外部のWordpressから読み込んだ記事を別のWordpressに自動で投稿したいです

Aサイトから読み込んだ記事をBサイトに自動で投稿させたいです。

また、そのAサイトの記事を更新したらBサイトで自動生成された記事も更新されるようにしたいです。

今の段階でのソースです。
`
global $wpdb;
$results = $wpdb->get_results("
SELECT post_title 
FROM wp_posts
");

foreach ($results as $post) {
$page_exists = $post->post_title;
}


//その他DB接続設定
$another_db_user = 'user';
$another_db_pass = 'pass';
$another_db_name = 'name';
$another_db_host = 'localhost';
$another_tb_prefix = 'wp_';

$mydb = new wpdb($another_db_user,$another_db_pass,$another_db_name,$another_db_host);

$mydb->set_prefix($another_tb_prefix);

//一覧情報取得
$result = $mydb->get_results("
SELECT  
m0.post_title,  
m0.id,  
m0.post_name,
m0.guid  
FROM ( select post_title, id, guid, post_name from wp_posts where post_type = 'bio' AND post_status = 'publish'  ) AS m0

foreach ($result as $value) {

if( $value->post_title == $page_exists  ) {

//何もしない

}

else {
$my_access = Array(

'post_author' => '1',

'post_status' => 'publish',

}

**これだと記事は重複されて繰り返し自動投稿します。**
