On NETTUTS.com today there's a tutorial (a screencast) that'll show you how to create excerpts for the posts in your blog. Their method could be applied to just about any PHP-based blog software out there since it uses base PHP functions and MySQL features.
Ever visited a blog, and noticed that each posting's overview only contained a hundred characters or so, which is then followed by 'œ'¦'? Ever wondered how to do that yourself? It's not quite as easy as you might think. What if character number 100 occurs in the middle of a word? Do you want to display half of a word on the page? Of course not. In this video tutorial, I'll show you how to compensate for this, as well as a host of other neat little things, like working with MySQL's LEFT() function, using PHP's strrpos, and substr, creating the beginning's of an actual blog, and more.
