phpexcel常用處理

##導入類庫

require 'PHPExcel/Classes/PHPExcel.php';

require 'PHPExcel/Classes/PHPExcel/Writer/Excel5.php'; //非07格式的寫出類

##基礎屬性設定

$objPHPExcel = \PHPExcel_IOFactory::load('a.xls'); //讀入指定excel文件

$objPHPExcel->setActiveSheetIndex(0); //指定活動工作表

$objPHPExcel->getActiveSheet()->getDefaultStyle()->getFont()->setName('宋體');

$objPHPExcel->getProperties()->setTitle('xxx');

##單元格編輯

$objPHPExcel->getActiveSheet()->setCellValue('A3', 'xxx'); //設定A3單元格值為xxx

##單元格繪圖

$objDrawing = new \PHPExcel_Worksheet_Drawing();

$objDrawing->setPath('a.jpg'); //指定圖片路徑。若要遠程圖片需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文件瀏覽器下載導出

$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顯示(可用于調(diào)試)

$objWriter = new \PHPExcel_Writer_HTML($objPHPExcel);

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

利用mpdf庫從phpexcel導出pdf文件

$filename='a.pdf';

$encoded_filename = rawurlencode($filename);

$rendererName = \PHPExcel_Settings::PDF_RENDERER_MPDF; //指定通過mpdf類庫導出pdf文件

$rendererLibraryPath = 'PHPExcel/MPDF57'; //指定你下載的mpdf類庫路徑

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導出失敗的一些錯誤解決方法

##############################

##1 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);

##2 類庫里面多處preg_replace調(diào)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元字符的不當使用并導致pdf報錯的觸發(fā)點在類庫里面大概有五六處吧，

由于e元字符是一個shell下的子進程php調(diào)用，所以報錯信息不會反饋到當前php進程中，故即便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報錯日志

查看php報錯日志，把提示的preg_replace中元字符e的調(diào)用替換為preg_replace_callback形式的調(diào)用

##3 部分版本phpexcel類庫有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();
