thinkphp框架excel导出

首先需在框架安装phpExcel

将以下代码复制到框架

    public static function run($param, $title, $putArr, $fieldArr)
    {
        $phpexcel = new \PHPExcel();
        //获取当前工作表
        $phpexcel->setActiveSheetIndex(0);
        //设置工作表名称
        $phpexcel->getActiveSheet()->setTitle($title);
        //设置列宽
        $charactors = array('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');
        //计算导出列数
        $count = count($putArr);
        $count != count($fieldArr) ? exit('导出字段有误') : '';
        $copy = [];
        for ($i = 0; $i < $count; $i++) {
            if (isset($charactors[$i])) {
                $l = $charactors[$i];
            } else {
                $k = intval($i / $count) - 1;
                $last = $i % $count;
                $l = $charactors[$k] . $charactors[$last];
            }
            $copy[] = $l;
            //设置列宽
            $phpexcel->getActiveSheet()->getColumnDimension($l)->setWidth(16);
            //设置表头
            $tl = $l . '1';
            $tltitle = $putArr[$i];
            $phpexcel->getActiveSheet()->setCellValue($tl, $tltitle);
        }
        //将需要导出的数组循环放入excel
        foreach ($param as $key => $value) {
            $key += 2;
            for ($i = 0; $i < $count; $i++) {
                $phpexcel->getActiveSheet()->setCellValue($copy[$i] . $key, $value[$fieldArr[$i]]);
            }
        }
        $sheet = time() . '.xlsx';
        (new \PHPExcel_Writer_Excel2007($phpexcel))->save(SAVE_PATH . $sheet);

        return '/upload/' . $sheet;
    }

调用此方法

//excel的表头，第一行
$putArr = ['编号','名称','类型','用户名'];
//对应的数组的键名 例：如下

$array = [

   [
      'id' => 1,
      'name' => 'xxx',
      'cate' => '老人',
      'username' => '张三',
   ],
   [
      'id' => 2,
      'name' => 'xxxx',
      'cate' => '老年人',
      'username' => '李四',
   ]
];

$fieldArr = ['id','name','cate','username']; 
//返回文件地址
$path = self::run($array, '文件名称', $putArr, $fieldArr);

根据类似的参数调用此方法，文件将保存到服务器，下载即可
