PHP导入导出Excel方法

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：

$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”);

$objPHPExcel->setActiveSheetIndex(0);

$objPHPExcel->getActiveSheet()->setCellValue(’A1′, ‘Hello’);

$objPHPExcel->getActiveSheet()->setCellValue(’B2′, ‘world!’);

$objPHPExcel->getActiveSheet()->setCellValue(’C1′, ‘Hello’);

$objPHPExcel->getActiveSheet()->setCellValue(’D2′, ‘world!’);

// Rename sheet

echo date(’H:i:s’) . ” Rename sheet\n”;

$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 file

echo date(’H:i:s’) . ” Write to Excel2007 format\n”;

$objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel);

$objWriter->save(str_replace(’.php’, ‘.xlsx’, __FILE__));

// Echo done

echo date(’H:i:s’) . ” Done writing file.\r\n”;

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

<?php

require_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 Header

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/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”\t\n”可以开启下一行。

<?php

header(”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 “\t\n”;

/*start of second line*/

echo “this is second line”.”\t”;

echo “Hi,pretty girl”.”\t”;

echo “\t\n”;

?>

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_result\n”;

$Worksheet = $Workbook->Worksheets($sheet2);

$Worksheet->activate;

$excel_cell = $Worksheet->Range(”C4″);

$excel_cell->activate;

$excel_result = $excel_cell->value;

print “$excel_result\n”;

#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

<?php

require_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”;

}

?>
