phpexcel 使用说明

下面是总结的几个使用方法
include 'PHPExcel.php';
include 'PHPExcel/Writer/Excel2007.php';
//或者include 'PHPExcel/Writer/Excel5.php'; 用于输出.xls的

创建一个excel
$objPHPExcel = new PHPExcel();
保存excel—2007格式
$objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel);
//或者$objWriter = new PHPExcel_Writer_Excel5($objPHPExcel); 非2007格式
$objWriter->save("xxx.xlsx");
直接输出到浏览器
$objWriter = new PHPExcel_Writer_Excel5($objPHPExcel);
header("Pragma: public");
header("Expires: 0″);

加图片
$objDrawing = new PHPExcel_Worksheet_Drawing();
$objDrawing->setName('Logo');
$objDrawing->setDescription('Logo');
$objDrawing->setPath('./images/officelogo.jpg');
$objDrawing->setHeight(36);
$objDrawing->setWorksheet($objPHPExcel->getActiveSheet());
$objDrawing = new PHPExcel_Worksheet_Drawing();

$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);
$objDrawing->setWorksheet($objPHPExcel->getActiveSheet());
//处理中文输出问题

需要将字符串转化为UTF-8编码，才能正常输出，否则中文字符将输出为空白，如下处理：
 $str  = iconv('gb2312', 'utf-8', $str);
或者你可以写一个函数专门处理中文字符串：
function convertUTF8($str)
{
   if(empty($str)) return '';
   return  iconv('gb2312', 'utf-8', $str);
}
//从数据库输出数据处理方式
从数据库读取数据如：
$db = new Mysql($dbconfig);
$sql = "SELECT * FROM  表名";
$row = $db->GetAll($sql);  // $row 为二维数组
$count = count($row);
for ($i = 2; $i <= $count+1; $i++) {
 $objPHPExcel->getActiveSheet()->setCellValue('A' . $i, convertUTF8($row[$i-2][1]));
 $objPHPExcel->getActiveSheet()->setCellValue('B' . $i, convertUTF8($row[$i-2][2]));
 $objPHPExcel->getActiveSheet()->setCellValue('C' . $i, convertUTF8($row[$i-2][3]));
 $objPHPExcel->getActiveSheet()->setCellValue('D' . $i, convertUTF8($row[$i-2][4]));
 $objPHPExcel->getActiveSheet()->setCellValue('E' . $i, convertUTF8(date("Y-m-d", $row[$i-2][5])));
 $objPHPExcel->getActiveSheet()->setCellValue('F' . $i, convertUTF8($row[$i-2][6]));
 $objPHPExcel->getActiveSheet()->setCellValue('G' . $i, convertUTF8($row[$i-2][7]));
 $objPHPExcel->getActiveSheet()->setCellValue('H' . $i, convertUTF8($row[$i-2][8]));
}

在默认sheet后，创建一个worksheet
echo date('H:i:s') . " Create new Worksheet object\n";
$objPHPExcel->createSheet();
$objWriter = PHPExcel_IOFactory::createWriter($objExcel, 'Excel5');
$objWriter-save('php://output');
