How to enable JIT for OPcache in PHP 8

Introduction

In version 8 of PHP, they introduced  a JIT compiler for PHP's core. With ZendOPcache, how do I enable this?

Procedure

First, make sure you have OPcache installed. 

yum install ea-php80-php-opcache

Next, modify the main php.ini file in/opt/cpanel/ea-php80/root/etc/php.ini

You will need to add opcache.jit_buffer_size=16M to the the php.ini file. 

Additional options can be configured for JIT as well. Please review the official PHP documentation for a full list of options.
