Question

我正在尝试将json编码的数据放入json文件中以便在事件日历中显示它们。我正在使用php codeigniter framework.I只是想知道除了我使用的方法之外是否还有其他任何方法。因为它不起作用。但当我回显它显示的json_encode数据时。但我想将它们写入一个单独的文件调用events.json。

提前致谢。

模型

function get_all_reservations_for_calendar(){
        $this->db->select('reservations.date,reservations.time,reservations.hall');
        $this->db->from('reservations');
        $this->db->where('is_deleted', '0');
        $query = $this->db->get();
        return $query->result();
    }

function index() {
        $reservation_service = new Reservation_service();
        $output['calendar_results'] = $reservation_service->get_all_reservations_for_calendar();
        $partials = array('content' => 'dashboard/dashboard_view');
        $this->template->load('template/main_template', $partials, $output);
    }

您可以使用 file_put_contents（）;

来存储文件数据

<?php
    //write to json file
     $jsonEvents=json_encode($calendar_results);
     file_put_contents('events.json',$jsonEvents);
    ?>

如何将json编码数据写入json文件？
