symfony2致命错误无法重新声明类

Question

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.

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

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).

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.

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

I only have it once?!

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

Answer 1

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

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

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

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.

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

Answer 2

redeclare class - 可能有两个同名的课程

Answer 3

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 :/)

Answer 4

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.

Answer 5

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

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

Without the use directive, it Worked

Answer 6

Personally, I juste removed cache manually and it worked

rm -rf app/cache/*

Clearing cache was not fixing my problem.
