In August 2008 I made a quick review of 50 plugins (part 1, part 2) and was really surprised by the number of coders who ship plugins with barely readable code. Working, even clever, but ugly code.
Making clean sources is not a useless mania of a compulsive obsessive geek, it’s truly a requisite for maintainable code. It won’t make your code good — just better.
For less experienced coders here are a few rules of thumb I try to follow. That’s just my word and my coding habits, nothing is to be considered as the definitive best practice, but I hope this will make anyway a good pointer for novices.

Short intro for readers who don’t follow me or this blog’s feed: I’ve been a judge in the annual WordPress Plugin Competition, and as such I have reviewed a number of plugins. Read more about this.

Some legacy parts of the WordPress code structure for PHP markup are inconsistent in their style. WordPress is working to gradually improve this by helping users maintain a consistent style so the code can remain clean and easy to read at a glance.
I wanted to write a plugin and came across an excellent site by Ronald Huereca that gives you good start on wordpress plugin. He gives a pdf down loadable file for wordpress plugn too.
Advanced Excerpt
This plugin adds several improvements to WordPress’ default way of creating excerpts.
1. It can keep HTML markup in the excerpt (and you get to choose which tags are included)
2. It trims the excerpt to a given length using either character count or word count
3. You can customise the excerpt length and the ellipsis character that will be used when trimming
4. The excerpt length is real (everything belonging to HTML tags is not counted)
5. Possibility to ignore custom excerpts and use the generated one instead
6. Theme developers can use the_advanced_excerpt() for even more control (see the FAQ)
Most WordPress plugins out there are simple things, fixing or changing one thing at a time. But there are also examples of more complex things, like e-commerce and banner management, advanced anti-SPAM control, more flexible content and user management, etc. One of the common things between those “advanced” plugins is that they almost always provide a user with a way to configure them – a screen with options.
WordPress, as most other modern content management systems, is a very database-centric application. It keeps all information in the database – blog settings, posts, comments, links, users, etc. Therefor it is important to understand how the database is organized, what types of data is stored there, and how different things are linked to each other.
