Ok, well, I'll give the generic answer then...
Your table should have an AUTO_INCREMENT id field. Maybe it's called PersonID or ID (I dunno 'cause you never posted the things I asked for.)
You'll have an SQL query like 'SELECT ...' or 'SELECT Name, Address, Phone, Details ...'. If it's the variant--if that field exists in your table--you can use something like:
echo "details.php?id=" . $rows['PersonID'];
On your details page, use the same query (or one specifying more table fields) and append something like:
$query = "SELECT ... WHERE PersonID = " . $_GET['id'];
to the query.
If you can't be more specific, I suggest you read the manual, there are many examples.
