Me Santanu Boral, describe the PHP terms on the web where you can find additional information.

PHP which is officially known as ‘Hypertext Preprocessor’ was released in the year 1995. Initially written as a set of Common Gateway Interface (CGI) in ‘C’, PHP was originally designed to replace a set of Perl scripts to maintain his Personal Home Pages (also known as PHP). PHP was originally designed to create dynamic and more interactive web pages. It is the most widely-used, open-source and general-purpose scripting language. It is a server-side scripting language often written in a HTML context. PHP code in a script can query databases, create images, read and write files and talk to remote servers. The output from PHP code is combined with HTML in script and the result is sent to the user.

It is possible to use PHP in almost every operating system. PHP can be used in all major operating systems including Linux, Microsoft Windows, Mac OS X, and RISC OS. PHP uses procedural programming or object oriented programming and also a mixture of them. PHP is used mainly in server-side scripting, command line interface and writing desktop applications. PHP also supports ODBC, the Open Database Connection standard which allows you to connect to other databases supporting this world standard. Server-side scripting is the most traditional one for PHP development. In order to use PHP for server-side scripting you need a PHP parser, a web server and a web browser. The PHP codes entered with the parser on a web server will be translated into a PHP page that can be viewed on your web browser.

PHP is a popular language because it can be embedded directly into HTML coding. It has more benefits such as the following – it can be used on all major operating systems and can be supported by most of the web servers. The latest version of PHP development is a very stable and grown-up language used for web programming like Java and Microsoft C#. Both the PHP engine and the PHP code can be used on any platform, which makes PHP extremely flexible.

PHP has many features designed specifically for use in websites. PHP can be used to make your website secure by implementing mandatory sign in feature – asking the user or the administrator to enter a valid username and password. Adding such a feature is easy as PHP can display a HTML form and process the information that the user types in. This ‘sign in’ feature can be an excellent way of getting to know about your customer’s profile.

The popularity of PHP Development continues to grow rapidly because it has many advantages. PHP is fast because the time needed to process and load a webpage is relatively low. PHP is also versatile and it runs on a wide variety of operating systems. PHP hosting is a server-side scripting environment that is used to create dynamic web pages. It is an open source language which is widely used by programmers and web developers. Open source gives a lot of advantages over proprietary programming languages. Due to this reason, PHP has been the one of the most popular server-side scripting language so far. Almost all the hosting providers offer PHP hosting services these days. PHP is especially strong in relational databases, which are used for dynamic content and e-commerce applications.

PHP or HyperText Preprocessor is a server side scripting language used for creating dynamic websites. The script which is initially possessed by the server is then transferred to buyer via HTML files. The language is even used for command-line scripting and client-side GUI applications. More importantly, the back-end tool for PHP is My SQL, the interfacing property of My SQL, an online database, which matches with PHP. So webmasters, who want to make their web sites automated, can zero in on My SQL and PHP, to build dynamic websites.

Now coming to the point, the developers at Rightway Solution have acquired the required skills to deliver high-end PHP Solutions to its clients world-wide. The advantages of PHP are enumerated below:

Benefits of PHP

• PHP has been breaking new ground in the outsourcing world, with over 1,000,000 websites currently lapping up the benefits PHP language. Shaking off traditional static image of the websites, the language apparently endows the site with certain level of vibrancy.

• PHP’s written scripts are pretty instrumental in keeping track of the visitor’s activities on your site. Sending out emails to the subscribers, aiding users upload files or images to the site, and driving content on your site dynamically, using databases.

• Small business sites, can utilize PHP to obtain feed back from users on their products and services. The script even aids in creating a form which will allow customers in sending emails to you directly.

• Being a free open source language, the users need not shell out thousands of dollars in licensing fee to acquire PHP. Cost-savings has made PHP the much preferred language over competitors like Microsoft’s ASP.NET and Visual Basic.net and Sun Microsystems’ Java.

• Easy in installation. Moreover, PHP Programs have their base in C & C++ and finds similarity with C++ and C syntax and so it is even easy to learn.

• PHP does not put a load on servers. The code is optimized to make the server’s job easier.

• As much of the processing is moved to the server, collection and use of data becomes more convenient with PHP. Data can be easily stored in databases and used in new ways. Users have access to this centralized data. Web sites can be created by making use of the central reserve much more efficiently.

• PHP gives developers much more freedom to create light, feature rich web sites that reuse common elements while still being connected to extended data sources.

• One of PHP’s primary benefits is a lack of dependence on external programs to run the code. Media files like sound, video and flash require plug-ins to function. Some browsers have the necessary plug-ins pre-installed, but many of the browsers need to download the necessary software to view components of websites. PHP is executed exclusively by the server and therefore requires nothing from the end-user.

