在PHPExcel中使用isset值

Question

我目前使用isset來獲取登錄用戶的用戶名，以便將Excel文檔保存到我的站點目錄中的區域。現在我還使用第二個isset進行加密，因此用戶不能簡單地更改用戶名isset並將文件保存到其他人的目錄，除非他們知道每天或在印刷機上更改其加密密鑰。現在，當我嘗試獲取錯誤消息時，現在我不確定是否isset不適用於它或者它是用於創建文檔的文檔源文件。任何人有任何想法如何解決這個問題？

Answer 1

改變這一行

$objWriter->save('USERS/".$Username."/RiskAssessment/Risk_Assessment.xls'); 

這個

$objWriter->save("USERS/".$Username."/RiskAssessment/Risk_Assessment.xls"); 

或者這

$objWriter->save('USERS/'.$Username.'/RiskAssessment/Risk_Assessment.xls'); 

或者這

$objWriter->save("USERS/$Username/RiskAssessment/Risk_Assessment.xls"); 

注意引號。
