Why not add an ORDER BY clause to the SQL statement? It should be much
faster to sort the records within PostgreSQL than within PHP.

I'd suggest building your SQL statement dynamically.
$sql = "SELECT * FROM table1 WHERE surname LIKE '$NAME%' ";
if ( $radio[1] == 1 ) { $sql .= 'ORDER BY last_name '; }
else if ( $radio[2] == 1 ) { $sql .= 'ORDER BY first_name '; }
Then if you're using checkboxes to allow the user to set the fields to
display, loop through the user inputted list and dynamically set the fields
to display. Unless you're using PHP's serialize() and session functions (or
a similar method) you're not going to be able to pass the query results from
page to page to sort anyway - you'll have to requery Postgre every time you
want to change the output on the page based on some user input.
