Brief History of PHP

PHP (PHP: Hypertext Preprocessor) was created byRasmus Lerdorfin 1994. It was initially developedfor HTTP usage logging and server-side formgeneration in Unix.

PHP 2 (1995) transformed the language into a Server-side embedded scripting language. Added databasesupport, file uploads, variables, arrays, recursivefunctions, conditionals, iteration, regularexpressions, etc.

PHP 3 (1998) added support for ODBC data sources,multiple platform support, email protocols(SNMP,IMAP), and new parser written by Zeev

Suraski and Andi Gutmans .

Brief History of PHP

PHP 4 (2000) became an independentcomponent of the web server for addedefficiency. The parser was renamed the ZendEngine. Many security features were added.

PHP 5 (2004) adds Zend Engine II with objectoriented programming, robust XML support

using the libxml2 library, SOAP extension forinteroperability with Web Services, SQLite hasbeen bundled with PHP

3. Cost Benefits

PHP is free. Open source code means that the entire PHP

community will contribute towards bug fixes. There are

several add-on technologies (libraries) for PHP that are also

free.

Getting Started

How to escape from HTML and enter PHP modePHP parses a fileby looking for one of the special tags that tells it to startinterpreting the text as PHP code. The parser then executes all ofthe code it finds until it runs into a PHP closing tag.

Simple HTML Page with PHPThe following is a basic example tooutput text usingPHP.

PHP is a great way to implement templates on your

website.

How to implement a simple page counter

7/31/2019 PHP An Introduction

14/39

Examples

Step 1: Universal header and footer in a single file

Step 2:Create a file called header.php. This file will have allof the

header HTML code. You can use FrontPage/Dreamweaver tocreate the header, but remember to remove the closing and tags.

Step 3: Universal header and footer in a single file

This is the basic template that you will use on all of the

pages. Make sure you name the files with a .php extensionso that the server will process the PHP code. In this example,we assume the header and footer files are located in thesame directory.

7/31/2019 PHP An Introduction

ExamplesBenefits:

- Any changes to header or footer only require editing of a

single file. This reduces the amount of work necessary for

site maintenance and redesign.

- Helps separate the content and design for easier maintenance

What is CMS

The name CMS, Content System Management, is

a vague term, since actually any software

manages contents.

More precisely one gives this name to a softwarewhich manages the creation and the publication

of documents, possibly in a collaborative way.

On this site, we will speak rather about CMS as

Web applications, therefore software of

assistance to put documents in line on Internet.

7/31/2019 PHP An Introduction

18/39

Why a CMS?

Content managers undertake the part common to the pages of your

site and generates the pages starting from the text or of the data that

you provide him. He thus delivers you repetitive tasks.

He can be static and create the pages before they are put in lines, or

dynamic and create the page at the request of the visitor.

He does not bring anything about the contents itself, but makes it

possible to manage the structure of the site, to add and classify the

pages. The major CMS make it possible to manage a forum, a

directory, news, most of the time by the addition of extensions.

Sometimes it makes it possible to adapt the interface of the site, to

generate more stripped printable pages or to make contributors

taking part to the site.

Joomla Introduction

Introduction to the popular Joomla CMS (ContentManagement System) and its use. This strangename was chosen among many others! It is aSwahili word that expresses the community vision

of the tool.Joomla uses are quite varied: portal, magazine, e-commerce.

In April 2010, Microsoft has signed the Joomla!

Contributor Agreement and now contributes tothe code for it to work better on its WindowsIIS server.

Print format for each item.

Sending emails to announce a new article.

Insertion of a poll in each article (available on Drupal too).

Banners manager.

Custom look and feel selected by each user.

Search field associated with a statistical research tool for the site.

Syntax-hightlighting for code.

Possibly assigning a different template for each page.

Integrated Forum (Extension).

Integrated FAQ (Extension).

Drawbacks of Joomla

Documentation is the weak point of this CMS. We donot even see on the site a list of features of thesoftware, we must pick them up on other sites. Apart aPDF file somewhere on the site I found through

Google.The wiki and more precisely theAbsolute BeginnersGuide to Joomla provides some information.

Joomla has only two levels of hierarchy whileWordpress allows you to add sub-categories without

limitation. That's enough for a site of entrerprises or e-commerce but Joomla is not suitable for adocumentary website.

