PHPexcel導出

寫過很多次的導出，依舊每次導出的時候都會忘記一些必要參數，趁着有時間記錄下

參數設置 $header 列頭

　　　　$datas 數據

　　　　$fileName 文件名稱

　　　　$sheet sheet名稱

　　　　$isDown 文件保存到指定文件還是直接輸出

 public function excelout($header,$datas,$fileName,$sheet,$isDown=false)
 {
 ini_set ("memory_limit","-1"); //內存無限制
 $obj = new PHPExcel();
 $obj->setActiveSheetIndex(0); //激活默認sheet
 $obj->getActiveSheet()->setTitle($sheet); //設置激活sheet的名稱
 //頭部及列設置 
 $jisuan = 0;
 foreach ($header as $key=>$headerlist ){
 if($key>25){ //當導出列大於25列時處理
 $list[]= chr(65).chr(65+$jisuan);
 $obj->getActiveSheet()->getColumnDimension(chr(65).chr(65+$jisuan))->setWidth(20);
 $obj->getActiveSheet()
 ->setCellValue($list[$key] . 1, $headerlist);
 }else{
 $list[]=chr(65+$jisuan);
 $obj->getActiveSheet()->getColumnDimension(chr(65+$jisuan))->setWidth(20);
 $obj->getActiveSheet()
 ->setCellValue($list[$key] . 1, $headerlist);
 }
 if($jisuan == 25){
 $jisuan = 0;
 }else{
 $jisuan++;
 }
 }
 //渲染數據部分
 $i = 2;
 foreach ($datas as $data){
 $j=0;
 foreach ($data as $key=>$datalist){
 $obj->getActiveSheet()
 ->setCellValue($list[$j] . $i,$datalist);
 $j++;
 }
 $i++;
 }

 header('Cache-Control: max-age=1');

 $objWriter = \PHPExcel_IOFactory::createWriter($obj, 'Excel5');
 if($isDown){ //下載文件到服務器
 $url = Core::Instance()->getAppPath();
 $file = '/temp/'.$fileName.'.xlsx';
 $_savePath = $url.$file;
 $mode = 0777;
 if (!is_dir($url)){//判斷路徑是否存在 不存在則創建
 @mkdir($url, $mode);
 @chmod($url,0777);
 if(is_file($_savePath)){//判斷文件是否存在，存在則刪除
 unlink($_savePath);
 }
 $objWriter->save($_savePath);
 return $file;
 } else{
 if(is_file($_savePath)){
 unlink($_savePath);
 }
 $objWriter->save($_savePath);//保存文件到指定路徑
 return $file;
 }

 }else{
 header("Content-Disposition:attachment;filename=$fileName.xls");
 $objWriter->save('php://output');exit; 直接輸出到瀏覽器
 }

 }
