懂php的高手或者玩wordpress的朋友前来帮忙，修改下代码

global $wpdb;
$post_datetimes = $wpdb->get_row($wpdb->prepare("SELECT YEAR(min(post_date_gmt)) AS firstyear, YEAR(max(post_date_gmt)) AS lastyear FROM $wpdb->posts WHERE post_date_gmt > 1970"));
if ($post_datetimes) {
$firstpost_year = $post_datetimes->firstyear;
$lastpost_year = $post_datetimes->lastyear;

$copyright = __('Copyright © ', 'elegantbox') . $firstpost_year;
if($firstpost_year != $lastpost_year) {
$copyright .= '-'. $lastpost_year;
}
$copyright .= ' ';

echo $copyright;
bloginfo('name');
}
printf(__(' | Powered by WordPress', 'elegantbox'), 'http://wordpress.org/');
printf(__(' | Theme by NeoEase', 'elegantbox'), 'http://www.neoease.com/');
