symfony2致命错误无法重新声明类

好吧，我已经做了两个小时了，我看到其他人也犯了这个错误，但我似乎无法将他们的原因/解决方案与我的相匹配。

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

终端给出了一个更好的错误消息，将我指向它报告有问题的实际类的结束子句（试图重新声明）。

如果我删除或重命名文件companyControlle.php，它会抛出一个Symfony2错误，说它在寻找类，但没有在预期的位置找到它。

如果我把文件放回原处，apache会抛出一个php错误，说类companyController不能重新声明。

我只有一次？！

这是全班同学。。。如果有人有耐心帮我。。。
