lalnamar Posted January 7, 2007 Share Posted January 7, 2007 I noticed that when i visit facebook (or many other sites, for that matter), i get a link that terminates with .php?id=(number)example:http://ufl.facebook.com/profile.php?id=1234567Why does the url terminate that way? What i'm trying to figure out is how exactly sites like facebook/myspace store the user information. Is it stored in a database and retrieved every time the user's information is requested? Is the .php?id part like a session id, or what? Quote Link to comment Share on other sites More sharing options...
Jessica Posted January 7, 2007 Share Posted January 7, 2007 Variables stored in the URL are in the array $_GET. The id is the number of the profile. It is likely in a database and pulled out (from a cached version for the larger ones) each time.That has nothing to do with sessions.

DarkendSoul Posted January 7, 2007 Share Posted January 7, 2007 I believe that this retrieves the information each time the page is requested... This uses the value set in the URL ($_GET['id']) and requests the information from the database and then outputs (if any) the information.The code could look something like this;[code]$user_info = mysql_select("SELECT * FROM users WHERE id = '{$_GET['id']}'");[/code]if that helps you any.
