php处理excel时间数据--——使用PHPExcel判别和格式化Excel中的日期格式 . 2015-03-10 17:55 2113人阅读 评论(0) 收藏 举报 . 最近，在做一个导入功能，在系统中使用PHPExcel类库，读取上传的Excel文件，然后进行字段映射，最后将Excel内的数据导入到系统中。其中，关于日期格式的导入，使我犯了难。 首先，如何导入日期，因为PHPExcel中日期格式在获取时得到的是数字，并不是日期字符串，于是，网上就有许多代码，用于将Excel中获取的数字转换成PHP使用的Unix Time，其实不必这么麻烦。PHPExcel中就有这样的方法：PHPExcel_Shared_Date::ExcelToPHP($value) 。可以直接使用。 如果到这里就结束，那这篇文章就有点太没意思了，在开发时，我还未一个问题犯了难，那就是如何自动判别Excel单元格是日期类型，照例，我Google了一遍，没有很好的文章解决这个问题，于是我就自己看着PHPExcel文档和源码，一边摸索，终于被我找出了方法，废话不多说，我先将代码贴上： Php代码 收藏代码 01. function Read_Excel_File2($file_name,&$result){ 02. require_once 'include/PHPExcel/Classes/PHPExcel/IOFactory.php'; 03. $result=null; 04. $objReader = PHPExcel_IOFactory::createReader('Excel5'); 05. // $objReader->setReadDataOnly(true); 06. try{ 07. $objPHPExcel = $objReader->load($file_name); 08. }catch(Exception $e){} 09. if(!isset($objPHPExcel)) return "无法解析文件"; 10. $allobjWorksheets = $objPHPExcel->getAllSheets(); 11. foreach($allobjWorksheets as $objWorksheet){ 12. $sheetname=$objWorksheet->getTitle(); 13. $highestRow = $objWorksheet->getHighestRow(); // e.g. 10 14. $highestColumn = $objWorksheet->getHighestColumn(); 15. $highestColumnIndex = PHPExcel_Cell::columnIndexFromString($highestColumn); 16. for ($row = 1; $row <= $highestRow; ++$row) { 17. for ($col = 0; $col <= $highestColumnIndex; ++$col) { 18. $cell =$objWorksheet->getCellByColumnAndRow($col, $row); 19. $value=$cell->getValue(); 20. if($cell->getDataType()==PHPExcel_Cell_DataType::TYPE_NUMERIC){ 21. $cellstyleformat=$cell->getParent()->getStyle( $cell->getCoordinate() )->getNumberFormat(); 22. $formatcode=$cellstyleformat->getFormatCode(); 23. if (preg_match('/^( $[A−Z]∗−[0−9A−F]∗ )*[hmsdy]/i', $formatcode)) { 24. $value=gmdate("Y-m-d", PHPExcel_Shared_Date::ExcelToPHP($value)); 25. }else{ 26. $value=PHPExcel_Style_NumberFormat::toFormattedString($value,$formatcode); 27. } 28. // echo $value,$formatcode,'<br>'; 29. 30. } 31. $result[$sheetname][$row-1][$col]=$value; 32. } 33. } 34. } 35. return 0; 36. } 其中，关于日期判断的部分主要是以下部分： Php代码 收藏代码 01. $cell =$objWorksheet->getCellByColumnAndRow($col, $row); 02. $value=$cell->getValue(); 03. if($cell->getDataType()==PHPExcel_Cell_DataType::TYPE_NUMERIC){ 04. $cellstyleformat=$cell->getParent()->getStyle( $cell->getCoordinate() )->getNumberFormat(); 05. $formatcode=$cellstyleformat->getFormatCode(); 06. if (preg_match('/^( $[A−Z]∗−[0−9A−F]∗ )*[hmsdy]/i', $formatcode)) { 07. $value=gmdate("Y-m-d", PHPExcel_Shared_Date::ExcelToPHP($value)); 08. }else{ 09. $value=PHPExcel_Style_NumberFormat::toFormattedString($value,$formatcode); 10. } 11. } 顺便说一下我的PHPExcel版本是 1.7.2 PhpExcel中文帮助手册|PhpExcel使用方法 复制代码 下面是总结的几个使用方法 include 'PHPExcel.php'; include 'PHPExcel/Writer/Excel2007.php'; //或者include 'PHPExcel/Writer/Excel5.php'; 用于输出.xls的 创建一个excel $objPHPExcel = new PHPExcel(); 保存excel—2007格式 $objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel); //或者$objWriter = new PHPExcel_Writer_Excel5($objPHPExcel); 非2007格式 $objWriter->save("xxx.xlsx"); 直接输出到浏览器 $objWriter = new PHPExcel_Writer_Excel5($objPHPExcel); 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="resume.xls"'); header("Content-Transfer-Encoding:binary"); $objWriter->save('php://output'); ——————————————————————————————————————– 设置excel的属性： 创建人 $objPHPExcel->getProperties()->setCreator("Maarten Balliauw"); 最后修改人 $objPHPExcel->getProperties()->setLastModifiedBy("Maarten Balliauw"); 标题 $objPHPExcel->getProperties()->setTitle("Office 2007 XLSX Test Document"); 题目 $objPHPExcel->getProperties()->setSubject("Office 2007 XLSX Test Document"); 描述 $objPHPExcel->getProperties()->setDescription("Test document for Office 2007 XLSX, generated using PHP classes."); 关键字 $objPHPExcel->getProperties()->setKeywords("office 2007 openxml php"); 种类 $objPHPExcel->getProperties()->setCategory("Test result file"); ——————————————————————————————————————– 设置当前的sheet $objPHPExcel->setActiveSheetIndex(0); 设置sheet的name $objPHPExcel->getActiveSheet()->setTitle('Simple'); 设置单元格的值 $objPHPExcel->getActiveSheet()->setCellValue('A1', 'String'); $objPHPExcel->getActiveSheet()->setCellValue('A2', 12); $objPHPExcel->getActiveSheet()->setCellValue('A3', true); $objPHPExcel->getActiveSheet()->setCellValue('C5', '=SUM(C2:C4)'); $objPHPExcel->getActiveSheet()->setCellValue('B8', '=MIN(B2:C5)'); 合并单元格 $objPHPExcel->getActiveSheet()->mergeCells('A18:E22'); 分离单元格 $objPHPExcel->getActiveSheet()->unmergeCells('A28:B28'); 保护cell $objPHPExcel->getActiveSheet()->getProtection()->setSheet(true); // Needs to be set to true in order to enable any worksheet protection! $objPHPExcel->getActiveSheet()->protectCells('A3:E13', 'PHPExcel'); 设置格式 // Set cell number formats echo date('H:i:s') .
