原作者:冰山上的播客看到這篇文章的時候,很是驚訝原作者的耐心,雖然我們在平時用的也有一些,但沒有作者列出來的全,寫excel的時候,我用過pear的庫,也用過pack壓包的頭,同樣那些利用smarty等作的簡單替換xml的也用過,csv的就更不用談了。呵呵。 (COM方式不講了,這種可讀的太多了,我也寫過利用wps等進行word等的生成之類的文章)
但在讀的時候,只用過一種,具體是什麼忘了,要回去翻程式碼了。因為採用的是拿來主義,記不住。

原文內容:
最近因專案需要,需要開發一個模組,把系統中的一些資料導出成Excel,修改後再導回系統。就趁機對這個研究了一番,以下做一些總結。
基本上匯出的文件分為兩種:
1:類Excel格式,這其實不是傳統意義上的Excel文件,只是因為Excel的相容能力強,能夠正確開啟而已。修改這種檔案後再儲存,通常會提示你是否要轉換成Excel檔案。
優點:簡單。
缺點:難以產生格式,如果用來匯入需要自行分別寫對應的程式。
2:Excel格式,與類別Excel相對應,此方法產生的檔案更接近真正的Excel格式。
如果導出中文時出現亂碼,可以嘗試將字串轉換成gb2312,例如下面就把$yourStr從utf-8轉換成了gb2312:
$yourStr = mb_convert_encoding(”gb2312″, “UTF-8″, $yourStr);
以下詳細列舉幾種方法。
一、PHP匯出Excel
1:第一個推薦無比風騷的PHPExcel,官方網站:http: //www.codeplex.com/PHPExcel
導入導出都成,可以導出office2007格式,同時相容於2003。
下載下來的套件中有文件和例子,大家可以自行研究。
抄段例子出來:

$objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel);
$objWriter->save(str_replace('.php', '.xlsx', __FILE__));
// Echo done
echo date('H:i:s') . ” Done writing file.rn”;
2.使用pear的Spreadsheet_Excel_Writer類別下載位址: http://pear.php.net/package/Spreadsheet_Excel_Writer
此種依賴OLE,下載位址: http://pear.php.net/package/OLE
要注意的是導出的Excel檔案格式比較老,修改後儲存會提示是否要轉換成更新的格式。
不過可以設定格式,很強。
PHP程式碼
<?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
$workbook->close();
?>
3:利用smarty,產生符合Excel規範的XML或HTML檔案支援格式,非常完美的匯出方案。不過導出的的本質上還是XML文件,如果用來導入就需要另外處理了。
詳細內容請見rardge大俠的帖子: http ://bbs.chinaunix.net/viewthread.php?tid=745757
需要注意的是如果導出的表格行數不確定時,最好在模板中把”ss: ExpandedColumnCount=”5″ ss:ExpandedRowCount=”21″”之類的東西刪除。
4.利用pack函數印出模擬Excel格式的斷句符號,這種更接近Excel標準格式,用office2003修改後儲存,還不會彈出提示,建議用這種方法。
缺點是無格式。
PHP程式碼
<?php
// Send Header
header(”Pragma: public”);
header(”Expires: 0″);
header(”Cache-Control: must-revalidate, post-check=0, pre-check=0″);
header(”Content-Type: application/force-download”);
header(”Content-Type: application/octet-stream”);
header(”Content-Type: application/download”);;
header(”Content-Disposition: attachment;filename=test.xls “);
header(”Content-Transfer-Encoding: binary “);
// XLS Data Cell
xlsBOF();
xlsWriteLabel(1,0,”My excel line one”);
xlsWriteLabel(2,0,”My excel line two : “);
xlsWriteLabel(2,1,”Hello everybody”);
xlsEOF();
function xlsBOF() {
echo pack(”ssssss”, 0×809, 0×8, 0×0, 0×10, 0×0, 0×0);
return;
}
function xlsEOF() {
echo pack(”ss”, 0×0A, 0×00);
return;
}
function xlsWriteNumber($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;
}
?>
不過筆者在64位元linux系統中使用時失敗了,斷句符號全部變成了亂碼。
5.使用製表符、換行符的方法
製表符”t”使用者分割同一行中的列,換行符”tn”可以開啟下一行。
<?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 “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可以開啟com模組,就可以用它來匯出Excel文件
PHP程式碼
<?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);
?>
一個更好的例子: http://blog.chinaunix.net/u/16928/showart_387171.html
一、PHP導入Excel
1:還是用PHPExcel,官方網站:http: //www.codeplex.com/PHPExcel 。
2:使用PHP-ExcelReader,下載網址: http://sourceforge.net/projects/phpexcelreader
舉例:
PHP程式碼
<?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”;
}
?>
