Can you make a page that displays "Hello, <USER>!" when <USER> comes
from the query string?

Suppose I go to http://www.yourserver.com/hello.php?user=Pedro
The "hello.php" script would be something like

<?php
if ((isset($_GET['user'])) && ($_GET['user'] != '')) {
echo "Hello, {$_GET['user']}!";
} else {
echo "Hello, anonymous!";
}
?>

It's just about the same thing when you want to use data from the query
string for database selection/sort. You just need to get the data and
incorporate it in the SQL commands (*after validating the data*).
