Problems with PASSWORD_ARGON2I in PHP 7.3.6

I read that there is a problem with PHP 7.2 and if you want to use ARGON2 you need to compile php using –with-password-argon2
In my case I'm using PHP 7.3.6
php -v
PHP 7.3.6 (cli) (built: Jun 22 2019 11:43:32) ( NTS )

with Xdebug v2.7.2, Copyright (c) 2002-2019, by Derick Rethans
If I try:
var_dump(password_hash('password', PASSWORD_ARGON2I));
it returns:
PHP Warning: Use of undefined constant PASSWORD_ARGON2I - assumed 'PASSWORD_ARGON2I' (this will throw an Error in a future version of PHP)

what goes wrong with Opcahce and xcache

my environment
ubuntu 14.04 , php 5.5 , nginx 1.76
i am using both opcache and xcache concurrently

i am just wondering can i use both opcache and xcache at the same time .. i dont know whether this allowed or not ? I know that both do almost the same job, but not sure if that would make any difference on the performance and speed.
suggestions invited ? so can i use both ?

I have similar environment (Ubuntu 14.04, PHP 5.6, XCache 3.2, Apache). In my tests when Zend and XCache enabled, the response time is the same of the XCache only. When I disable XCache, and use only Zend OPcache the time resquest reduced in 10ms. Maybe you be try OPCache + Redis (for variables), or use only XCache if the time response not make diference for you.