Drupal Introduction

Drupal is a content management systemautomated with which the user can simply writewithout worrying about categorization and otheraspects of site management. But considered in

this way, Drupal must be installed by anexperienced webmaster, because the originalsetup is limited to basics, there is not even amenu of categories, and it is with the addition of

modules that we will provide to a site all thefeatures of the Web 2.0: tag cloud, display ofrecent articles, RSS feeds, statistics of visits, etc..

7/31/2019 PHP An Introduction

26/39

Advantages of drupal

The CCK is now part of the core software and is no longer a module.The Content Construction Kit allows to create new types of pages.

Like Wordpress, you can upload images and make manipulations.

The interface is simpler, more intuitive.A designer has been specially hired to redesign the interface.

An update manager is added. Custom fields allow to extend the pages without creating new

types. This comes from Wordpress.

All databases may be used now as the software interacts with aninterface layer.

The Drupal Theme Garden is a repository of themes under the GPL,thus freely usable.

Drupal 7 is faster due to improved access to the database.

7/31/2019 PHP An Introduction

27/39

Disadvantage of drupal

Drupal is compatible with the data but not withthe code. A new version may require thewebmaster or module developer to change thecode he added to suit the new version.

But they may still use the contents of thedatabase.

However, the code compatibility is maintainedbetween minor versions.Drupal 7 becomes

incompatible with Drupal 6, but Drupal 6.1, 6.2,6.3 etc. remain consistent when the code ofDrupal 6.0.

Wordpress Introduction

Wordpress is both a host ofblogs, Wordpress.com with four million hostedblogs in 2008

There are other blogging software such as

dotclear, but Wordpress, through its manycontributors has a very broad range of pluginsand themes that make it nearly universal andprovides almost all the features that we could askfor. We can give it also a more general use,building even a platform for e-commerce.In addition it makes low use of resources and isoptimized for SEO.

Advantage of Wordpress

1. Cheap or FreeUsing WordPressfor your website means its cheap or free.WordPress itself is free, a theme is easily under $100 or evenfree and you save loads of money (compare the cost oftemplatevs custom design). Havent you heard? Stingy is in.

2. Its That EasyIf youve got any computer savvy, WordPress is easy to use. If youcan send an e-mail, use Microsoft Word or set up a Facebookaccount, then you can use WordPress. And normal use doesntrun the risk of mucking up the design. Its website creation fornon-techies.

3. Do It YourselfWith WordPress you enter the Do-It-Yourself world. No morewaiting for and paying a programmer to fix a tiny error, savingyou time and money.

Advantage of Wordpress

4. Many Users, Many PlacesWordPress is online and offers multiple users, which meansyoure not the only one who can fix something in a pinchand you can access it from anywhere. Which means ifyouve got Internet access in Tahiti, you could work from

there. That also means your important site is backed up ona secure server with multiple redundancies, not some highschool kids laptop.

5. Climb the Search Results

WordPress also makes it easier to optimize your searchengine results. That means your site is more likely to landon the first page of Google results, which means people aremore likely to find you.

7/31/2019 PHP An Introduction

31/39

Disadvantage of Wordpress

Many of the themes have a tendency to lookthe same or similar.

PHPs track record for security is pretty bad.

Database queries may be very heavy It isnt a full CMS product which is fine for a

lot of sites but if your site is moving a long

way away from something based around ablog then you might find it starts to creak abit!

7/31/2019 PHP An Introduction

32/39

What is framework

The idea behind a framework is to offer a design you can

use across multiple applications. All applications have a

number of basic things in common.

A framework is designed to provide a structure for those

common elements (database interaction, presentationlayer, application logic) so you spend less time writing up

database interface code or presentation-layer interfaces

and more time writing the application itself. The

architecture represented by breaking an application up inthis fashion is referred to as Model-View-Controller

(MVC). Model refers to your data, View to your

presentation layer, and Controller refers to the application

or business logic.

7/31/2019 PHP An Introduction

33/39

Why a framework

There's a reason why PHP is growing rapidly as aserver-side scripting language it's very easy topick up. Many functions are included withoutneeding any sort of namespace importing, and you

don't even have to write OO code if you don't wantto. Variables are weakly typed and the syntax isfairly familiar.

But PHP's ease of use is also its downfall. Because

there are less restrictions on the structure of thecode you write, it's much easier to write bad code.But there is a solution: use a framework.
