That's something else we've been doing for decades that has a brand new name. Design patterns arn't new at all! In fact the big book of Design Patterns is was written twelve years ago! Well, 12 years ago is new to me and there are new books being published today. And, what I said above about Design Patterns, is what you said below. see: http://en.wikipedia.org/wiki/Design_pattern_%28computer_science%29 There's a surprisingly number of old techniques that have been given a new coat of paint and sold as the latest model. The key is to recognize them, perhaps I should coin a new name for that, maybe Concept Evolution, Process Inheritance, or Legacy Identification -- but, to really get it accepted, it has to be complicated enough to impress. :-) Thats what Design Patterns are about. Describe abstract solutions for object-oriented problems which dozens of programmers had already to solve and present them in a way each programmer understands and give them a name which everyone can understand. Its not to impress people with complicated ideas but to simplify the communication between programmers and give them hints how a problem could be solved. No, you missed my point -- many books written to simplify, don't. That's the reason some books are better than others for different audiences. Some books appear to have been written to impress peers rather than to teach. If you think different, that's OK, but that doesn't make my statement less true. tedd -- --- http://sperling.com http://ancientstones.com http://earthstones.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

http://myurl.co.uk/index.php?p=news
Can someone tell me
(i) how is this achived
index.php ---
?php
if ($_GET['p'] === 'news') {
include 'news.inc.php';
} else if ($_GET['p'] === 'latest') {
include 'latest.inc.php';
}
some how I doubt that this is the actual code they use.
(ii) what is the technique called
search for terms like 'front controller', 'request dispatcher'
(iii) does it have any real benefits apprt from looking a bit nifty
sometimes a modular cms (for example) can be extended and automatically
generate useful URLs by using a URL scheme such as this.

RE: [PHP] what's all the about then?
Do this. 1. Create a script called hello.php with the following content: ?php echo $_GET['string']; ? 2. Enter http://yoururl/hello.php?string=Hello 3. The page will say Hello The content after the ? will be treated as GET variables in the http request to the server. You can use this to change behavior of a script depending on what the GET variables values are. /Peter -Original Message- From: Ross [mailto:[EMAIL PROTECTED] Sent: Wednesday, August 30, 2006 7:10 PM To: php-general@lists.php.net Subject: [PHP] what's all the about then?
