单个数组中的PHP Marge数组

所有

我正在使用这个foreach循环

foreach ($entries as $entry)
{
    global $wpdb;
    //$pname = $wpdb->get_var("SELECT meta_value FROM wp_frm_item_metas WHERE (field_id=228 && item_id=$entry->id) OR (field_id=301 && item_id=$entry->id) OR (field_id=120 && item_id=$entry->id)");
    $pname1 = $wpdb->get_results("SELECT id FROM wp_frm_item_metas WHERE (field_id=(SELECT id FROM wp_frm_fields WHERE field_key ='$field_key') && item_id=$entry->id)");
    echo "<pre>";
    print_r($pname1);
    echo "</pre>";
}

其结果是

Array
(
    [0] => stdClass Object
        (
            [id] => 984
        )
)
Array
(
    [0] => stdClass Object
        (
            [id] => 1047
        )
)
Array
(
    [0] => stdClass Object
        (
            [id] => 1077
        )
)

我想把它排列成单个数组。我试过这个。。。。

$genreArray=array();
foreach ($entries as $entry)
{
    global $wpdb;
    //$pname = $wpdb->get_var("SELECT meta_value FROM wp_frm_item_metas WHERE (field_id=228 && item_id=$entry->id) OR (field_id=301 && item_id=$entry->id) OR (field_id=120 && item_id=$entry->id)");
    $pname1 = $wpdb->get_results("SELECT id FROM wp_frm_item_metas WHERE (field_id=(SELECT id FROM wp_frm_fields WHERE field_key ='$field_key') && item_id=$entry->id)");
    $result = array_merge_recursive($genreArray, $pname1);         
}

但是，它只显示了数组的最后一个值。
