如何用PHP自訂Excel的匯出及合併儲存格

這次跟大家聊聊j如何用PHP自訂Excel的匯出及合併儲存格，下面就是實戰案例，一起來看一下。

首先自訂匯出，我用的是一個下拉多選框的一個外掛程式，百度一下就可找到，為了樣式好看。

value值對應的是你資料庫中查出的欄位值，text對應的是你的表頭資訊。ok，然後我是通過GET把這倆個值傳到我們控制器的。

引入匯出類，這個就不多說。

然後就是查詢資料庫，把資料處理成一個二維數組，進行迴圈遍曆輸出在表格中

我的資料格式是1對多的關係，一個班主任對應多個班級，那麼我要在表格中合并這個班主任,$count是對班級的統計，當班主任

對應的班級數量>1時，才合并。

            $str=$_GET['str'];//勾選            $str2=$_GET['str2'];//表頭            $td_field=explode(',', $str2);//表頭            $field=explode(',', $str);//勾選            $objPHPExcel=new \PHPExcel();            $objPHPExcel->getProperties()->setCreator('http://www.jb51.NET')                ->setLastModifiedBy('http://www.jb51.Net')                ->setTitle('Office 2007 XLSX Document')                ->setSubject('Office 2007 XLSX Document')                ->setDescription('Document for Office 2007 XLSX, generated using PHP classes.')                ->setKeywords('office 2007 openxml php')                ->setCategory('Result file');            $objPHPExcel->setActiveSheetIndex(0)                ->setCellValue('A1',$td_field[0])                ->setCellValue('B1',$td_field[1])                ->setCellValue('C1',$td_field[2])                ->setCellValue('D1',$td_field[3])                ->setCellValue('E1',$td_field[4])                ->setCellValue('F1',$td_field[5])                ->setCellValue('G1',$td_field[6])                ->setCellValue('H1',$td_field[7])                ->setCellValue('I1',$td_field[8])                ->setCellValue('J1',$td_field[9])                ->setCellValue('K1',$td_field[10])                ->setCellValue('L1',$td_field[11])                ->setCellValue('M1',$td_field[12]);
