在我看来，我如何在 foreach 中访问它？

foreach($data as $key => $row){
            $col[$row['user_id']][$row['loan_id']] = $this->db->where('loan_user_id', $row['user_id'])->where('loan_id', $row['coll_loan_id'])->get('loans')->result_array();
            $col[$row['user_id']][$row['loan_id']][$row['coll_id']] = $this->db->where('coll_loan_id', $row['loan_id'])->where('coll_user_id', $row['user_id'])->get('collectables')->result_array();

        }

你要迭代的数组在哪里

【解决方案1】：

在你的控制器中

$col = array();
foreach($data as $key => $row){
    // Simplified the where condition by using array in where object
    $user_id = $row['user_id'];
    $load_id = $row['loan_id'];
    $col[$user_id][$load_id] = $this->db->where(array('loan_user_id' => $user_id,'loan_id' => $row['coll_loan_id']))->get('loans')->result_array();
    $col[$user_id][$load_id][$row['coll_id']] = $this->db->where(array('coll_loan_id' => $row['loan_id'], 'coll_user_id' => $row['user_id']))->get('collectables')->result_array();

}
$this->load->view('view_name', array('view_data' => $col));

在查看文件中

// Loop here
echo '<pre>';print_r($view_data);
