Did you know that your css code could be slowing down your website? Did you also know that there is a free solution out there that can help you optimize or reformat your css code for speed and readability? This article is going to explain the benefits of optimizing your css code and the reasons why all web designers should be doing it. First we need to take into account the 2 reasons why you would want to reformat your css: readability and optimization.

Readability

Having nicely formatted css that easily readable is very helpful when you are developing a site. Most of us (me included) can get pretty sloppy when in a hurry to develop code, and a formatter can really help out to make it more readable.

On development teams where both Macs and PCs are used, sometimes line breaks are not read correctly across platforms and your css can end up all on one line. A formatter can help get your code looking pretty again.

Optimization

The opposite of readability is optimization. One problem with CSS is that it can get pretty file-size heavy when designing with it - especially on complex layouts. Optimizing your CSS will strip out all unnecessary characters and leave your CSS lean and mean.

Optimizing css is great to do once you've finished your site and don't plan to work on the design very much anymore.

The css formatter is a great tool because it can do both! You can format for readability while you are designing, optimize when you go live, and reformat it for readability if you ever need to work on it again. It's really a 'win win' thing to do.

I've done quite a bit of research into web analytics lately, and I have found a couple of things. Google analytics Is a great tool, but it cannot be the only tool an organization relies on. Because it is a purely JavaScript based, it is unable to catch browsers that do not have JavaScript enabled, this includes the search engine robots, some hand held devices, as well as a percent of users that manually turn this off. That being said we need a tool to parse the log files from the server and to give us information about these users, as well as providing us with "on demand" stats where as Google's stats are next day. The server logs also contain a wealth of other information that we are collecting automatically, so we might as well take advantage of it.

I have come to the conclusion that we need to use Google Analytics but we also need a tool that reads the server logs. There are quite a variety of tools that would fill this need. Google recently purchased Urchin who's web analysis product runs Google analytics, costs about $3k and will work with the Google Mini, Urchin also gives the ability to read logs from server software other than IIS (like apache, the software used for open source applications) .

Urchin will be releasing another version shortly, and this will be the first release since the Google buyout. Another option is WebTrends Analytics it costs about $4k. It Like Urchin will read both IIS and Apache logs, and has a web interface for users. The last product is NetTracker, it runs about $4k for the software, and another grand for support. it was recently bought out by Unica. The administration of netTracker is not the smoothest, and the support seems to have declined on quality since the buy out.

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.
