query string

corruption

I've seen this in practice but have no idea how to actually do it or how it works. url would look like www.someserver.com/index.php?page=about or something like that how does that work..do you store the pages in html on the database or php on a database
text files to fill the area or something. I think it would be something cool to learn if there are any good tutorials on it that would be great or just a start on how to get there.
thanks

ummm - what exactly is your question? what the query string does?

corruption

what it does and how it is implemented, how to store the file that it calls; php, html, database, flatfile etc?

index.php?foo=bar

calls the page index.php and sets the variable $foo to the value "bar".

so it is pretty much the same like having the following at the beginning of index.php:

$foo = "bar";

or more accurately

$_GET['foo'] = "bar";

the file it calls must be php-parsed. by default servers parse .php files (as long as a server and php is installled properly), but you may also change the settings in your server config so other file types are being parsed too.

an easy example to see how it works:

store a file test.php including the following code:

<?PHP
print "Welcome " . $user;
?>

now call it like
test.php?user=YOUR_NAME_HERE

the output should explain what it does...

corruption

so for example...i have the page index.php
in the beginning i would put

$get['aboutme'] = "aboutme.php"
$get['activities'] = "activities.php"

something like that and those other files are save in the root directory as aboutme.php and activities.php correct

also does it work in html files with php before the output...

i.e.
<? php
$_get['about'] = "aboutme.php"
etc

?>
<html>
some div or css to assign where aboutme.php is displayed?
</html>

i hate to ask so many questions
is there a place that i can look up how to do this, does any tutorial that you know of go this deep into the code?
