我通過PHP腳本連接到SQL服務器並顯示在瀏覽器中檢索到的內容。通過PHP連接到數據庫並在瀏覽器上顯示內容
的index.html

sqlsrv_close($conn);

所有3個文件都在同一個文件夾中。 瀏覽器只顯示null,我沒有從.php文件中找到任何日誌信息。我的方法正確嗎?我使用正確的JavaScript事件嗎?
裹一切都在一個try/catch(http://php.net/manual/en/language.exceptions.php)如果你的PHP,這將告訴你。 ini設置隱藏了一些錯誤。 – 2014-11-03 08:29:09
其他一切看起來不錯?我如何測試單獨的連接? – Natasha 2014-11-03 08:35:04
如果您只想檢查與連接對象關聯的值,請使用[var_dump](http://php.net/manual/en/function.var-dump.php)。 – 2014-11-04 03:12:35
