我一直在使用堆棧溢出好幾年，但現在只有一個帳戶，因爲我從來沒有變得如此卡住，我需要問一個問題（不是因爲我很聰明，因爲我的代碼很簡單！），無論如何，我的問題;PHP Excel導出無法識別辦公室2007
我正在通過PHP導出一個.xls格式的表格，其中包含來自我的MYSQL表格中幾個表格的信息。所有的信息和造型完美地工作。唯一的問題是，當它在Office 2007中打開時，我收到以下錯誤消息：
「您試圖打開的文件'export.xls'是與文件擴展名指定的格式不同的文件。文件在打開文件之前沒有損壞並且來自可信來源，您確定要查看此文件嗎？「
所以總結一下，所有的信息都從數據庫中取得成功並且所有的樣式工作 - 我知道這是真實的，因爲當我在彈出的對話框中單擊'是'時，我看到所有的東西都完美地佈置。
下面是Excel的出口類：

有沒有辦法改變它？或者我必須找到一個不同的類來創建PHP的Excel文件？ – Thejoker123 2013-03-03 12:21:22
您可以爲SpreadsheetML（.xml）提供正確的擴展名，或者您可以找到可以編寫BIFF文件（.xls）的庫 - 我是PHPExcel的開發者，所以我建議儘管還有其他庫工作 – 2013-03-03 12:26:25
謝謝，我只是在看，但它幾乎看起來過於複雜，我的需求 – Thejoker123 2013-03-03 12:40:08
