php symfony2 致命错误无法重新声明类

symfony2 fatal error Cannot redeclare class

提问by Matt Welander

Ok, I've been at this for two hours now and I see some other people have had this error, but I can't seem to match their causes/resolutions with mine.

好的，我已经在这里呆了两个小时，我看到其他一些人也遇到了这个错误，但我似乎无法将他们的原因/解决方案与我的相匹配。

Fatal error: require() [function.require]: Cannot redeclare class companycontroller in /var/www/biztv_symfony/vendor/symfony/src/Symfony/Component/ClassLoader/DebugUniversalClassLoader.php on line 55

致命错误：require() [function.require]：无法在第 55 行的 /var/www/biztv_symfony/vendor/symfony/src/Symfony/Component/ClassLoader/DebugUniversalClassLoader.php 中重新声明类 companycontroller

The terminal gives a better error message pointing me to the end clause of the actual class that it reports having trouble with (trying to redeclare).

终端给出了一条更好的错误消息，将我指向它报告有问题（试图重新声明）的实际类的结束子句。

If I remove or rename the file companyController.php it throws a Symfony2 error saying that the it went looking for the class but didn't find it where it was expected.

如果我删除或重命名文件 companyController.php，它会抛出一个 Symfony2 错误，说它去寻找类，但没有在预期的地方找到它。

If I put the file back in its place, apache throws a php error saying that the class companyController can't be redeclared.

如果我将文件放回原处，apache 会抛出一个 php 错误，指出类 companyController 无法重新声明。

I only have it once?!

我只有一次？！

Here is the entire class... if anyone has patience to try and help me out...

这是整个班级...如果有人有耐心尝试帮助我...

So, turns out that was a clumpsy typo by moi there.

所以，事实证明这是 moi 那里的一个笨拙的错字。

But for anyone else who runs into this error message in Symfony2:

但是对于在 Symfony2 中遇到此错误消息的任何其他人：

Fatal error: require() [function.require]: Cannot redeclare class...

致命错误：require() [function.require]：无法重新声明类...

Here is a hint: check if you have accidentally deleted or typo:ed the namespace in the file that contains the definition of the class that php claims it is trying to re-define.

这是一个提示：检查您是否不小心删除或错别字：修改了文件中的命名空间，该文件包含 php 声称它试图重新定义的类的定义。

The php error message doesn't really give you a clue to look for that... =)

php 错误消息并没有真正为您提供寻找该信息的线索... =)

Personally, I juste removed cache manually and it worked

就个人而言，我只是手动删除缓存并且它有效

rm -rf app/cache/*

Clearing cache was not fixing my problem.

清除缓存并没有解决我的问题。

redeclare class - Likely there is tow classes with the same name

重新声明类 - 可能有两个同名的类

Sometimes, if you got seduced by copy/paste, check your classnames, namespaces and for other "typos" that could have happened. (copy/paste is the devil of programming :/)

有时，如果您被复制/粘贴所吸引，请检查您的类名、命名空间以及其他可能发生的“错别字”。（复制/粘贴是编程的魔鬼：/）

回答by Arild

Similar to other answers, in my case I had renamed the class but not the containing file. Every class should be declared in a file with the same name. So check that, too.

与其他答案类似，在我的情况下，我重命名了类，但没有重命名包含文件。每个类都应该在同名的文件中声明。所以也检查一下。

回答by Corni

In my case, it was a usestatement under the namespace which used the same classname (but another path).

在我的例子中，它是use命名空间下的一个语句，它使用了相同的类名（但另一个路径）。

namespace Bsz\RecordTab;
use \Bsz\Config\Libraries; // I used  this in constructor
class Libraries 
{
...
}

Without the use directive, it Worked

没有使用指令，它有效
