermore, PHP can be run on all the major operating systems with most servers. The speed of development is also important. Because PHP allows you to separate HTML code from scripted elements, you will notice a significant decrease in development time on many projects. In many instances, you will be able to separate the coding stage of a project from the design and build stages. Not only can this make life easier for you as a programmer, but it also can remove obstacles that stand in the way of effective and flexible design.
  5. 5. Why PHP 5 Rocks! PHP 5, which was released earlier this week, is the first major release of PHP in years to focus on new features. While one of the key goals behind PHP 3 was increasing PHP/FI 2.0's performance and efficiency, at the same time it introduced a whole new set of functionality. That was back in 1998. PHP 4 provided another speed burst, as it introduced the Zend Engine. However, the majority of PHP 4's changes were behind the scenes. Those features allowed more people than ever to use PHP, but it didn't provide them with more tools to build their sites. Finally, after six years, the community has revisited the legacy baggage that made tackling some problems unnecessarily difficult. In particular, PHP 4's version of object-oriented programming (OOP) lacks many features, the MySQL extension doesn't support the new MySQL 4.1 client protocol, and XML support is a hodgepodge.
  6. 6. <ul><li>Fortunately, PHP 5 improves on PHP 4 in three major areas: </li></ul><ul><ul><li>Object-oriented programming </li></ul></ul><ul><ul><li>MySQL </li></ul></ul><ul><ul><li>XML </li></ul></ul><ul><li>These items have all been completely rewritten, turning them from limitations into star attractions. While these changes alone warrant a new version of PHP, PHP 5 also provides a plethora of other new features. </li></ul><ul><li>In this article, I highlight seven of my favorite PHP 5 features. These features allow your PHP 5 code to frequently be shorter, more elegant, and more flexible than ever before. </li></ul>Why PHP 5 Rocks!
  7. 7. <ul><li>Upcoming changes in PHP 6.0 </li></ul><ul><li>PHP 6.0 looks to be an exciting release. </li></ul><ul><li> Nothing is absolutely fixed yet, but it looks like it will see the demise of three of my pet peeves: </li></ul><ul><li>register_globals, magic_quotes_gpc and safe_mode . </li></ul><ul><li>The first was just a big security hole, </li></ul><ul><li>The second messed with the data and made changing environments potentially nightmarish, </li></ul><ul><li>And the third was a misnomer that nobody really understood, and provided a false sense of security. </li></ul><ul><li>There's also quite a lot of work scheduled to do with Unicode. </li></ul>Future of PHP
  8. 8. What is Frame Work ?
  9. 9. <ul><li>A web application framework is a software framework that is designed to support the development of dynamic websites,Web applications and Web services. </li></ul><ul><li>The framework aims to alleviate the overhead associated with common activities used in Web development. </li></ul><ul><li> For example, many frameworks provide libraries for database access,templating frameworks and session management, and often promote code reuse . </li></ul>What is Frame work ?
  10. 10. What is Joomla ?
  11. 11. <ul><li>Joomla is a free, award-winning content management system written in PHP which allows users to easily publish their content on the world wide web and intranets.  </li></ul><ul><li>Joomla is created as an open-source project where individuals and teams contribute their skills to its development as well as its supporting systems. </li></ul><ul><li>While Joomla is packed with features, its greatest quality is that it is extremely extensible.  Because of its extensible structure, there aren't many things you cannot do with Joomla.  </li></ul>What is joomla ?
