Since 'single' functions cannot handle multi-column data, SQLite provides the alternative in the form of sqlite_fetch_all() for multi-column result sets. 

<?php
chdir(dirname(__FILE__)); // pres2 hack

$db = sqlite_open("./ip.db");
$res = sqlite_unbuffered_query(
    "SELECT ip_start, ip_end 
     FROM ip_ranges 
     WHERE country_code=(SELECT id FROM country_data WHERE country_name='NEW CALEDONIA')", $db);

echo '<pre>';
print_r(sqlite_fetch_all($res, SQLITE_ASSOC));
echo '</pre>';
?>
Output