Using PHP for Web applicationsIn the beginning, Web pages were static – they just presented documents.Users went to Web sites to read information. Documents were linked togetherso that users could easily find the information they sought, but the Web pagesdidn’t change. Every user who arrived at a Web page saw the same thing.Soon Web page developers wanted to do more. They wanted to interact withvisitors, collect information from users, and provide Web pages that werecustomized for individuals. Several languages have developed that can beused to make Web sites dynamic. PHP is one of the most successful of theselanguages, evolving quickly to become more and more useful and rapidlygrowing in popularity.PHP is a server-side scripting language, which means that the scripts are executedon the  server (the computer where the Web site is located). This is different

Because PHP scripts execute on the server, PHP can dynamically create the HTML code that generates the Web page, which allows individual users to see customized Web pages. Web page visitors see the output from scripts, but not the scripts themselves. PHP has many features designed specifically for use in Web sites, including the following: Interact with HTML forms: PHP can display an HTML form and process the information that the user types in. Communicate with databases: PHP can interact with databases to store information from the user or retrieve information that is displayed to the user. Generate secure Web pages: PHP allows the developer to create secure Web pages that require users to enter a valid username and password before seeing the Web page content. PHP features make these and many other Web page tasks easy. PHP is only server-side, meaning it can’t interact directly with the user’s computer. That means PHP can’t initiate actions based on the status of the user’s computer, such as mouse actions or screen size. Therefore, PHP alone can’t produce some popular effects, such as navigation menus that drop down or change color. On the other hand, JavaScript, a client-side scripting language.

PHP-Finalizing Orders
When a user finishes adding items to his cart, he usually proceeds to a purchase. Finalizing an order requires several steps that include checking that sufficient inventory is available to complete the order, converting the shopping cart to an order, and deducting the wines sold from the inventory. These tasks require locking of the database and are examples of moderately complex query processing. The script order.3 shown in Example 12-1 performs these tasks.

The script works as follows:

It tests that the user is logged in and that the cart has contents. These tests should never fail, as the Make Purchase button is shown only when the user is viewing the cart, is logged in, and the cart has contents. If either test fails, an error message is registered, and the script redirects to the calling script.

The inventory, items, and orders tables are locked for writing, and the users and customer tables are locked for reading. The inventory, items, and orders tables are all updated in the purchasing process, and they must be locked because the inventory is first checked to ensure that sufficient quantities of wine are available and then later updated. Without locking, it is possible for another user to purchase the wine while this script is running, resulting in more wine being sold than is in stock. This is an example of the dirty read concurrency problem discussed in Chapter 6, and locking must be used to avoid the problem.

Each item in the cart is then processed, and the inventory is checked to ensure that enough wine is available. If no wine is available—the count( ) of the matching inventory rows is zero—an error message is registered. Similarly, if less wine is available than the user wants—the sum( ) of the on_hand quantity of the matching rows is less than the user’s cart qty—an error message is also registered. On error, the script also updates the user’s cart so that the quantity (qty) of wine in the user’s cart matches the quantity that is on_hand. In the case of an error, the script uses the function showWine( ) to show the user the details of the wine. This function opens its own connection to the DBMS so that the wine, wine_variety, winery, and grape_variety tables don’t need to be locked for reading in the order.

If the inventory checks succeed, the script proceeds to convert the user’s cart to be a customer’s order. This process is straightforward:

Determine the cust_id from the loginUsername session variable using the function getCustomerID( ).

Find the maximum order_id for this customer.

Update the orders and items rows by replacing the cust_id of -1 with the customer’s cust_id and the order_id with the next available order_id for this customer.

After the database has been updated, the cart is emptied using session_unregister( ) to remove the order_no session variable.

Having completed the order and checked the inventory, the script finishes the ordering process by reducing the inventory. This can never fail, since all required tables are locked, and you’ve checked that sufficient quantities are available. The process is similar to checking the cart: you iterate through each item and, for each one, you update the inventory. The inventories are processed from oldest to newest. Consider an example in which the user wants to purchase 24 bottles of a wine. There are two inventories of this wine: the first has 13 bottles and was added in May 2000; the second has 25 bottles and was added in September 2001. To satisfy the order, the oldest inventory of 13 bottles is emptied and deleted, and the second inventory is reduced by 11 bottles.

With the process complete, the tables are unlocked. If there are no errors, the script redirects to the shipping.1 script to confirm the order, and the cust_id and order_id are passed as GET method parameters. If there are errors, the user is returned to the cart view page.

Example 12-1. order.3 finalizes the user’s purchase
<?php
// This script finalizes a purchase
// It expects that a cart has contents and that the
// user is logged in

include ‘include.inc’;

set_error_handler(”errorHandler”);

// Check if a cart exists – this should never fail

In the IT enduser community, the idea of Open Source brings with it a plethora of elation as well as fear. Ask anyone who is an IBM AS/400 and they will tell you that they are stuck in their for life – at least until they decide to get out of what they put themselves into.

Yes, IBM AS/400 (rebranded as IBM System i in 2006 and subsequently replaced by the IBM Power System line) is a very stable platform. The many applications developed for it are rock solid, enterprise-class software that do what they are meant to do. Throughout its period of reincarnation (1988 to present), the hardware and software may have changed but IBM made sure the applications are transplanted. 

