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″);

 header("Cache-Control:must-revalidate, post-check=0, pre-check=0″);

 header("Content-Type:application/force-download");

 header("Content-Type:application/vnd.ms-execl");

 header("Content-Type:application/octet-stream");

 header("Content-Type:application/download");;

 header('Content-Disposition:attachment;filename="resume.xls"');

 header("Content-Transfer-Encoding:binary");

 $objWriter->save('php://output');

 $objPHPExcel->getActiveSheet()->getStyle('D12')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_RIGHT);

 $objPHPExcel->getActiveSheet()->getStyle('D13')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_RIGHT);

 $objPHPExcel->getActiveSheet()->getStyle('A18')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_JUSTIFY);

 //垂直居中

 $objPHPExcel->getActiveSheet()->getStyle('A18')->getAlignment()->setVertical(PHPExcel_Style_Alignment::VERTICAL_CENTER);

 设置column的border

 $objPHPExcel->getActiveSheet()->getStyle('A4')->getBorders()->getTop()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);

 $objPHPExcel->getActiveSheet()->getStyle('B4')->getBorders()->getTop()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);

 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->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);

 $objDrawing->setWorksheet($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');
