### Yii使用PhpSpreadsHeet 生成 Excel 和导入 Excel 前后端分离版和未分离版 ###

前提下载**PhpSpreadsHeet**依赖 ：

composer require phpoffice/phpspreadsheet

### 1.开始正题： ###

#### 1.1 这里使用这个数据库 检测工具表： ####

DROP TABLE IF EXISTS `test_tool`;
    CREATE TABLE `test_tool` (
      `id` int(11) NOT NULL AUTO_INCREMENT COMMENT '检测工具id',
      `tool_number` varchar(50) NOT NULL COMMENT '工具编号',

    ) ENGINE=InnoDB AUTO_INCREMENT=15 DEFAULT CHARSET=utf8 ROW_FORMAT=DYNAMIC;
    
    INSERT INTO `test_tool` VALUES ('1', '', '弛度观测仪', null, '1', '7', '1', '剪指甲', '全部', null, null, null, '使用方便', '2020-05-06 17:35:44', '2020-05-20 10:05:34', '/uploads/5ec4906e2e768_login_bg.jpg', null, null);

#### 1.3访问url 我本机是具体看你们自己的: ####

http://localhost/yii-excal/basic/web/index.php?r=exit/samples

就会下载这个 **无忧巡检工具列表.xlsx**

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlbmc3NA_size_16_color_FFFFFF_t_70]  
这里面的数据就是来自数据库，具体看我上面的代码。

#### 1.4 创建其他有导入和导出的页面方式。 ####

##### 1.4.2 创建TestController #####

##### 1.4.3 创建UploadForm 因为使用到了文件上传 #####

<?php
    
    
    namespace app\models;
    
    
    class UploadForm extends \yii\base\Model
    { 
    
        /** * @var */
        public $file;
    
        /** * @return array the validation rules. */
        public function rules()
        { 
            return [
                [['file'], 'file'],
            ];
        }
    }

##### 1.4.4 创建视图 viwes/test/ index.php #####

<?php
    use yii\bootstrap\ActiveForm;
    ?>
    
    
    <h2>导入表格</h2>
    <?php $form = ActiveForm::begin(['options' => ['enctype' => 'multipart/form-data'],'action' => ['import_excel_data'],'method'=>'post']) ?>
    
    <?= $form->field($file, 'file')->fileInput() ?>
    
    <button>导入表格</button>
    
    <?php ActiveForm::end() ?>
    
    <a  href="index.php?r=test/export_excel_data">下载表格</a>

完成以上就是可以访问：

http://localhost/yii-excal/basic/web/index.php?r=test/index

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlbmc3NA_size_16_color_FFFFFF_t_70 1]  
就可以完成导入和导出。

#### 1.5创建前后端分离的api方式： ####

使用导入前下载一个模板 然后再模板中输入 对应的数据 就可以说进行导入：
