SQLite also supports query chaining that can be used to execute multiple queries via a single PHP function call. 

<?php
$query_str = ''; // init query storage string
while (($row = fgetcsv($fp, 4096))) {
    /* same old code ... */

    // append query to query list
    $query_str .= "INSERT INTO ip_ranges
        (ip_start, ip_end, country_code)
        VALUES({$row[0]}, {$row[1]}, {$country_id});";
}
// execute all inserts in one go
sqlite_query($query_str, sqlite_r);
?>