I am digressing so let me paraphrase one CIO comment about their AS/400 investment. “We are stuck and we know we are paying through the nose but we have no alternative today!”

Distributed Computing (DC) arose partly in response to the need to get out of the mainframe and mini-computer era of vendor lock-in. Little did we know that while DC hailed the arrival of an army of vendors offering competing and complementary systems, the liberation was partial – because many of the initial technologies created in support of DC are proprietary in nature. Sure they are able to talk to other vendor’s solutions but this is because application programming interface (API) were built to allow for some semblance of interoperability.

Enter Open Source. The idea that a program’s code is freely available to the end-user community to use and modify to suite a particular need. Can a software company survive giving away its software? Red Hat thinks so. In fact, within the Open Source community, Red Hat is a testament to the idea that you can give away copies of your software (even if it was originally conceived by someone else), make money and prosper.

SUN Microsystems is another company that is heavy into the Open Source momentum. But whereas RedHat is 100% open source, SUN still has technology that is proprietary – afterall, SUN started life in the proprietary world. It can be argued that JAVA was SUN’s first experiment in Open Source. Thankfully, the JAVA community thrives today despite competition.

As with all things, proven or otherwise, there are skeptics. In human nature, the biggest fear is always that of the unknown. For many enterprises whose businesses depend on the smooth running of mission-critical applications, the high price associated with proprietary hardware, middleware or operating systems, custom application, and availability of skilled resources is a bitter sweet pill that they’d readily swallow.

The adage that thrives in these environments is “better the devil you know”. Which validates what Tom Zack, general manager of sales for Asia Pacific at Red Hat recently said over lunch. “Open Source means free so I can’t get support.”

Although there are differences in how some Open Source software licenses are executed, by and large, people are free to use Open Source. You can modify an application created on Open Source and you are encouraged – not forced – to freely donate any enhancements you’ve made with the code. This is the nature of Open Source.

The problem becomes one of support. If I were to use an Open Source application, what support can I expect? This is where the conundrum lies. There is an adequate supply of help (a.k.a. community support) available on the Internet for most of the Open Source software that lives out there. The problem is sometimes there is more than one way to fix a problem. For companies that depend on software to run their business, would you be willing to try each of those fixes in the hopes of landing the right one? If you are a bank, you probably don’t want to risk losing your customers or explaining to a regulatory body why your application died while doing a routine bank deposit transaction.

There are also cases where companies, attracted by the very low, sometimes free, price tags that come with Open Source application, dive head on into the technology only to discover that they don’t have the internal skill sets needed to support the Open Source programs that were introduced. They will probably end up spending more money on Open Source than they would with proprietary software. Oops!

Zack believes that if the only reason why a company would switch to Open Source is to save on the acquisition cost of the software, then “they are missing the point! Open Source gives companies greater freedom to choose what technologies will work best for them,” said Zack.

And in some sense, this is true. If you are an Oracle, SAP or Microsoft user, ask yourself this question. “Do you ever feel locked-in to the platform you’ve chosen because (1) the closed system you purchased is purported to work best with software from the same vendor; (2) the vendor plays lip service to the notion of supporting other platforms but is quick to point a finger to the other party when something does not quite work out the way it should; or (3) you fear that introducing other systems to the homogeneous environment raises issues like risks and uncertainties – which is what FUD is all about? If you are, you may need to evaluate your understanding of Open Source and be more open minded about what others have to say.

The fight for Open Source continues and players from both sides are spending money to win the game.

The good news for vendors like Red Hat is that the financial crisis will force the hand of companies that find themselves with shrinking IT budgets, limited resources available, and a management that is more open to the idea of taking some risks in favor of long-term survival.

In the meantime, industry associations like FOSSBazaar, an HP-led Linux Foundation working group, are tasked with working to replace fear of open source with knowledge and best practices.

History has proven that knowledge, understanding, and common sense will eventually prevail. The Open Source community will gain grounds with each passing day. There will be setbacks but these will be more than offset by new developments and effort in the drive towards wider adoption of Open Source.

In the meantime, proprietary software vendors like Microsoft, Oracle and SAP will, in all likelihood, be quietly developing new versions of software, if not totally new business models, that will in some ways offset the threat of the Open Source movement.

These vendors will need to keep justifying their higher margins using the promise of ‘fair pricing practices’ to justify the high cost of not only licensing their software (yes, its licensing, you don’t own the software because the vendor owns the IP) and the maintenance/support fees that come with each solution.

As for companies like Red Hat that make their bread and butter on selling software and service by way of subscription, they have to be always on their toes. Open Source is a double edge sword. Yes, Red Hat’s prices are lower compared to Microsoft but then there is always someone who can offer software at cheaper prices – like free. The good and bad news is that there are more Red Hats out in the market than Microsofts. Which means that to keep customers, customer satisfaction must be high on the daily operating agenda of the software vendor.

So if your business is looking to try Open Source, Zack recommends trying the hard proven approach to anything new in IT: start small, get familiar with the kinks, evaluate the results, and make your move from there.

Sound advise to me!
