PHP w/ MySQL and a "?"

Hey all, I am very new at PHP and I was wondering something. I know this is probably really basic. I setup a database in MySQL, I can connect and then pull data. This is my code: <? $server="localhost"; $username="nurck"; $password="------"; $database="------"; $table="-----"; @mysql_connect($server, $username, $password) or die("Connection"); @mysql_select_db($database) or die("Database"); $Result=mysql_query("SELECT * FROM $table"); while($row = mysql_fetch_array($Result)) { $id = $row["ID"]; $title = $row["title"]; echo "<font face=arial size=2>$id $title</font><br>"; } ?> Now, that displays all the data in the table. What I want to do is, in the address bar of IE or NN, have someone type in "www.whatever.com/hardware.php3?id=1" and have it send out just that row data, not the entire table. Like how Zend or other sites are setup using a database. Thanks for any help! Jay Stauffer
