1,常见问题
由于PHPExcel没有命名空间,因此导入是个问题,解决方案之一如下:
将PHPExcel放在vendor下边,在Class类名引入头部
require_once '../vendor/phpoffice/phpexcel/Classes/PHPExcel.php';
2,读取Excel的内容
public function readPriceXsl($xsl_path)
{
$inputFileName = substr($xsl_path,1); // 移除路径的/
// $inputFileType = \PHPExcel_IOFactory::identify($inputFileName); // 此处是phpspreadsheet的使用方法
// $objReader = \PHPExcel_IOFactory::createReader($inputFileType); // 此处是phpspreadsheet的使用方法
$inputFileType = IOFactory::identify($inputFileName);
$objReader = IOFactory::createReader($inputFileType);
$objPHPExcel = $objReader->load($inputFileName);
$h1 = $objPHPExcel->getSheet(0)->getCell('H1')->getFormattedValue();
$data = [
'h1' => $h1, //版本
];
return $data;
}
说明:
getSheet(0)
读取第一个sheet表格
getActiveSheet()
读取第当前活跃的sheet表格
getValue()
获取单元格的Text文本(公式本身)
getFormattedValue()
获取单元格的的值(公式计算后的值)
3,将内容写入Excel
public function savePath1TOPath3($path1,$ver_id)
{
// 读取
$data = $this->readNewPriceXsl($path1);
$path = 'uploads/sample.xls'; // 读取模板,替换值
$inputFileName = $path;
// 此处使用的是phpspreadsheet
$inputFileType = \PHPExcel_IOFactory::identify($inputFileName);
$objReader = \PHPExcel_IOFactory::createReader($inputFileType);
$objPHPExcel = $objReader->load($inputFileName);
$objPHPExcel->getActiveSheet()->setCellValue('A2',$data['a2']);
$objWriter = new \PHPExcel_Writer_Excel2007($objPHPExcel);
$path3 = 'uploads/price_excel/' . time() . '.xls';
$result = $objWriter->save($path3); // 保存新的文件
// 将路径保存到数据库
$verModel = new VersionModel();
$result = $verModel->save(['path3' => '/'.$path3],['id' => $ver_id]);
if ($result === false){
throw new Exception($verModel->getError());
}
return $data;
}
说明:
setCellValue
设置单元格的值
$objWriter->save()
保存excel,如果带上参数,即保存新文件,否则原文件
3,Excel的导出
public function export()
{
//创建对象
$excel = new \PHPExcel();
$data = array();
foreach ($infos as $key=>$val) {
if ($infos[$key]['path3']){ // 有的话获取数据,循环遍历每个报价表的数据
$data[] = $this->readPriceExcel($infos[$key]['path3']);
$a3 = Cache::get('pro_name_'.$infos[$key]['path3']);
}
}
$a3 = Cache::get('pro_name_');
error_reporting(E_ALL);
ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);
// 进行一系列操作
// 激活当前表
$excel->setActiveSheetIndex();
ob_end_clean();//清除缓冲区,避免乱码
// 创建Excel输入对象
$write = new \PHPExcel_Writer_Excel5($excel);
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=' . (strtr('总报价表', array(' ' => '_')) . '_' . time()) . '.xls');
header("Content-Transfer-Encoding:binary");
$write->save('php://output');
}
说明:
$write->save('php://output')
将Excel输出到浏览器
4,Excel导出常见样式设置
设置水平居中
$excel->getActiveSheet()->getStyle('A2')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
设置垂直居中
$excel->getActiveSheet()->getStyle('A1:H3')->getAlignment()->setVertical(\PHPExcel_Style_Alignment::VERTICAL_CENTER);
设置单元格行高
$excel->getActiveSheet()->getDefaultRowDimension()->setRowHeight(25);
设置单元格长度
