如何把系統中的一些數據導出成Excel,修改後再導回系統,下面進行一些總結。
基本上導出的文件分為兩種:
1:類Excel格式,這個其實不是傳統意義上的Excel文件,只是因為Excel的兼容能力強,能夠正確打開而已。修改這種文件後再保存,通常會提示你是否要轉換成Excel文件。
優點:簡單。
缺點:難以生成格式,如果用來導入需要自己分別編寫相應的程序。
2:Excel格式,與類Excel相對應,這種方法生成的文件更接近於真正的Excel格式。
如果導出中文時出現亂碼,可以嘗試將字符串轉換成gb2312,例如下面就把$yourStr從utf-8轉換成了gb2312:
$yourStr = mb_convert_encoding;
下面詳細列舉幾種方法。
一、PHP導出Excel
1:第一推薦無比風騷的PHPExcel,官方網站:
導入導出都成,可以導出Office2007格式,同時兼容2003。
下載下來的包中有文檔和例子,大家可以自行研究。
抄段例子出來:
PHP代碼

$objPHPExcel-getActiveSheet-setCellValue;
$objPHPExcel-getActiveSheet-setCellValue;
$objPHPExcel-getActiveSheet-setCellValue;
// Rename sheet
echo date . ” Rename sheet“n”;
$objPHPExcel-getActiveSheet-setTitle;
// Set active sheet index to the first sheet, so Excel opens this as the first sheet
$objPHPExcel-setActiveSheetIndex;
// Save Excel 2007 file
echo date . ” Write to Excel2007 format“n”;
$objWriter = new PHPExcel_Writer_Excel2007;
$objWriter-save);
// Echo done
echo date . ” Done writing file.“r“n”;
2、使用pear的Spreadsheet_Excel_Writer類
此類依賴於OLE,
需要注意的是導出的Excel文件格式比較老,修改後保存會提示是否轉換成更新的格式。
不過可以設定格式,很強大。
PHP代碼
?PHP
require_once ‘Spreadsheet/Excel/Writer.PHP’;
// Creating a workbook
$workbook = new Spreadsheet_Excel_Writer;
// sending HTTP headers
$workbook-send;
// Creating a worksheet
$worksheet =& $workbook-addWorksheet;
// The actual data
$worksheet-write;
$worksheet-write;
$worksheet-write;
$worksheet-write;
$worksheet-write;
$worksheet-write;
$worksheet-write;
$worksheet-write;
// Let’s send the file
$workbook-close;
3:利用smarty,生成符合Excel規范的XML或Html文件
支持格式,非常完美的導出方案。不過導出來的的本質上還是XML文件,如果用來導入就需要另外處理了。
詳細內容請見rardge大俠的文章:
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″”之類的東西刪掉。
4、利用pack函數打印出模擬Excel格式的斷句符號,這種更接近於Excel標准格式,用Office2003修改後保存,還不會彈出提示,推薦用這種方法。
缺點是無格式。
PHP代碼
?PHP
// Send Header
header;
header;
header;
header;
header;
header;;
header;
header;
// XLS Data Cell
xlsBOF;
xlsWriteLabel;
xlsWriteLabel;
xlsWriteLabel;
xlSEOF;
function xlsBOF
function xlSEOF
function xlsWriteNumber
function xlsWriteLabel
不過在64位Linux系統中使用時失敗了,斷句符號全部變成了亂碼。
5、使用制表符、換行符的方法
制表符”“t”用戶分割同一行中的列,換行符”“t“n”可以開啟下一行。
?PHP
header;
header;
header;
header;
/*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可以開啟com模塊,就可以用它來導出Excel文件
PHP代碼
<?
$filename = “c:/spreadhseet/test.xls”;
$sheet1 = 1;
$sheet2 = “sheet2″;
$Excel_app = new COM or DIE ;
print “Application name: “n” ;
print “Loaded version: “n”;
$Workbook = $Excel_app-Workbooks-Open or DIE;
$Worksheet = $Workbook-Worksheets;
$Worksheet-activate;
$Excel_cell = $Worksheet-Range;
$Excel_cell-activate;
$excel_result = $Excel_cell-value;
print “$Excel_result“n”;
$Worksheet = $Workbook-Worksheets;
$Worksheet-activate;
$Excel_cell = $Worksheet-Range;
$Excel_cell-activate;
$excel_result = $Excel_cell-value;
print “$Excel_result“n”;
#To close all instances of Excel:
$Workbook-Close;
unset;
unset;
$Excel_app-Workbooks-Close;
$Excel_app-Quit;
unset;
?>
一個更好的例子:
一、PHP導入Excel
1:還是用PHPExcel,官方網站: 。
2:使用PHP-ExcelReader,下載地址:
舉例:
PHP代碼
<?PHP
require_once ‘Excel/reader.PHP’;
// ExcelFile;
$data = new Spreadsheet_Excel_Reader;
// Set output Encoding.
$data-setOutputEncoding;
$data-read;
error_reporting;
for
echo ““n”;
?>
