What Is PHP?

The full form of PHP is Hypertext PreProcessor and is a server-side scripting language. The PHP code can be combined with regular HTML tags and parsed on the server. The creator of PHP, Rasmus Lerdorf first displayed the language in the form of a Perl script . In 1997 it was adapted by Andi Gutmans and Zeev Suraski to use a C-written compiler. They completely reconstructed the original PHP into the web language that we know and use today.

Uses of PHP

It is used in the creation of dynamic web pages. Web developers like it because of its fast parsing and flexibility and versatility. PHP is a popular tool for managing a form's data after it is submitted and comes built in with many different interfaces and API's. It has database capability built into the language, the most common database being MySQL. Typically the PHP can connect to any SQL enabled database.

The Syntax of PHP is similar in structure to Perl and C where curly braces { } define blocks of code and semi-colons specify the end of a statement PHP is as easy to learn as Perl. It maintains all the traditional loops, if/else, and subroutines that are expected in a programming language. One difference between the two is that the code'?' is embedded in with the HTML; you could however, use a separate file. The PHP code is different from HTML code by use of the opening and closing tags. When it finds a PHP file, it tells the server to scan through for these tags, and execute the code in between them. The server recognizes a PHP enabled file by its extension, .php. These are essentially HTML files with PHP codes in them.

Getting Started

To start PHP requires a server with PHP installed and a simple ASCII text editor such as Notepad or VI, eMacs, Kate, etc. for a UNIX/Linux machine.

What are the problems faced by PHP?

It is case sensitive. For example if you name a variable $MyVar, you cannot call it as $myvar or $mYvAr. In case you forget to close your curly brackets, then it helps to indent lines inside the curly braces so that any missing braces can be spotted easily.

In the recent past, the Internet has become the prime means of media connection around the world. Aside from providing a fast and inexpensive means of imparting and extracting information, cyberspace has also redefined the very lifestyle of people around the world. From shopping to taking up courses, people have found immeasurable uses for the Internet.

No wonder then that everyone wants a space in cyber world. A website is the means of publishing personal or corporate information over the Internet. It is like a unique telephone number over a vast circuit of telephone lines; or better put, a unique address in the wide world of cyber space.

However, it is a well-known fact that not everybody knows how to create a website. A vast majority of Internet users who would like their very own web address in cyberspace do not have either the skills or the time to learn the intricacies of creating a website.

This is where an awb comes in handy. As the name indicates, an automatic website builder is an application or a group of applications that lets an individual who has no knowledge of underlying website software applications and languages involved build a website without sweat.

Unlike an HTML editor which merely facilitates in the creation of correct HTML scripts, an automatic builder provides the user with web page templates that are already built and can be modified by the user according to his or her preferences. Aside from pre-fabricated templates, some awb provide other important features as well. A number of automatic website builders have Shipping Cart feature that enables web visitors to shop for goods offered at the website. Still, other programs have built-in survey counters that can monitor the traffic of users who visited the website.

An automatic builder makes the process of putting the latest and most relevant information or content in a user's website quick and easy. Having the freshest content in a website means satisfied web visitors. This translates to higher traffic; therefore, improving a website's list ranking in search engines like Google.

Some websites come with a price. The range of prices may be as wide as a few bucks per month for subscription setting to more than a hundred dollars for one-time purchase arrangements. Others can be availed for free.

A purchased website builder provides premium features than a free program. A purchased program can come with unlimited number of website designs which could easily be a means to make money. By creating unique websites for friends and other customers, a user can easily earn additional income. Plus, this type of builder has tie-ups with other certified applications that can be enjoyed for free.

A free application, like the one commonly used for blog websites, has a limited number of website design concepts. There is a high probability that using this type of builder will be prone to pop-ups and third party piggyback advertisements. However, while the uniqueness or even the security of a website may be compromised, a free automatic website builder has zero cost.

Automatic website builders can be classified into to basic types; online and offline. An online builder enables users to edit the website they created using a web browser like Internet Explorer or Netscape. While an offline builder requires users to edit the site in a computer's local application before the edited website can be published. But no matter what type of automatic website builder application is used, the user is sure to have an efficient, effective and a fun way of building websites.

Not every site needs a site map, they can certainly be a good idea. Site maps provide a dual purpose: They provide search engine spiders easy access to all of your site pages and they provide site visitors easy access to all of your site pages. The difference is that search engines and visitors access your site map differently and therefore there are different methods that need to be applied to creating site map(s) that are friendly for both engines and search spiders.

Small sites typically don't need a site map so long as all pages are linked in the main navigation. Once you get into main and sub-navigation menu's then site maps are helpful in allowing search engines and visitors to quickly find anything they are looking for within just a couple of clicks. A single site map can be used for both purposes or multiple site maps can be created. Here we'll address creating site maps for spiders and humans separately.

Site Map For Spiders

.xml file

An .xml document should be added to your site's root directory containing links to all site pages. This .xml file should then be referenced should be compiled and placed into a proper .xml document which should be uploaded into the root directory.

Robots.txt file

With your .xml site map file in place you must then make it accessible to search spiders. Reference the site map in your robots.txt file by adding a line for sitemap: URL (example: sitemap: http://www.polepositionmarketing.com/sitemap.xml)

Keep current

Be sure that your .xml file is updated and uploaded frequently, or at least as often as pages are added or removed from your site. Large sites should implement an automated site map update monthly or even weekly or daily.

Site Map For Visitors

Navigation links

A site map designed for human visitors is just like any other website page. Link to the site map page should be included in the primary navigation or the site's global footer. Visitors should be able to find this link without too much searching.

Additional page links

Site map should also be linked from various pages within the site such as Help pages and your custom 404-redirect page. This helps point visitors to the site map as a quick and easy means to find what they need.

Overview

It's helpful to provide a short overview paragraph at the top of your site map page. This can be a nice introduction should someone land on this page directly from a search engine or elsewhere.

Heading and layout

The layout of the site map should present a clear visual hierarchal structure or your website. Both headings and sub-headings should be used above properly grouped links.

Text links & descriptions

Site map should primarily use textual links and page should not be cluttered with images or other distractions. It is also a good idea to provide an additional short description (provided there is room) for each link that allows the visitor to better understand where each link will take them.

Keep current

Be sure that your site map is updated and uploaded frequently, or at least as often as pages are added or removed from your site.

As I said above, not every site needs a site map. But those that do should be sure that the site map(s) they create are actually benefiting them. And the best way to do that is to make sure your site maps provide maximum usability for visitors and search engine spiders.
