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' . 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();
