快速优化网站排名的方法成功营销十大经典案例

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：PHPExcel
<?php
error_reporting(E_ALL);
set_include_path(get_include_path() . PATH_SEPARATOR . '../Classes/');

/** PHPExcel */
include 'PHPExcel.php';

/** PHPExcel_Writer_Excel2007 */
include 'PHPExcel/Writer/Excel2007.php';

// Create new PHPExcel object
echo date('H:i:s') . " Create new PHPExcel objectn";
$objPHPExcel = new PHPExcel();

// Set properties
echo 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 data
echo 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 sheet
echo 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 file
echo date('H:i:s') . " Write to Excel2007 formatn";
$objWriter = new PHPExcel_Writer_Excel2007($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
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
// 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", 0x809, 0x8, 0x0, 0x10, 0x0, 0x0);
    return;
}
function xlsEOF() {
    echo pack("ss", 0x0A, 0x00);
    return;
}
function xlsWriteNumber($Row, $Col, $Value) {
    echo pack("sssss", 0x203, 14, $Row, $Col, 0x0);
    echo pack("d", $Value);
    return;
}
function xlsWriteLabel($Row, $Col, $Value ) {
    $L = strlen($Value);
    echo pack("ssssss", 0x204, 8 + $L, $Row, $Col, 0x0, $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。
<?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可以开启com模块，就可以用它来导出Excel文件
<?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);
?>

7、可以添加图片到 EXcel

Add a drawing to a worksheet
A drawing is always represented as a separate object, which can be added to a worksheet. Therefore, you must first instantiate a new PHPExcel_Worksheet_Drawing, and assign its properties a meaningful value:
$objDrawing = new PHPExcel_Worksheet_Drawing();
$objDrawing->setName('Logo');
$objDrawing->setDescription('Logo');
$objDrawing->setPath('./images/officelogo.jpg');
$objDrawing->setHeight(36);

To add the above drawing to the worksheet, use the following snippet of code. PHPExcel creates the link between the drawing and the worksheet:
$objDrawing->setWorksheet($objPHPExcel->getActiveSheet());

You can set numerous properties on a drawing, here are some examples:
$objDrawing->setName('Paid');
$objDrawing->setDescription('Paid');
$objDrawing->setPath('./images/paid.png');
$objDrawing->setCoordinates('B15');
$objDrawing->setOffsetX(110);
$objDrawing->setRotation(25);
$objDrawing->getShadow()->setVisible(true);
$objDrawing->getShadow()->setDirection(45);
