Planning importance

Even if you’re already a professional programmer familiar with PHP, we encourage you to read the following sections, as they cover the basics for successful development. If you’re already familiar with the discussed topics, take the time to browse through the text anyway; you might discover new  information—new views of problems, new approaches, new solutions. The more you know about approaching different aspects of your future projects, the better you’ll be at nailing down the critical fragments and handling them in a superior way. Many of the following sections also discuss topics that are more questions of belief than commonly accepted rules. We’d like you to trust us as professional developers and rely on our experience before abandoning the content—it will pay later on. 02 0997 CH01  6/16/00  7:26 AM  Page 45 The Importance of Planning Before diving into PHP-specific issues, let’s start from a wider point of view. Some issues apply to application development in general, regardless of which language you’re using and on what platform you’re developing. When working on a professional project, it’s very important that you think about what you’re doing. Know your enemy—never underestimate him. Although your project isn’t really an enemy, the point still applies. Know all your project’s specifications, its target platform(s), its users, and never underestimate the significance of small problems that you haven’t evaluated completely before moving on to other topics.
Judging from our experience, planning takes at least 50% of the development time; the bigger the project, the more thoroughly you should develop its outlines.This principle applies to contacting your customers and working closely with them on defining an overall project outline, as well as talking with your developers about defining a coding outline.The less effort you spend on consistency and maintainability, the sooner you’ll run into problems when reopening old files and trying to fix bugs or
add new features.

ASP security

 Defense in Depth
Never rely on a single point of defense. Your application is often the last layer between an attacker
and back  -end systems such as a database or a fi le server, which, in turn, may be connected to a
corporate network. If your application is hacked, then these systems may be exposed to the attacker.
By using several layers of defensive techniques in your application such as input validation, secure
SQL construction, and proper authentication and authorization, your application will be more
resilient against attack.
  Never Trust Input
As you discovered in the example attack earlier in this chapter, a simple change to an input into the
application may result in a security breach. Input is everything that comes into your application
during run  -time — user data entry, the click of a button, data loaded from a database or remote
system, XML fi  les, anything you cannot know about at the time your application is compiled.
Every single piece of input should be validated and proved correct before you process it. If invalid
input is sent to your application, then your application must cope with it correctly, and not crash or
otherwise act upon it.

Goals of My business

Most likely, the fundamental goal of your business, when you get down to the bottom of it, is to make money by selling a product or service. However, there may be nuances to even such a straightforward goal as this. And there are a whole host of other possible goals and subgoals that your business is likely to have. Perhaps yours is a large company with branding as an important long-term goal.
Maybe your company wants to make money with certain products but is willing to take a loss in other areas. Maybe you are starting up with investor backing and do not need to turn a profit for years. Perhaps you are a nonprofit, with a goal to improve the world and inspire others to do the same. Whatever way you’re leaning, your business goals will affect your SEO campaign strategy. For instance, consider the fictional situation of Jason, a founding partner at Babyfuzzkin, a company selling unique, high-end baby clothes. This business makes its money directly through online sales. It’s a small operation, so there is a limit to how many orders the business can handle. The Babyfuzzkin fantasy would be a steady flow of, say, 100 orders per month. But there is more to the story: Eventually, the partners 87531c01.qxd  4/26/06  7:56 PM

Add keyword but don't overdo it

The first and foremost thing to be taken into consideration while writing an article which has to be submitted in the Internet is to make sure that there are enough keywords and phrases to link the article to your website and to show up in the search results. The use of keyword suggestion tools comes handy for this. A 2-4% ratio of keywords is good to occur in an article. That means that, if you are writing an article of 500 words, try to have your keyword appear at least 8 to 10 times. Keywords are the keys that open the gates for the traffic to enter your website. The more keywords you include in the article, the higher it will show up in the search engine results.  
  
However, “too much of anything is good for nothing” and so, if you use your keywords too much, than  your article will be viewed as spam.

The optimum keyword ratio is 2-4% of total words in the article. Anything more than that will make the article difficult to read and will also destroy the professionalism of the article.
