PHP导入导出Excel方法

原作者：冰山上的播客看到这篇文章的时候，很是惊讶原作者的耐心，虽然我们在平时用的也有一些，但没有作者列出来的全，写excel的时候，我用过pear的库，也用过pack压包的头，同样那些利用smarty等作的简单替换xml的也用过，csv的就更不用谈了。呵呵。（COM方式不讲了，这种可读的太多了，我也写过利用wps等进行word等的生成之类的文章 ）但是在读的时候，只用过一种，具体是什么忘了，要回去翻代码了。因为采用的是拿来主义，记不住。原文地址：http://xinsync.xju.edu.cn/index.php/archives/3858原文内容：

最近因项目需要，需要开发一个模块，把系统中的一些数据导出成Excel，修改后再导回系统。就趁机对这个研究了一番，下面进行一些总结。基本上导出的文件分为两种：1：类Excel格式，这个其实不是传统意义上的Excel文件，只是因为Excel的兼容能力强，能够正确打开而已。修改这种文件后再保存，通常会提示你是否要转换成Excel文件。优点：简单。缺点：难以生成格式，如果用来导入需要自己分别编写相应的程序。2：Excel格式，与类Excel相对应，这种方法生成的文件更接近于真正的Excel格式。

如果导出中文时出现乱码，可以尝试将字符串转换成gb2312，例如下面就把$yourStr从utf-8转换成了gb2312:$yourStr = mb_convert_encoding(”gb2312″, “UTF-8″, $yourStr);

下面详细列举几种方法。一、PHP导出Excel

1：第一推荐无比风骚的PHPExcel，官方网站： http://www.codeplex.com/PHPExcel导入导出都成，可以导出office2007格式，同时兼容2003。下载下来的包中有文档和例子，大家可以自行研究。抄段例子出来：

PATH_SEPARATOR . ‘../Classes/’); /** PHPExcel */include ‘PHPExcel.php’; /** PHPExcel_Writer_Excel2007 */include ‘PHPExcel/Writer/Excel2007.php’; // Create new PHPExcel objectecho date(’H:i:s’) . ” Create new PHPExcel objectn”;$objPHPExcel = new PHPExcel(); // Set propertiesecho date(’H:i:s’) . ” Set propertiesn”;$objPHPExcel->getProperties()->setCreator(”Maarten Balliauw”);$objPHPExcel->getProperties()->setLastModifiedBy(”Maarten Balliauw”);$objPHPExcel->getProperties()->setTitle(”Office 2007 XLSX Test Document”);$objPHPExcel->getProperties()->setSubject(”Office 2007 XLSX Test Document”);$objPHPExcel->getProperties()->setDescrīption(”Test document for Office 2007 XLSX, generated using PHP classes.”);$objPHPExcel->getProperties()->setKeywords(”office 2007 openxml php”);$objPHPExcel->getProperties()->setCategory(”Test result file”); // Add some dataecho date(’H:i:s’) . ” Add some datan”;$objPHPExcel->setActiveSheetIndex(0);$objPHPExcel->getActiveSheet()->setCellValue(’A1′, ‘Hello’);$objPHPExcel->getActiveSheet()->setCellValue(’B2′, ‘world!’);$objPHPExcel->getActiveSheet()->setCellValue(’C1′, ‘Hello’);$objPHPExcel->getActiveSheet()->setCellValue(’D2′, ‘world!’); // Rename sheetecho date(’H:i:s’) . ” Rename sheetn”;$objPHPExcel->getActiveSheet()->setTitle(’Simple’); // Set active sheet index to the first sheet, so Excel opens this as the first sheet$objPHPExcel->setActiveSheetIndex(0); // Save Excel 2007 fileecho date(’H:i:s’) . ” Write to Excel2007 formatn”;$objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel);$objWriter->save(str_replace(’.php’, ‘.xlsx’, __FILE__)); // Echo doneecho date(’H:i:s’) . ” Done writing file.rn”;

2、使用pear的Spreadsheet_Excel_Writer类下载地址： http://pear.php.net/package/Spreadsheet_Excel_Writer此类依赖于OLE,下载地址：http://pear.php.net/package/OLE需要注意的是导出的Excel文件格式比较老，修改后保存会提示是否转换成更新的格式。不过可以设定格式，很强大。

PHP代码<?phprequire_once ‘Spreadsheet/Excel/Writer.php’; // Creating a workbook$workbook = new Spreadsheet_Excel_Writer(); // sending HTTP headers$workbook->send(’test.xls’); // Creating a worksheet$worksheet =& $workbook->addWorksheet(’My first worksheet’); // The actual data$worksheet->write(0, 0, ‘Name’);$worksheet->write(0, 1, ‘Age’);$worksheet->write(1, 0, ‘John Smith’);$worksheet->write(1, 1, 30);$worksheet->write(2, 0, ‘Johann Schmidt’);$worksheet->write(2, 1, 31);$worksheet->write(3, 0, ‘Juan Herrera’);$worksheet->write(3, 1, 32); // Let’s send the file$workbook->close();?>

