如何使用opcache_reset函数？

Question

I have some troubles using the opcache_reset function. I'm working on a Symfony 2 project. I have to use this function, so I created a route who applies this function then it redirect me to the homepage.

But my function want to call the opcache_reset function from my namespace, is there a way to tell that the opcache_reset function is "native" and call the right function?

Here is my error :

 Attempted to call function "opcache_reset" from namespace "AppBundle\Controller".

And here is my function :

public function resetOpcacheAction(Request $request) {
    try{
        opcache_reset()

    } catch(\Exception $e){

    }
    return $this->redirect('homepage');
}

This function resets the entire opcode cache. After calling opcache_reset(), all scripts will be reloaded and reparsed the next time they are hit.

What is opchache ?

OpCache – which stores precompiled script bytecode in the memory. As each PHP script is being compiled at runtime, a part of the execution time gets used for transforming the human readable code into code that can be understood by the machine. A bytecode cache engine like OpCache, APC or Xcache does it only once – during the first execution of a specific PHP file. Then the precompiled script is being stored in memory, which should lead to performance boosts in our PHP applications.

Use like this:-

opcache_reset();
