One of the best ways by which you can receive or send payment over the internet is by using Paypal, and is considered to be an inexpensive way by which e-commerce transactions can be conducted. And if you are interested in this method, all you have to do is visit the Paypal website and set up a business account with them.

However, in using Paypal as a third party shopping cart you only have two options when a customer wants to make a payment, and they are:

Option #1: You can pass the entire list of shopping cart items and show detailed payment information.

Option #2: You can only pass a total.

The problem with Option #1 is that the customer will have to re-enter the details once more when using Paypal, which can cause the customer to bail out on the sale due to annoyance of this repetition. Moreover, it makes more sense that the customer’s detailed information remains with the merchant rather than with Paypal.

And even though the approach with Option #2 means that the customer will not obtain the order details along with the Paypal invoice but this can resolved by sending them an email with the details of their purchase.

And this is done by creating a PHP page that will provide the customer with a ‘Confirmation” screen just as soon as he or she is viewing order details and is ready to complete his or her purchase. The advantage of using PHP in this case is that it collects the information required for Paypal, and submits it automatically without the customer having to do so.

It was in the year 1995 that the world first witnessed the rise of USB technology, which was designed to replace a range of connectors at the back of PCs produced by computer companies everywhere. Since then, this simple technology has replaced serial and parallel ports to the point that you can barely find one or two of them on a computer these days.

With this kind of prominence, a slew of other products have also evolved which use these ports in order to provide access to external hardware that serve a slew of purposes ranging from modems to printers to digital cameras and so on.

Perhaps the most basic device that can be found today is the USB serial adapter, which converts a USB port into a serial port to be used for communication devices that need only a serial port and no other.

But when it comes to supporting storage devices, another device has been offered to users everywhere in the form of a USB IDE adapter since this is one of the most popular formats that are used by several storage devices.

If you look at any computer these days, you’ll find several USB ports as opposed to parallel or serial ports, and perhaps the simplicity of USB technology has been the reason for its popularity over the years.

Another interesting device is the video splitter, which is most useful when you show business presentations or multimedia displays requiring multiple visual streams. In being able to split the signal from your computer from two to eight screens, this makes what you display viewable by more than just one group of people located close to your computer.

USB technology is here to stay and will continue to evolve over the years as well.

The PHP Group has recently released an updated version of the web scripting language primarily to fix security issues as well as to provide application-based and server enhancements to its users. At least two of the five vulnerabilities considered to be critical by the US National Vulnerability Database have been fixed in the PHP version 5.3.6 while the others remain unclassified until now.

The first of which is a format string flaw in the phar extension which could allow a denial of service condition or a remote code execution while the second flaw, the shared memory read functionality which if exploited could also lead to a denial of service condition while also giving access to sensitive areas of system memory as well.

The other fixes included high values for precision INI settings, ZIP archive handling and the reading of EXIF data, and which were all discussed by senior security advisor from Sophos Canada, Chester Wisniewski in a blog post.

The importance of updating your PHP at the earliest, if you do use PHP code for you website, was also considered to be an important task for users that would contain these fixes, and thus alleviate any security issues that might arise in the future.

While Windows users could download these updated from www.php.net, LINUX users would soon gain access to these updates from RSN (Real Soon Now) from your distributions’ update repositories.
