How to install Zeromq for xibo 1.8


I try to Install Zeromq for xibo with xampp. I used several procedures but it does not work.
currently I have in my repertoire: C:\xampp\apache\bin\libzmq.dll & C:\xampp\php\ext\php_zmq.dll
I added in php.ini the ligne extension=php_zmq.dll
but when I run xibo, Zeromq does not work.

XAMPP v3.2.2
PHP 5.2
XIBO 1.8


Xibo CMS version 1.8 requires PHP 5.6 or higher. can you first upgrade your PHP and then try ZeroMQ again?

I’ve also included links to the XMR and Prepare your Environment manuals:

Many Thanks.
