首先引入excel類，用的TP框架

use think\PHPExcel;

#建立物件

 $objPHPExcel = new \PHPExcel();

顯示錯誤資訊

error_reporting(E_ALL);

設定標題之類屬性

$objPHPExcel->getProperties()->setCreator("這磚有點沉")
   ->setLastModifiedBy("這磚有點沉")
   ->setTitle("資料EXCEL匯出")
   ->setSubject("資料EXCEL匯出")
   ->setDescription("匯出資料")
   
 
->setKeywords("excel")
   ->setCategory("result file");

設定表頭(自行加粗等)

$objPHPExcel->getActiveSheet()->setCellValue('A1', '時間');
$objPHPExcel->getActiveSheet()->setCellValue('B1', '進線人數');
$objPHPExcel->getActiveSheet()->setCellValue('C1', '註冊人數');
$objPHPExcel->getActiveSheet()->setCellValue('D1', '註冊比');
 
$objPHPExcel->getActiveSheet()->setCellValue('E1', '簽約人數');
$objPHPExcel->getActiveSheet()->setCellValue('F1', '成單比');

#表頭合併並加粗

$objPHPExcel->getActiveSheet()->mergeCells("A1:F1");//合併
$objPHPExcel->getActiveSheet()->setCellValue("內容");//插入資料
$objPHPExcel->getActiveSheet()->getStyle('A1')->getFont()->setBold(true
 
);//加粗

#合併示例：

$objPHPExcel->getActiveSheet()->mergeCells('A1:F1');
$objPHPExcel->getActiveSheet()->mergeCells('A2:F2');
$objPHPExcel->getActiveSheet()->mergeCells('A6:F6');
$objPHPExcel->getActiveSheet()->mergeCells('A11:B11');

#字型與樣式

$objPHPExcel->getActiveSheet()->getDefaultStyle()->getFont()->setSize(12);//字型大小
$objPHPExcel->getActiveSheet()->getStyle('A1:F1')->getFont()->setBold(false);//是否加粗
$objPHPExcel->getActiveSheet()->getStyle('A1')->getFont()->setBold(true);//是是否加粗
$objPHPExcel->getActiveSheet()->getStyle('A1')->getFont()->setSize(12);//第一行字型大小

#設定單元格行高

$objPHPExcel->getActiveSheet()->getDefaultRowDimension()->setRowHeight(20);//設定預設行高
$objPHPExcel->getActiveSheet()->getRowDimension('1')->setRowHeight(20);//設定第一行行高

#設定單元格寬度

$objPHPExcel->getActiveSheet()->getColumnDimension('A')->setWidth(20);//設定A列寬度

#設定垂直居中

$objPHPExcel->getActiveSheet()->getStyle('A1')->getAlignment()->setVertical(PHPExcel_Style_Alignment::VERTICAL_CENTER);
$objPHPExcel->getActiveSheet()->getStyle('A2:F2')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);

#設定水平居中

$objPHPExcel->getActiveSheet()->getStyle('A1')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
$objPHPExcel->getActiveSheet()->getStyle('A1:F3')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);

#設定左對齊

$objPHPExcel->getActiveSheet()->getStyle('A1')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_LEFT);

插入資料

$objPHPExcel->setActiveSheetIndex(0)
                ->setCellValue('A1', $data['a'])
                ->setCellValue('B1', $data['b'])
                ->setCellValue('C1', $data['c'])
                ->setCellValue('D1', $data['d']);

設定sheet頁簽名稱

$objPHPExcel->getActiveSheet()->setTitle('資料統計-1');

將活動工作表索引設定為第一個工作表，以便Excel將其作為第一個工作表開啟

$objPHPExcel->setActiveSheetIndex(0);

設定輸出

$filename = '資料統計-' . $t;
//清空緩衝區並關閉輸出緩衝
ob_end_clean();

header("Content-Type:application/force-download");
header("Content-Type:application/vnd.ms-excel");
header('Content-Disposition:attachment;filename="'.$filename.'"');
header("Content-Type:application/octet-stream");
header("Content-Type:application/download");
header("Pragma: no-cache");

$objWriter = \PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->save('php://output');
exit;
