PHP語法錯誤問題

嗨，我有以下目錄結構：PHP語法錯誤問題

Main Folder -> Classes -> user_classes

都互相嵌套。我有內部類目錄下面的文件

always_include_top.php 
custom_error_handler.php 
config.php 
database.php

外面的database.php中文件如下：

<?php 
include_once("always_include_top.php"); 

include_once("config.php"); 
include_once("custom_error_handler.php"); 

include_once ("user_classes/newDatabase.php"); 

class Database extends newDatabase 
{ 

// some more code... with extra functions 
    public function dbBackUp($backupfile = NULL) 
    { 
     //code... 
    } 
} 
?>

我在用戶user_classes目錄下面的文件

newDatabase.php

此文件的代碼示例是

<?php 
include_once("../always_include_top.php"); 

include_once("../config.php"); 
include_once("../custom_error_handler.php"); 
error_reporting(E_ALL); 

class newDatabase 
{ 
    // my code goes here 
} 

?>

爲什麼我會收到以下錯誤類/ database.php中（沒有在類錯誤/ user_classes/newDatabase.php）

Warning: include_once(../always_include_top.php) [function.include-once]: failed to open stream: No such file or directory in E:\wamp\www\greeting_cards\adm\classes\user_classes\database.php on line 2

Fatal error: Cannot redeclare class Database in E:\wamp\www\greeting_cards\adm\classes\database.php on line 12

我想這兩個文件單獨編譯。因爲我會根據頁面類型將文件包含在其他文件中。這裏包括什麼問題？

你在'user_classes/newDatabase.php'中有什麼？ – MGwynne

@MGwynne我已經把它放在「*我在用戶user_classes目錄中有以下文件*」部分。看看 – footy

我想你可以將'include_once（）'database.php中的路徑更改爲'include_once（「classes/always_include_top.php」）;' – jeni

當您使用include_once()時，它不會更改到特定文件所在的目錄並在那裏執行它，它會在當前文件的上下文中執行該文件的內容。所以，類/ user_classes/database.php就像在classes文件夾中一樣執行。「..」指的是在這種情況下的主文件夾，所以它正在查找主文件夾中的前三個文件。這些文件不在主文件夾中，因此會給出警告。
