Yeah, i know that your 1 Ghz webserver deals quickly with files of a few megabytes, but anyway it's better to use a database to deal with that data sizes. > >What do you need?

You have the PHP manual in HTML format, right?? > This thing of not > having to declare just makes me nuts... Naaah, i find that useful...

As you've read it... include() is *VERY* *FUNNY* in PHP for a C programmer as you... Let's make a couple of examples... I have a web site, and i want to put the same heading in every php page once parsed (i.e. i want the main title and some links in *every* page). How do i do that? I could read the file with fopen() and so, or i could do it the right way... using include()... Let's say that i have the file "title.php" that contains the HTML section of the page that includes the header part, and the uper part of every page (the title and links). To put it in a page, i just have to write include "title.php"; Simple huh? Second example, more difficult. I have a database, and i'm working with several database servers (i.e. my local server for testing, preview server in later development phase, and definitive server) (these are functions for mysql) Well, we have to connect to the database with one line of code: $connection=mysql_connect("server","user","password"); Well. Imagine i have to connect to the database in 10 or 15 PHP pages. And that it's possible for the database server to be changed at every moment. The right way to do this is making a "connect.php" file that contains only the upper line of code (within <? ?> of course). And in the real PHP page it should look as this: include "connect.php"; ... ... $query=mysql_query("select blahblah from blahblah where blahblah",$connection); You know, mysql_query needs the query string and the optional link identifier (connection identifier). Think for a moment that the link id is neccesary. What does that code? connect.php assigns to a variable named $connection the link id for the database, and without returning it or anything, $connection can be used outside from connect.php !!!!! See what i want to say with "include copy-pastes code"?? > >Well, they'll be that guys that program under micro$oft... get a person > >that programs PHP under unix, they all hate ASP! > > I hate ASP!
