PHP accelerator installed but symfony 3 not recognized it

Question

When i install symfony, it recommeneded me:
Install and/or enable a PHP accelerator (highly recommended).

I installed apcu according to http://www.ivangabriele.com/php-how-to-install-php-accelerator-in-xampp/

APCu installed successfully and phpinfo() show it enabled but symfony still get me this message:
Install and/or enable a PHP accelerator (highly recommended).

Answer 1

Thanks for that info @ceejayoz. I wonder if you have a link that describes why an accelerator in PHP 7.0 is unnecessary, I would appreciate that.

Otherwise Jinx, you can try php70u-opcache. That's what I used:

yum install php70u-opcache

This is on CentOS, you may have a different Linux distro, so the commands may be different. Also it may not be 'php70u'. But when you run php bin/symfony_requirements , you won't get the message about the accelerator.
