要用phpexcel从数据库中将表导出为excel格式，表中存放有图片路径现在我的代码如下：

<?php    require_once 'PHPExcel.php';    require_once 'PHPExcel/Writer/Excel5.php'; include_once 'DB_connmssql.php';$sql="select.....";$query = mssql_query($sql);$items = array();// 创建一个处理对象实例    $objExcel = new PHPExcel();       // 创建文件格式写入对象实例, uncomment    $objWriter = new PHPExcel_Writer_Excel5($objExcel);    //设置文档基本属性    $objProps = $objExcel->getProperties();    $objProps->setCreator("tt");    $objProps->setLastModifiedBy("tt");    $objProps->setTitle("tt");    $objProps->setSubject("tt ");    $objProps->setDescription("tt ");    $objProps->setKeywords("tt ");    $objProps->setCategory("变动报表");       //*************************************    //设置当前的sheet索引，用于后续的内容操作。    //一般只有在使用多个sheet的时候才需要显示调用。    //缺省情况下，PHPExcel会自动创建第一个sheet被设置SheetIndex=0    $objExcel->setActiveSheetIndex(0);    $objActSheet = $objExcel->getActiveSheet();       //设置当前活动sheet的名称    $objActSheet->setTitle('tttt');       //*************************************    //    //设置宽度，这个值和EXCEL里的不同，不知道是什么单位，略小于EXCEL中的宽度$objActSheet->getColumnDimension('A')->setWidth(20); $objActSheet->getColumnDimension('B')->setWidth(15); $objActSheet->getRowDimension(1)->setRowHeight(30); $objActSheet->getRowDimension(2)->setRowHeight(27); $objActSheet->getRowDimension(3)->setRowHeight(16);  //设置单元格的值  $objActSheet->setCellValue('A1', 'Titile'); //合并单元格$objActSheet->mergeCells('A1:N1'); //设置样式$objStyleA1 = $objActSheet->getStyle('A1');    $objStyleA1->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);$objFontA1 = $objStyleA1->getFont();    $objFontA1->setName('宋体');    $objFontA1->setSize(18);  $objFontA1->setBold(true);    //设置居中对齐$objActSheet->getStyle('A2')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);$objActSheet->getStyle('B2')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);$objActSheet->setCellValue('A2', 'Shoes Picture'); $objActSheet->setCellValue('B2', 'Product code'); //设置边框$objActSheet->getStyle('A2')->getBorders()->getTop()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN );	$objActSheet->getStyle('A2')->getBorders()->getLeft()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN );	$objActSheet->getStyle('A2')->getBorders()->getRight()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN );	$objActSheet->getStyle('A2')->getBorders()->getBottom()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN );	$objActSheet->getStyle('B2')->getBorders()->getTop()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN );	$objActSheet->getStyle('B2')->getBorders()->getLeft()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN );	$objActSheet->getStyle('B2')->getBorders()->getRight()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN );	$objActSheet->getStyle('B2')->getBorders()->getBottom()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN );	$i=1;$query = mssql_query($sql);$query1 = mssql_query($sql);$items=array();$sales_sum=$sales_sum+$row1["total_sales"];while($row=mssql_fetch_array($query)){	$row["Photo"]="../picture/".$row["Photo"];	$n=$i+2;	$objActSheet->getStyle('B'.$n)->getNumberFormat()->setFormatCode('@');	$objActSheet->getStyle('E'.$n)->getNumberFormat()->setFormatCode('@');	$objActSheet->getRowDimension($n)->setRowHeight(16);	$objActSheet->getStyle('A'.$n)->getBorders()->getTop()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN );	$objActSheet->getStyle('A'.$n)->getBorders()->getLeft()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN );	$objActSheet->getStyle('A'.$n)->getBorders()->getRight()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN );	$objActSheet->getStyle('A'.$n)->getBorders()->getBottom()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN );	$objActSheet->getStyle('B'.$n)->getBorders()->getTop()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN );	$objActSheet->getStyle('B'.$n)->getBorders()->getLeft()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN );	$objActSheet->getStyle('B'.$n)->getBorders()->getRight()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN );	$objActSheet->getStyle('B'.$n)->getBorders()->getBottom()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN );	$objActSheet->setCellValue('A'.$n, $row["Photo"]);	$objActSheet->setCellValue('B'.$n, $row["Article_No"]);		$i++;} $outputFileName = "tables addminus1.xls";    header("Content-Type: application/force-download");header("Content-Type: application/octet-stream");header("Content-Type: application/download");header('Content-Disposition:inline;filename="'.$outputFileName.'"');header("Content-Transfer-Encoding: binary");header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");header("Cache-Control: must-revalidate, post-check=0, pre-check=0");header("Pragma: no-cache");$objWriter->save('php://output');  ?>

