Using URL for new pages

nloding · July 5th, 2006, 05:40 PM

The subject doesn't quite describe what I want to do. Let me preface this with: I'm absolutely, 100% brand new at PHP -- this is for my first PHP script.

I see a lot of sites having, say, a news article on the main page, and having the URL be something like this:

http://domain.com/index.php?newsid=5

And that loads an entire new main page, with the menu, header, and footer, or what have you, remaining the same of course.

Is there an advantage to doing things this way? Why?

How does that code work? Is there an example code out there??

THANKS!!

I guess I'll bump this up the forum a bit.

I now see the advantages (less coding by far). But, being new, I'm having a hard time getting the code quite right. Is there a clean example that I can look at somewhere? I've done some googling but haven't found quite what I'm looking for.

Hi,

I'll try to explain the situation with the url.
In this example the file that is requested is index.php.
The variable changes(newsid=1)

The content on the page is partly static wich always has the same values like the layout banner etc.
And partly dynamic. When the newsid varable changes the content changes. The dynamic information can be retrieved externaly like a database.

Ill give you an example

save this file as index.php

Code:

<html>
<head></head>
<body>
<h1>this text is static and remains the same<h1>

<?php 
if (isset($_GET["id"])){
  echo ("this is an dynamic id:<br />".$_GET["id"]); 
}
else{
  echo("now enter index.php?id=1");
}
?>
</body>
<html>

All the dynamic info is generated within the <??> tags
This way you only use one page for more data. This can be effiecent for news pages forums and guestbooks.
