FPDF頁不完全加載在Internet服務器，但正確工作在本地服務器

但網頁不負載。 記住一件事。它在我的本地服務器上正常工作並正確生成輸出。但是當我上傳在互聯網服務器上的腳本，它不顯示任何輸出。

Answer 1

該方案有至少三個外部的依賴關係：

• ../fpdf/fpdf.php
• ../__accinfo.php
• dbinfo.inc

，他們都在不同的目錄。你確定這兩臺機器都具有這些匹配嗎？然後所有這些包括等等？

看來奇怪的是，這些線是有序的，因爲它們是：

$link_id=mysql_connect($dbhost, $dbusername, $dbuserpassword) ... 
include_once "dbinfo.inc"; 

哪裏$db *定義的變量？ （但願../__accinfo.php）

Answer 2

檢查DBHOST，數據庫用戶名和DBPASSWORD如果它從本地服務器的數據數據符合您的Internet服務器

常見的錯誤是未能更新到互聯網服務器數據

mysql_connect($dbhost, $dbusername, $dbuserpassword)
