Install opcache for php on Fedora

OPcache improves PHP performance by storing precompiled script bytecode in shared memory, thereby removing the need for PHP to load and parse scripts on each request #1. OpCode Caches are a performance enhancing extension for PHP. They do this by injecting themselves into the execution life-cycle of PHP and caching the results of the compilation phase for later reuse. It is not uncommon to see a 3x performance increase just by enabling an OpCode cache #2.

To install on Fedora:

yum install php-opcache 

To turn on the opcache module, restart httpd service:

/bin/systemctl restart  httpd.service 

You will be able to see opcache running information in phpinfo.php.
