저장된 번역은 다음과 같이 쌍으로 존재함.

select meta_id,post_id,meta_key from wp_postmeta;

|    1339 |     421 | searchsyn           |

/home/suapapa/wp-content/plugins/wp-multilingual/multilingual.php

$str = serialize(array(base64_encode(serialize(unserialize(serialize($translation))))));
...
$GLOBALS['wpdb']->query(
"INSERT INTO ".$GLOBALS['table_prefix'].
"postmeta (post_id,meta_value,meta_key) VALUES ('".$item['ID']."', '".$str ."', 'translations')"); #알수없게 인코딩된 데이타
$GLOBALS['wpdb']->query(

'".WP_Multilingual::SafeVar(serialize(unserialize(serialize($translation))))."', 'searchsyn')"); #한글토막들 (regex 패턴?)

translation 데이타는 아래와 같이 찾아서 복원함.

$translations = unserialize($item['meta_value']);
$translations = unserialize(base64_decode($translations[0]));
