index.php?id=1 --> Q: How is this done?

Hi,

I'm new PHP code. And I've seen pages with following address -- ...index.php?id=1.

Q: How is this done?
Q: Are they using ISSET method? ...defining a variable with include file?

For example, this web site utilizes this method.

I would like a link in my index.php file, once clicked, to display additional content using the id=1 method...

Thankx in advance,
Arthur

something like that is usually generated from a database

PHP Code:


		
			
 $strQuery = mysql_query("select * from table");



while($row = mysql_fetch_array($strQuery))

{



echo "<a href='page.php?id={$row['id']}'>Link</a><br>";



}

That would print a list of links, each with there own unique ids

then to retrive that value, you would use the following code on page.php

PHP Code:


		
			
echo $_GET['id'];

or you could use that id as a index to query the database and get the selected information

PHP Code:


		
			
 $strQuery = mysql_query("select * from table where id = '{$_GET['id']}'");

it is possible that it is not being fetched from a db. example: index.php?id=about could be including the /content/about.php file into the template (if they are using a system of some sort)
