PHPExcel及Mpdf導出

PHPExcel經常使用操做

#導入類庫
require_once 'PHPExcel/Classes/PHPExcel.php';
require_once 'PHPExcel/Classes/PHPExcel/Writer/Excel5.php'; //Office 03格式寫類
require_once 'PHPExcel/Classes/PHPExcel/Writer/Excel2007.php'; //Office 07格式寫類

#基礎操做
$objPHPExcel = \PHPExcel_IOFactory::load('a.xls'); //讀入指定excel文件
$objPHPExcel->setActiveSheetIndex(0); //指定活動工做表
$objPHPExcel->getActiveSheet()->getDefaultStyle()->getFont()->setName('宋體');
$objPHPExcel->getProperties()->setTitle('xxx');

#單元格寫入
$objPHPExcel->getActiveSheet()->setCellValue('A3', 'xxx'); //設定A3單元格值爲xxx

#單元格合併
$objPHPExcel->getActiveSheet()->mergeCells('A3:B2'); //設定A1至B2單元格

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

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

#單元格繪圖
$objDrawing = new \PHPExcel_Worksheet_Drawing();
$objDrawing->setPath('a.jpg'); //指定圖片路徑。若遠程圖片需PHPExcel/Classes/PHPExcel/Worksheet/Drawing.php:106處file_exists換成file_get_contents
$objDrawing->setCoordinates('A4'); //指定在A4單元格繪圖
$objDrawing->setName('Photo');
$objDrawing->setDescription('Photo');
$objDrawing->setHeight(120);
$objDrawing->setWidth(100);
$objDrawing->setOffsetX(7);
$objDrawing->setOffsetY(7);
$objDrawing->setWorksheet($objPHPExcel->getActiveSheet());

Excel指定格式瀏覽器導出下載

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類庫
            $rendererLibraryPath = 'PHPExcel/MPDF57';
            if (!\PHPExcel_Settings::setPdfRenderer($rendererName, $rendererLibraryPath)) die('請配置pdf支持組件');
            $objWriter = new \PHPExcel_Writer_PDF($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輸出主要用於調試
            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格式導出失敗處理

• pdf中文亂碼問題

#PHPExcel/Classes/PHPExcel/Writer/PDF/mPDF.php:105處加兩行設定：
$pdf->useAdobeCJK = true;
$pdf->SetAutoFont(AUTOFONT_ALL);

• 正則調用的e模式致使導出失敗 類庫裏面多處preg_replace調用使用了元字符e，而部分低版本php不支持正則表達式e元字符
  e元字符的不當使用並致使pdf報錯的觸發點在類庫裏面大概有五六處
  因爲e元字符是一個shell下的子進程php調用，因此報錯信息不會反饋到當前php進程中，故即使你配置了錯誤打印到屏幕， 頁面也不會顯示報錯信息， 必須查看php報錯日誌
  查看php報錯日誌，把提示的preg_replace中元字符e的調用替換爲preg_replace_callback形式的調用

• 部分版本phpexcel類庫單元格樣式判斷錯誤

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

ResponseHeader設置實現Table下載

頭部設置後，直接將Table Html返回，瀏覽器自動處理爲xls下載

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>訂單號</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>1</td>
            <td>aaa</td>
        </tr>
    </tbody>
</table>
