I have a WP Query code like below to check if have post match all post_meta > get that post, else create new post, but the result always show me a post have only loaicua = cua-chinh and loaiphong = phong-khach and i don't know why.

Can someone point out the error in the code below? I will appreciate any help.

<?php
foreach( $meta_array as $meta ) { $i++;
    if (!isset($page_query_args[$meta['key']])) {
        $page_query_args[$meta['key']]['key'] = $meta['key'];
        $page_query_args[$meta['key']]['value'][] = $meta['value'];
        $page_query_args[$meta['key']]['type'] = 'CHAR';
        $page_query_args[$meta['key']]['compare'] = 'IN';
    } else {
        $page_query_args[$meta['key']]['value'][] = $meta['value'];
    }
    if( $i == sizeof( $meta_array ) ) {
        $page_query_args = array_values($page_query_args);
    }
}

if( sizeof( $meta_array ) > 1 ) {
    $page_query_args['relation'] = 'AND';
}

$page_query = new WP_Query(
    array(
        'post_type' => 'page',
        'orderby' => 'date',
        'order' => 'DESC',
        'meta_query' => $page_query_args,
    )
);

Output of $page_query_args
