在Codeigniter中針對ID提取所有記錄

Question

當我從數據庫中檢索數據時，輸出如下

我想針對這些ID提取記錄，但是當我嘗試對每個ID進行控制時，它只給我1條記錄。這是我的代碼

//fetch all the posts relative to user in session
    $post_id['id'] = $this->message_model->get_post($id);
    echo '<pre>'; print_r($post_id['id']);die;
     foreach ($post_id['id'] as $key) {

        $post_id    =     $key['post_id'];
        $results['post_list'] = $this->Model_Frontend_Posts->get($post_id);
    }

當我打印$results['post_list']它只給我一條記錄

Answer 1

$post_id['id'] = $this->message_model->get_post($id);
 $array = array_column($post_id['id'], 'post_id'));
     foreach ($array as $value) {
        $results['post_list'] = $this->Model_Frontend_Posts->get($value);
    }

最好從參考http://php.net/manual/zh/function.array-column.php使用array_column

Answer 2

將其放在數組中，這樣它就不會在每個循環中都被覆蓋。 我想這應該解決-

$results['post_list'][] = $this->Model_Frontend_Posts->get($post_id);

代替

$results['post_list'] = $this->Model_Frontend_Posts->get($post_id);
