PHPExcel及Mpdf导出

PHPExcel经常使用操做

#导入类库
require_once 'PHPExcel/Classes/PHPExcel.php';
require_once 'PHPExcel/Classes/PHPExcel/Writer/Excel5.php'; //Office 03格式写类
require_once 'PHPExcel/Classes/PHPExcel/Writer/Excel2007.php'; //Office 07格式写类

#基础操做
$objPHPExcel = \PHPExcel_IOFactory::load('a.xls'); //读入指定excel文件
$objPHPExcel->setActiveSheetIndex(0); //指定活动工做表
$objPHPExcel->getActiveSheet()->getDefaultStyle()->getFont()->setName('宋体');
$objPHPExcel->getProperties()->setTitle('xxx');

#单元格写入
$objPHPExcel->getActiveSheet()->setCellValue('A3', 'xxx'); //设定A3单元格值为xxx

#单元格合并
$objPHPExcel->getActiveSheet()->mergeCells('A3:B2'); //设定A1至B2单元格

#插入一行
$objPHPExcel->getActiveSheet()->insertNewRowBefore($pBefore = 1, $pNumRows = 1);

#单元格背景色
$objPHPExcel->getActiveSheet()->getStyle( 'A1:B10')->getFill()->getStartColor()->setARGB('FFFFFF');

#单元格绘图
$objDrawing = new \PHPExcel_Worksheet_Drawing();
$objDrawing->setPath('a.jpg'); //指定图片路径。若远程图片需PHPExcel/Classes/PHPExcel/Worksheet/Drawing.php:106处file_exists换成file_get_contents
$objDrawing->setCoordinates('A4'); //指定在A4单元格绘图
$objDrawing->setName('Photo');
$objDrawing->setDescription('Photo');
$objDrawing->setHeight(120);
$objDrawing->setWidth(100);
$objDrawing->setOffsetX(7);
$objDrawing->setOffsetY(7);
$objDrawing->setWorksheet($objPHPExcel->getActiveSheet());

Excel指定格式浏览器导出下载

function getWriter($type, $objPHPExcel)
{
    switch ($type) {
        case 'pdf':
            require_once 'PHPExcel/Classes/PHPExcel/Writer/PDF.php';
            $rendererName = \PHPExcel_Settings::PDF_RENDERER_MPDF;  //指定使用mpdf类库
            $rendererLibraryPath = 'PHPExcel/MPDF57';
            if (!\PHPExcel_Settings::setPdfRenderer($rendererName, $rendererLibraryPath)) die('请配置pdf支持组件');
            $objWriter = new \PHPExcel_Writer_PDF($objPHPExcel);
            $objWriter->setPreCalculateFormulas(false);
            break;

        case 'xls':
            require_once 'PHPExcel/Classes/PHPExcel/Writer/Excel2007.php';
            $objWriter = \PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
            break;

        case 'html':
        default:
            $objWriter = new \PHPExcel_Writer_HTML($objPHPExcel);  # html输出主要用于调试
            break;
    }

    return $objWriter;
}

function setDownStreamHeader($MIME, $file_name)
{
    ob_end_clean();
    header("Content-type: $MIME");

    $ua = $_SERVER["HTTP_USER_AGENT"];
    if (preg_match("/MSIE/", $ua) || preg_match("%Trident/7.0%", $ua) || preg_match("/Edge/", $ua)) {
        header('Content-Disposition: attachment; filename="' . rawurlencode($file_name) . '"');
    } else {
        if (preg_match("/Firefox/", $ua))
            header("Content-Disposition: attachment; filename*=\"utf8''" . $file_name . '"');
        else
            header('Content-Disposition: attachment; filename="' . $file_name . '"');
    }

    header("Pragma:no-cache");
    header("Expires:0");
}


$objPHPExcel = \PHPExcel_IOFactory::load('test.xls');
switch ($_GET['export_type']) {
	case 'xls':
		setDownStreamHeader('application/vnd.ms-excel', 'test.xls');
		$objWriter = getWriter('xls', $objPHPExcel);
		break;
	case 'pdf':
		setDownStreamHeader('application/pdf', 'test.pdf');
		$objWriter = getWriter('pdf', $objPHPExcel);
		break;
	case 'html':
	default:
		$objWriter = getWriter('html', $objPHPExcel);
		break;
}

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

PDF格式导出失败处理

• pdf中文乱码问题

#PHPExcel/Classes/PHPExcel/Writer/PDF/mPDF.php:105处加两行设定：
$pdf->useAdobeCJK = true;
$pdf->SetAutoFont(AUTOFONT_ALL);

• 正则调用的e模式致使导出失败 类库里面多处preg_replace调用使用了元字符e，而部分低版本php不支持正则表达式e元字符
  e元字符的不当使用并致使pdf报错的触发点在类库里面大概有五六处
  因为e元字符是一个shell下的子进程php调用，因此报错信息不会反馈到当前php进程中，故即使你配置了错误打印到屏幕， 页面也不会显示报错信息， 必须查看php报错日志
  查看php报错日志，把提示的preg_replace中元字符e的调用替换为preg_replace_callback形式的调用

• 部分版本phpexcel类库单元格样式判断错误

lib/PHPExcel/Classes/PHPExcel/Writer/HTML.php:1236处加个if判断
if (!$this->_useInlineCss) {
    $cssClass .= ' style' . $pSheet->getCell($endCellCoord)->getXfIndex();
}

ResponseHeader设置实现Table下载

头部设置后，直接将Table Html返回，浏览器自动处理为xls下载

header('Content-type: application/xls');
header('Content-Disposition: attachment; filename="aaa.xls"');

echo <<<EOL
<table border="1">
    <caption>表格</caption>
    <thead>
        <tr>
            <th>id</th>
            <th>订单号</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>1</td>
            <td>aaa</td>
        </tr>
    </tbody>
</table>
EOL;
