php导入导出excel
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:
PHP代码

$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”;
}
?>
