[SOLVED] A php file question

[forumnz]

what does this mean when a certain website has used this for each page

www.thisisanexample.com/?id=10&cat=2
www.thisisanexample.com/?id=3&cat=6

all of the pages has this... what has the person done to do this?

They could be using a mySQL database or just files.

Basically if they used a mysql database it would be something like:

[code]
$id = $_GET['id'];
$cat = $_GET['cat'];

if(!isset($id)){
$id = 1;
}
if(!isset($cat)){
$cat = 1;
}

$sql = "SELECT * FROM `pages` WHERE `pageid` =$id AND `cat` =$cat";
$res = mysql_query($sql) or die(mysql_error());
$row = mysql_fetch_assoc($res);

echo "page title: $row[title]<br>author: $row[author]<br><br>\n";
echo "contents: $row[pagecontents]";
[/code]

Thanks,

Where can I get a tutorial on this?

I think that simple example is probably as good as you'll get, its not really a huge subject.

[forumnz]

What would you call it?

[trq]

Passing variables via url.

It's using the $_GET variable... So research $_GET and maybe $_POST a little and then look up some php and mysql interaction stuff.  You should be able to figure it out from that :p