3:利用smarty，生成符合Excel规范的XML或HTML文件支持格式，非常完美的导出方案。不过导出来的的本质上还是XML文件，如果用来导入就需要另外处理了。详细内容请见rardge大侠的帖子：http://bbs.chinaunix.net/viewthread.php?tid=745757

需要注意的是如果导出的表格行数不确定时，最好在模板中把”ss:ExpandedColumnCount=”5″ ss:ExpandedRowCount=”21″”之类的东西删掉。

4、利用pack函数打印出模拟Excel格式的断句符号，这种更接近于Excel标准格式，用office2003修改后保存，还不会弹出提示，推荐用这种方法。缺点是无格式。

PHP代码<?php// Send Headerheader(”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/octet-stream”);header(”Content-Type: application/download”);;header(”Content-Disposition: attachment;filename=test.xls “);header(”Content-Transfer-Encoding: binary “);// XLS Data Cell xlsBOF();xlsWriteLabel(1,0,”My excel line one”);xlsWriteLabel(2,0,”My excel line two : “);xlsWriteLabel(2,1,”Hello everybody”); xlsEOF(); function xlsBOF() {echo pack(”ssssss”, 0×809, 0×8, 0×0, 0×10, 0×0, 0×0);return;}function xlsEOF() {echo pack(”ss”, 0×0A, 0×00);return;}function xlsWriteNumber($Row, $Col, $Value) {echo pack(”sssss”, 0×203, 14, $Row, $Col, 0×0);echo pack(”d”, $Value);return;}function xlsWriteLabel($Row, $Col, $Value ) {$L = strlen($Value);echo pack(”ssssss”, 0×204, 8 + $L, $Row, $Col, 0×0, $L);echo $Value;return;}?>不过笔者在64位linux系统中使用时失败了，断句符号全部变成了乱码。 5、使用制表符、换行符的方法制表符”t”用户分割同一行中的列，换行符”tn”可以开启下一行。<?phpheader(”Content-Type: application/vnd.ms-execl”);header(”Content-Disposition: attachment; filename=myExcel.xls”);header(”Pragma: no-cache”);header(”Expires: 0″);/*first line*/echo “hello”.”t”;echo “world”.”t”;echo “tn”; /*start of second line*/echo “this is second line”.”t”;echo “Hi,pretty girl”.”t”;echo “tn”;?>

6、使用com如果你的PHP可以开启com模块，就可以用它来导出Excel文件

PHP代码<?PHP$filename = “c:/spreadhseet/test.xls”;$sheet1 = 1;$sheet2 = “sheet2″;$excel_app = new COM(”Excel.application”) or Die (”Did not connect”);print “Application name: {$excel_app->Application->value}n” ;print “Loaded version: {$excel_app->Application->version}n”;$Workbook = $excel_app->Workbooks->Open(”$filename”) or Die(”Did not open $filename $Workbook”);$Worksheet = $Workbook->Worksheets($sheet1);$Worksheet->activate;$excel_cell = $Worksheet->Range(”C4″);$excel_cell->activate;$excel_result = $excel_cell->value;print “$excel_resultn”;$Worksheet = $Workbook->Worksheets($sheet2);$Worksheet->activate;$excel_cell = $Worksheet->Range(”C4″);$excel_cell->activate;$excel_result = $excel_cell->value;print “$excel_resultn”;#To close all instances of excel:$Workbook->Close;unset($Worksheet);unset($Workbook);$excel_app->Workbooks->Close();$excel_app->Quit();unset($excel_app);?>

一、PHP导入Excel

1：还是用PHPExcel，官方网站： http://www.codeplex.com/PHPExcel。

2：使用PHP-ExcelReader,下载地址: http://sourceforge.net/projects/phpexcelreader举例：

PHP代码<?phprequire_once ‘Excel/reader.php’; // ExcelFile($filename, $encoding);$data = new Spreadsheet_Excel_Reader(); // Set output Encoding.$data->setOutputEncoding(’utf8′); $data->read(’ jxlrwtest.xls’); error_reporting(E_ALL ^ E_NOTICE); for ($i = 1; $i <= $data->sheets[0]['numRows']; $i++) {for ($j = 1; $j <= $data->sheets[0]['numCols']; $j++) {echo “”'.$data->sheets[0]['cells'][$i][$j].””,”;}echo “n”;} ?>