$excel->getActiveSheet()->getColumnDimension('B')->setWidth(18);
设置字体样式
$excel->getActiveSheet()->getStyle('B1')->getFont()->setName('宋体')->setSize(15)->setBold(true);
设置字体颜色
$excel->getActiveSheet()->getStyle('A3')->getFont()->getColor()->setARGB(\PHPExcel_Style_Color::COLOR_RED);
合并单元格
$excel->getActiveSheet()->mergeCells('C1:H1');
设置单元格边框
$styleThinBlackBorderOutline = array(
'borders' => array(
'allborders' => array( //设置全部边框
'style' => \PHPExcel_Style_Border::BORDER_DASHED, //粗的是thick
'color' => array ('argb' => 'FF000000'),
),
),
);
$excel->getActiveSheet()->getStyle("$a:$b")->applyFromArray($styleThinBlackBorderOutline);
设置换行
$content = '三、付款方式:'.chr(10); // chr(10)为换行
$content .= '1.定金:合同签订三天内支付合同总额的'.$arr[1].'%;'.chr(10);
$content .= '2.设备发货前支付合同总额的'.$arr[2].'%;'.chr(10);
$content .= '3.设备移交使用一个月内支付合同总额的'.$arr[3].'%;'.chr(10);
$a = 'A'.($row3+1);
$b = 'H'.($row3+5);
$excel->getActiveSheet()->setCellValue('A'.($row3+1), $content); // 设置内容
$excel->getActiveSheet()->mergeCells("$a:$b"); // 合并单元格
$excel->getActiveSheet()->getStyle($a)->getAlignment()->setWrapText(true); // 换行
5,Excel导出带图片
public function look_down()
{
$data = Db::name('user')->select();
// 导出Excel
import("Org.Util.PHPExcel");
import("Org.Util.PHPExcel.Worksheet.Drawing"); // 带图片的核心插件
import("Org.Util.PHPExcel.Writer.Excel2007");
$objPHPExcel = new \PHPExcel();
$objWriter = new \PHPExcel_Writer_Excel2007($objPHPExcel);
$objActSheet = $objPHPExcel->getActiveSheet();
// 标题
$objActSheet->setCellValue('A1', 'ID');
$objActSheet->setCellValue('B1', '昵称');
$objActSheet->setCellValue('C1', '头像');
// 内容
foreach($data as $k=>$v){
$k +=2;
$objActSheet->setCellValue('A'.$k, $v['id']);
$objActSheet->setCellValue('B'.$k, $v['nickname']);
// 图片生成
$objDrawing[$k] = new \PHPExcel_Worksheet_Drawing();
$image = './uploads/face/'.$v['head_img']; // 请勿漏掉upload之前的./
$objDrawing[$k]->setPath($image);
// 设置宽度高度
$objDrawing[$k]->setHeight(80); // 图片高度
$objDrawing[$k]->setWidth(80); // 图片宽度
/*设置图片要插入的单元格*/
$objDrawing[$k]->setCoordinates('C'.$k);
// 图片偏移距离
$objDrawing[$k]->setOffsetX(12);
$objDrawing[$k]->setOffsetY(12);
$objDrawing[$k]->setWorksheet($objPHPExcel->getActiveSheet());
// 表格高度
$objActSheet->getRowDimension($k)->setRowHeight(80);
}
$fileName = '用户表';
$date = date("Y-m-d",time());
$fileName .= "_{$date}.xls";
$fileName = iconv("utf-8", "gb2312", $fileName);
$objPHPExcel->setActiveSheetIndex(0);
header('Content-Type: application/vnd.ms-excel');
header("Content-Disposition: attachment;filename=\"$fileName\"");
header('Cache-Control: max-age=0');
$objWriter = \PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
$objWriter->save('php://output'); // 文件通过浏览器下载
}
6,注意事项
以下为本人踩过的Excel的坑,请留意
- PHPExcel为国外插件,至今没有中文文档;
- PHPExcel已废弃,没有再更新,功能上难免有一些bug,建议使用phpspreadsheet;
- 无论是PHPExcel还是phpspreadsheet,都无法读取引用的公式(INDIRECT);