导出的excel如下

请教下要把图片的路径换成真实的图片输出代码该怎么修改？还有怎么让excel的标题分成两行显示并加粗，代码该如何修改？

回复讨论(解决方案)

图片如下

标题换行只需在需要换行的地方加上换行符
比如 "Product \ncode"

其他的明天说

$objActSheet->setCellValue('A2', 'Shoes Picture'); $objActSheet->setCellValue('B2', 'Product code'); $objActSheet->setCellValue('C2', 'Original Retail  Price (VAT)'); $objActSheet->setCellValue('D2', '  Total \nOrdered Qty'); $objActSheet->setCellValue('E2', '  Total 		Sales Qty'); $objActSheet->setCellValue('F2', 'Sellthru'); $objActSheet->setCellValue('G2', 'Total Sales'); $objActSheet->setCellValue('H2', 'Cumulated Qty'); $objActSheet->setCellValue('I2', 'Cumulated  /nQty %');

/n \n都试过了...都不行。

加粗范例
$objPHPExcel->getActiveSheet()->getStyle('B1')->getFont()->setBold(true);

添加图片  范例
$objDrawing = new PHPExcel_Worksheet_Drawing();
$objDrawing->setName('Logo');
$objDrawing->setDescription('Logo');
$objDrawing->setPath('./images/officelogo.jpg');
$objDrawing->setHeight(36);
$objDrawing->setCoordinates('B15');
$objDrawing->setOffsetX(110);
$objDrawing->setRotation(25);
$objDrawing->getShadow()->setVisible(true);
$objDrawing->getShadow()->setDirection(45);
$objDrawing->setWorksheet($objPHPExcel->getActiveSheet());

$objDrawing = new PHPExcel_Worksheet_Drawing();while($row=mssql_fetch_array($query)){	if(''!==$row["Photo"]){	$row["Photo"]="../picture/".$row["Photo"];	$objDrawing->setName('Logo');	$objDrawing->setDescription('Logo');	$objDrawing->setPath($row["Photo"]);	$objDrawing->setHeight(36);	$objDrawing->setCoordinates('B15');	$objDrawing->setOffsetX(110);	$objDrawing->setRotation(25);	$objDrawing->getShadow()->setVisible(true);	$objDrawing->getShadow()->setDirection(45);	$objDrawing->setWorksheet($objExcel->getActiveSheet());	}

$objDrawing = new PHPExcel_Worksheet_Drawing();
要放在循环内，即每个图片需要一个 PHPExcel_Worksheet_Drawing 实例

setHeight 图片高
setCoordinates 所在单元格
setOffsetX 左上角相对单元格的x偏移
setRotation 旋转角
更多的方法请见文档

我 setCoordinates('B15') （15行B列）
你也在 setCoordinates('B15') 吗？

我 setCoordinates('B15') （15行B列）
你也在 setCoordinates('B15') 吗？
果然这样，但又有个问题，我把图片设置到了图片名称出现的位置。

while($row=mssql_fetch_array($query)){	$objDrawing = new PHPExcel_Worksheet_Drawing();	if(''!==$row["Photo"]){	$row["Photo"]="picture/".$row["Photo"];	$objDrawing->setName('Logo');	$objDrawing->setDescription('Logo');	$objDrawing->setPath($row["Photo"]);	$objDrawing->setHeight(36);	$objDrawing->setCoordinates('A'.$aa);//图片名称所在的单元格	$objDrawing->setOffsetX(80);	$objDrawing->setRotation(25);	$objDrawing->getShadow()->setVisible(true);	$objDrawing->getShadow()->setDirection(45);	$objDrawing->setWorksheet($objExcel->getActiveSheet());	$aa++;	}

出来效果是这样的

图片只是出现在单元格的位置，并不是单元格的值
要达到下面的效果该怎么设置单元格？

不是说了吗？
$objDrawing->setOffsetX(80); //表示图片左边距是 80
$objDrawing->setRotation(25); //表示旋转 25 度
显然都不是你需要的
你只需设置单元格居中排列

批量设置，我一般用 PHPExcel_Style 来写，如

	$style_obj = new PHPExcel_Style(); 	$style_array = array( 		'borders' => array( 			'top' => array('style' => PHPExcel_Style_Border::BORDER_THIN),			'left' => array('style' => PHPExcel_Style_Border::BORDER_THIN),			'bottom' => array('style' => PHPExcel_Style_Border::BORDER_THIN),			//'right' => array('style' => PHPExcel_Style_Border::BORDER_THIN) 			),		'alignment' => array(			'horizontal' => PHPExcel_Style_Alignment::HORIZONTAL_CENTER,			'vertical'	=> PHPExcel_Style_Alignment::VERTICAL_CENTER,			'wrap'	=> true			)		);	$style_obj->applyFromArray($style_array); 	$sheet->setSharedStyle($style_obj, "B$y:$x$y");

