tp5使用PHPexcel扩展导出excel表

1,使用composer安装phpexcel包:

composer require phpoffice/phpexcel

2,在控制器中创建方法:

(1)使用PHPexcel扩展。代码如下

 /**
     * 导出excel表格(默认格式)
     *
     * @param   array    $columName    第一行的列名称
     * @param   array    $list         二维数组
     * @param   string   $setTitle    sheet名称
     * @return  
     * @author  Tggui 
     */
    private function exportExcel1($columName, $list, $fileName='demo', $setTitle='Sheet1'){
 
       vendor('phpoffice.phpexcel.Classes.PHPexcel');
       vendor('phpoffice.phpexcel.Classes.PHPexcel.IOFactory');
 
        if ( empty($columName) || empty($list) ) {
            return '列名或者内容不能为空';
        }
        if ( count($list[0]) != count($columName) ) {
            return '列名跟数据的列不一致';
        }
        $fileName = iconv("utf-8", "gb2312", $fileName);
        //实例化PHPExcel类
        $PHPExcel    =    new \PHPExcel();
        //获得当前sheet对象
        $PHPSheet    =    $PHPExcel    ->    getActiveSheet();
        //定义sheet名称
        $PHPSheet    ->    setTitle($setTitle);
        
        //excel的列 这么多够用了吧?不够自个加 AA AB AC ……
        $letter        =    [
            'A','B','C','D','E','F','G','H','I','J','K','L','M',
            'N','O','P','Q','R','S','T','U','V','W','X','Y','Z'
        ];
        //把列名写入第1行 A1 B1 C1 ...
        for ($i=0; $i < count($list[0]); $i++) {
            //$letter[$i]1 = A1 B1 C1  $letter[$i] = 列1 列2 列3
            $PHPSheet->setCellValue("$letter[$i]1","$columName[$i]");
        }
        //内容第2行开始
        foreach ($list as $key => $val) {
            //array_values 把一维数组的键转为0 1 2 3 ..
            foreach (array_values($val) as $key2 => $val2) {
                //$letter[$key2].($key+2) = A2 B2 C2 ……
                $PHPSheet->setCellValue($letter[$key2].($key+2),$val2);
            }
        }
        //生成2007版本的xlsx
        $PHPWriter = \PHPExcel_IOFactory::createWriter($PHPExcel,'Excel2007');
        header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
        header('Content-Disposition: attachment;filename='.$fileName.'.xlsx');
        header('Cache-Control: max-age=0');
        $PHPWriter->save("php://output");
        exit;
    }

2),自定义函数,不使用PHPexcel扩展。代码如下:

/**
     * 导出excel表格
     *
     * @param   array    $columName    第一行的列名称
     * @param   array    $list         二维数组
     * @param   string   $setTitle    sheet名称
     * @return  
     * @author  Tggui 
     */
    public function  exportExcel($columName, $data, $fileName='demo', $setTitle='Sheet1'){
        $table = '';
        if(!empty($columName) && is_array($columName)){
            $table .= "";
            foreach($columNameas$key=>$value){
            $table .= "";
            }
            $table .= "";
        }
        $table .= "";
        if(!empty($data) && is_array($columName)){
            foreach($dataas$k=>$v){
                $table .= "";
                foreach($vas$vk=>$vv){
            $table .= "";
            }        
    
        $table .= "";
            }
        }
        $table .= "
{$value}
{$vv}
"; //通过header头控制输出excel表格 header("Pragma: public"); header("Expires: 0"); header("Cache-Control:must-revalidate, post-check=0, pre-check=0"); header("Content-Type:application/force-download"); header("Content-Type:application/vnd.ms-execl"); header("Content-Type:application/octet-stream"); header("Content-Type:application/download"); header('Content-Disposition:attachment;filename="'.$fileName.'.xls"'); header("Content-Transfer-Encoding:binary"); echo $table; } }

3,创建导出测试方法:

/**
 * @method   导出测试方法
 */
public function connectOrder()
  {
      //连接数据库获取数据
    $clt_db = Db::connect('clt_db');
    $data = $clt_db->name('admin')
          ->field('username,extension,email,tel')
          ->select();
    //第一行的列数据
    $header = array('用户名', '工号', '邮箱', '电话号码');
    
    //调用导出方法
    self::exportExcel1($header, $data, date('Y-m-d'));
  }
