PHP Typo3 4.7 基于 extbase 的扩展中的错误 "Cannot redeclare class"
PHP error "Cannot redeclare class" in extbase-based extension of Typo3 4.7
我使用 extbase 框架为 Typo3 4.7 创建了一个扩展（实际上，它是为 Typo3 6.2 创建的，但我正在尝试向后移植它）。我已经从核心中删除了所有名称空间并检查了 TYPO3 - Call another repository。但是，我遇到调用前端插件导致 PHP 错误 PHP Fatal error: Cannot redeclare class [...]\ProjectController in [...]/ProjectController.php on line 127 的问题（第 127 行是 class 的右大括号）。在我的插件中，我没有任何 require/include 除了 "dynamicConfigFile"s.
有问题的控制器使用这样的依赖注入：
/**
* projectRepository
*
* @var Tx_MyExtension_Domain_Repository_ProjectRepository
* @inject
*/
protected $projectRepository = NULL;
/**
* sfbRepository
*
* @var Tx_myExtension_Domain_Repository_SFBRepository
* @inject
*/
protected $sfbRepository = NULL;
我是 运行 PHP 5.5.14。如果我将 "Tx_..." 内容改为使用名称空间，则整个代码适用于 Typo3 6。
到目前为止，我只找到一个关于这个问题的网站 (https://forum.typo3.org/index.php/t/203725/)，它说使用依赖注入而不是 t3lib_div::makeInstance 已经解决了这个问题。但是，我已经在使用依赖注入了。
此外，如果我在 class 的声明之前添加 print_r(get_declared_classes());，它 不会 打印有问题的 class，即好像没申报。
有没有人遇到过这样的问题？我还能做些什么来解决这个问题？

编辑： 与此同时，我尝试使用命名空间并删除它们——两种情况下的结果都是一样的。此外，删除依赖注入也没有效果。如果我在声明周围添加 !class_exists() 检查，脚本不会崩溃，但会引发异常并且 Typo3 抱怨 class 未在日志中定义。几乎就好像 class 以某种方式存在，但不能使用或有所不同...
编辑： 我现在已经重命名（希望）所有 classes 和注释以匹配 extbase 命名方案。但是，错误已移，调用堆栈现在如下所示：

查看调用堆栈时，我想知道 http://php.net/manual/de/function.spl-autoload-call.php 中描述的 spl_autoload_call 的 "inheritance problem" 是否与该问题有关。
另一个更新： 现在我自己的代码在调用堆栈中，我能够找到问题的根本原因。我现在可以注释掉对第二个存储库 ($this->sfbRepository->findByUid($id);) 的调用，并且插件正在运行。导入看起来像：
/**
* sfbRepository
*
* @var Tx_MyExtension_Domain_Repository_SFBRepository
* @inject
*/
protected $sfbRepository = NULL;
存储库的声明是：
class Tx_MyExtension_Domain_Repository_SFBRepository extends \Tx_Extbase_Persistence_Repository {
}
最终更新： 最后一个只是（已更改）class 名称中的错字...
为了避免自动加载的麻烦，即使您不使用命名空间，也需要坚持 Extbase 命名约定：
Tx_MyExtension_Controller_ProjectController
应该是以下文件：
EXT:my_extension/Classes/Controller/ProjectController.php
(注意在目录结构中转换为下划线的大驼峰扩展名。)
如果您不知道TYPO34.x中的哪个6.2class和哪个class，您可以在“Legacy Classes for IDE”文件中搜索。请记住也要适应 @inject 注释，因为注入是基于注释的：
* @var Tx_MyExtension_Domain_Repository_ProjectRepository
* @inject
我使用 extbase 框架为 Typo3 4.7 创建了一个扩展（实际上，它是为 Typo3 6.2 创建的，但我正在尝试向后移植它）。我已经从核心中删除了所有名称空间并检查了 TYPO3 - Call another repository。但是，我遇到调用前端插件导致 PHP 错误 PHP Fatal error: Cannot redeclare class [...]\ProjectController in [...]/ProjectController.php on line 127 的问题（第 127 行是 class 的右大括号）。在我的插件中，我没有任何 require/include 除了 "dynamicConfigFile"s.
有问题的控制器使用这样的依赖注入：
/**
* projectRepository
*
* @var Tx_MyExtension_Domain_Repository_ProjectRepository
* @inject
*/
protected $projectRepository = NULL;
/**
* sfbRepository
*
* @var Tx_myExtension_Domain_Repository_SFBRepository
* @inject
*/
protected $sfbRepository = NULL;
我是 运行 PHP 5.5.14。如果我将 "Tx_..." 内容改为使用名称空间，则整个代码适用于 Typo3 6。
到目前为止，我只找到一个关于这个问题的网站 (https://forum.typo3.org/index.php/t/203725/)，它说使用依赖注入而不是 t3lib_div::makeInstance 已经解决了这个问题。但是，我已经在使用依赖注入了。
此外，如果我在 class 的声明之前添加 print_r(get_declared_classes());，它 不会 打印有问题的 class，即好像没申报。
有没有人遇到过这样的问题？我还能做些什么来解决这个问题？

编辑： 与此同时，我尝试使用命名空间并删除它们——两种情况下的结果都是一样的。此外，删除依赖注入也没有效果。如果我在声明周围添加 !class_exists() 检查，脚本不会崩溃，但会引发异常并且 Typo3 抱怨 class 未在日志中定义。几乎就好像 class 以某种方式存在，但不能使用或有所不同...
编辑： 我现在已经重命名（希望）所有 classes 和注释以匹配 extbase 命名方案。但是，错误已移，调用堆栈现在如下所示：

查看调用堆栈时，我想知道 http://php.net/manual/de/function.spl-autoload-call.php 中描述的 spl_autoload_call 的 "inheritance problem" 是否与该问题有关。
另一个更新： 现在我自己的代码在调用堆栈中，我能够找到问题的根本原因。我现在可以注释掉对第二个存储库 ($this->sfbRepository->findByUid($id);) 的调用，并且插件正在运行。导入看起来像：
/**
* sfbRepository
*
* @var Tx_MyExtension_Domain_Repository_SFBRepository
* @inject
*/
protected $sfbRepository = NULL;
存储库的声明是：
class Tx_MyExtension_Domain_Repository_SFBRepository extends \Tx_Extbase_Persistence_Repository {
}
最终更新： 最后一个只是（已更改）class 名称中的错字...
为了避免自动加载的麻烦，即使您不使用命名空间，也需要坚持 Extbase 命名约定：
Tx_MyExtension_Controller_ProjectController
应该是以下文件：
EXT:my_extension/Classes/Controller/ProjectController.php
(注意在目录结构中转换为下划线的大驼峰扩展名。)
如果您不知道TYPO34.x中的哪个6.2class和哪个class，您可以在“Legacy Classes for IDE”文件中搜索。请记住也要适应 @inject 注释，因为注入是基于注释的：
* @var Tx_MyExtension_Domain_Repository_ProjectRepository
* @inject