当然一个个的设置也是没有问题的

	$style_obj = new PHPExcel_Style(); 	$style_array = array( 		'borders' => array( 			'top' => array('style' => PHPExcel_Style_Border::BORDER_THIN),			'left' => array('style' => PHPExcel_Style_Border::BORDER_THIN),			'bottom' => array('style' => PHPExcel_Style_Border::BORDER_THIN),			//'right' => array('style' => PHPExcel_Style_Border::BORDER_THIN) 			),		'alignment' => array(			'horizontal' => PHPExcel_Style_Alignment::HORIZONTAL_CENTER,			'vertical'	=> PHPExcel_Style_Alignment::VERTICAL_CENTER,			'wrap'	=> true			)		);	$style_obj->applyFromArray($style_array); 	$sheet->setSharedStyle($style_obj, "B$y:$x$y");

当然一个个的设置也是没有问题的
格式搞定了现在就剩两个问题了：
1、导出图片到cell里面。
2、页面上有导出excel按钮，怎么通过点击按钮，将页面的参数传到后台（前台页面不跳转）以导出对应的excel。
大师把这个分数一起拿走吧小弟分数不多... http://bbs.csdn.net/topics/390730241

1、导出图片上面已经说了，你也做到了。只是要注意调整格式
2、导出excel按钮可以是表单的提交按钮，设置表单的 target 指向一个隐藏的 iframe 就不会跳转了

<form method=post action=excel.php target=down><input type=submit value='导出excel'></form><iframe name=down style='display:none'></iframe>

<form method=post action=excel.php target=down><input type=submit value='导出excel'></form><iframe name=down style='display:none'></iframe>

大师再请教个问题，向excel中写入图片时，当图片不存在，phpexcel会抛出异常不能形成excel文件，于是我捕获异常（被注释掉的代码）

if(''!==$row["Photo"]){	//	$row["Photo"]="picture/".$row["Photo"];	//try{		$objDrawing->setName('Logo');		$objDrawing->setDescription('Logo');		$objDrawing->setPath($row["Photo"]);		$objDrawing->setHeight(36);		$objDrawing->setCoordinates('A'.$n);//图片名称所在的单元格		$objDrawing->setOffsetX(15);		$objDrawing->setRotation(25);		$objDrawing->getShadow()->setVisible(true);		$objDrawing->getShadow()->setDirection(45);		$objDrawing->setWorksheet($objExcel->getActiveSheet());// 	}catch (Exception $e){// 		$objDrawing->setName('Logo1');// 		$objDrawing->setDescription('Logo1');// 		$objDrawing->setPath("notf.jpg");// 		$objDrawing->setHeight(36);// 		$objDrawing->setCoordinates('A'.$n);//图片名称所在的单元格// 		$objDrawing->setOffsetX(15);// 		$objDrawing->setRotation(25);// 		$objDrawing->getShadow()->setVisible(true);// 		$objDrawing->getShadow()->setDirection(45);// 		$objDrawing->setWorksheet($objExcel->getActiveSheet());// 	}	}

这样就算图片不存在也能导出excel，但导出的excel就是打不开，请问如何解决？

if(file_exists("picture/".$row["Photo"])) {   .....  $objDrawing->setWorksheet($objExcel->getActiveSheet());}

if(file_exists("picture/".$row["Photo"])) {   .....  $objDrawing->setWorksheet($objExcel->getActiveSheet());}

请问大师输出pdf文档该怎么输出呢？
我这样输出文件很小很小，而且打不开

/输出内容    // if($outtype=="pdf"){// header('Content-Type: application/pdf');// header('Content-Disposition: attachment;filename="Global Network.pdf"');// header('Cache-Control: max-age=0');// $objWriter = PHPExcel_IOFactory::createWriter($objExcel, 'PDF');// $objWriter->save('php://output');// exit;//}ELSE{$outputFileName = "Global Network.xls";    //到文件    //$objWriter->save($outputFileName);    //到浏览器header("Content-Type: application/force-download");header("Content-Type: application/octet-stream");header("Content-Type: application/download");header('Content-Disposition:inline;filename="'.$outputFileName.'"');header("Content-Transfer-Encoding: binary");header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");// header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");header("Cache-Control: must-revalidate, post-check=0, pre-check=0");header("Pragma: no-cache");$objWriter->save('php://output');  //exit;//}

我没做过，刚才试了一下
不但样式难看，而且不能显示中文
