使用PHP和mySQL進行Android登錄

Question

我正在使用android應用程序，因爲登錄部分在eclipse上沒有檢測到錯誤，但是連接並未使用mySQL數據庫建立。這裏的日誌文件

沒有看到有問題的代碼很難，沒有任何真正肯定地說，但這個錯誤看起來像從頁面本身到來。確保你連接到正確的URL並給出所有參數。它獲得JSON解析的事實表明它至少連接到該網站。

此錯誤

<b>Parse error</b>: syntax error, unexpected '{' in <b>C:\Program Files\EasyPHP-12.0\www\Android\Connection.php</b> on line <b>36</b><br /> 

幾乎肯定從PHP本身。
