PHPExcel笔记, mpdf导出_PHP

phpexcel常用处理

##导入类库require 'PHPExcel/Classes/PHPExcel.php';require 'PHPExcel/Classes/PHPExcel/Writer/Excel5.php'; //非07格式的写出类 ##基础属性设定$objPHPExcel = \PHPExcel_IOFactory::load('a.xls'); //读入指定excel文件$objPHPExcel->setActiveSheetIndex(0); //指定活动工作表$objPHPExcel->getActiveSheet()->getDefaultStyle()->getFont()->setName('宋体');$objPHPExcel->getProperties()->setTitle('xxx'); ##单元格编辑$objPHPExcel->getActiveSheet()->setCellValue('A3', 'xxx'); //设定A3单元格值为xxx ##单元格绘图$objDrawing = new \PHPExcel_Worksheet_Drawing();$objDrawing->setPath('a.jpg'); //指定图片路径。若要远程图片需PHPExcel/Classes/PHPExcel/Worksheet/Drawing.php:106处file_exists换成file_get_contents$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文件浏览器下载导出$filename='a.xls';$encoded_filename = rawurlencode($filename);$ua = $_SERVER["HTTP_USER_AGENT"];header('Content-type: application/vnd.ms-excel');if (preg_match("/MSIE/", $ua) || preg_match("/Trident\/7.0/", $ua) || preg_match("/Edge/", $ua)) {  header('Content-Disposition: attachment; filename="' . $encoded_filename . '"');} else if (preg_match("/Firefox/", $ua)) {  header("Content-Disposition: attachment; filename*=\"utf8''" . $filename . '"');} else {  header('Content-Disposition: attachment; filename="' . $filename . '"');}header("Pragma:no-cache");header("Expires:0");$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');$objWriter->save('php://output'); ##excel文件html显示(可用于调试)$objWriter = new \PHPExcel_Writer_HTML($objPHPExcel);$objWriter->save('php://output');

利用mpdf库从phpexcel导出pdf文件

$filename='a.pdf';$encoded_filename = rawurlencode($filename);$rendererName = \PHPExcel_Settings::PDF_RENDERER_MPDF; //指定通过mpdf类库导出pdf文件$rendererLibraryPath = 'PHPExcel/MPDF57'; //指定你下载的mpdf类库路径if (!\PHPExcel_Settings::setPdfRenderer(  $rendererName,  $rendererLibraryPath)) {  die(    'Please set the $rendererName and $rendererLibraryPath values' .   <i style="color:transparent">@本文来源gaodai$ma#com搞$代*码6网</i><b>搞代gaodaima码</b> PHP_EOL .    ' as appropriate for your directory structure'  );}header('Content-type: application/pdf');if (preg_match("/MSIE/", $ua) || preg_match("/Trident\/7.0/", $ua) || preg_match("/Edge/", $ua)) {  header('Content-Disposition: attachment; filename="' . $encoded_filename . '"');} else if (preg_match("/Firefox/", $ua)) {  header("Content-Disposition: attachment; filename*=\"utf8''" . $file_name . '"');} else {  header('Content-Disposition: attachment; filename="' . $file_name . '"');}header("Pragma:no-cache");header("Expires:0");$objWriter = new \PHPExcel_Writer_PDF($objPHPExcel);$objWriter->setPreCalculateFormulas(false);$objWriter->save('php://output');  ################################pdf导出失败的一些错误解决方法############################## ##1 pdf中文乱码问题PHPExcel/Classes/PHPExcel/Writer/PDF/mPDF.php:105处加两行设定：$pdf->useAdobeCJK = true;$pdf->SetAutoFont(AUTOFONT_ALL); ##2 类库里面多处preg_replace调用使用了元字符e，而部分低版本php不支持正则表达式e元字符e元字符的不当使用并导致pdf报错的触发点在类库里面大概有五六处吧，由于e元字符是一个shell下的子进程php调用，所以报错信息不会反馈到当前php进程中，故即便你配置了错误打印到屏幕， 页面也不会显示报错信息， 必须查看php报错日志查看php报错日志，把提示的preg_replace中元字符e的调用替换为preg_replace_callback形式的调用 ##3 部分版本phpexcel类库有单元格样式判断错误lib/PHPExcel/Classes/PHPExcel/Writer/HTML.php:1236处加个if判断if (!$this->_useInlineCss) {  $cssClass .= ' style' . $pSheet->getCell($endCellCoord)->getXfIndex();
