php处理excel时间数据--——使用PHPExcel判别和格式化Excel中的日期格式 .

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>';
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：

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);

//处理中文输出问题
需要将字符串转化为UTF-8编码，才能正常输出，否则中文字符将输出为空白，如下处理：
$str = iconv('gb2312', 'utf-8', $str);
或者你可以写一个函数专门处理中文字符串：
function convertUTF8($str)
if(empty($str)) return '';
return iconv('gb2312', 'utf-8', $str);
//从数据库输出数据处理方式
从数据库读取数据如：
$db = new Mysql($dbconfig);
$sql = "SELECT * FROM 表名";
$row = $db->GetAll($sql); // $row 为二维数组
$count = count($row);
for ($i = 2; $i <= $count+1; $i++) {
$objPHPExcel->getActiveSheet()->setCellValue('A' . $i, convertUTF8($row[$i-2][1]));
$objPHPExcel->getActiveSheet()->setCellValue('B' . $i, convertUTF8($row[$i-2][2]));
$objPHPExcel->getActiveSheet()->setCellValue('C' . $i, convertUTF8($row[$i-2][3]));
$objPHPExcel->getActiveSheet()->setCellValue('D' . $i, convertUTF8($row[$i-2][4]));
$objPHPExcel->getActiveSheet()->setCellValue('E' . $i, convertUTF8(date("Y-m-d", $row[$i-2][5])));
$objPHPExcel->getActiveSheet()->setCellValue('F' . $i, convertUTF8($row[$i-2][6]));
$objPHPExcel->getActiveSheet()->setCellValue('G' . $i, convertUTF8($row[$i-2][7]));
$objPHPExcel->getActiveSheet()->setCellValue('H' . $i, convertUTF8($row[$i-2][8]));
在默认sheet后，创建一个worksheet
echo date('H:i:s') . " Create new Worksheet object\n";
$objPHPExcel->createSheet();
$objWriter = PHPExcel_IOFactory::createWriter($objExcel, 'Excel5');
$objWriter-save('php://output');
顶0踩0.
