Need zend on my domain but it seems not to load the module

Dear all.

For a aplication i need the Zend loader to work.
My current OS is:
lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 14.04.4 LTS
Release: 14.04
Codename: trusty

Current php version:
php -v
PHP 5.5.9-1ubuntu4.17 (cli) (built: May 19 2016 19:05:57) Copyright © 1997-2014 The PHP Group
Zend Engine v2.5.0, Copyright © 1998-2014 Zend Technologies with Zend OPcache v7.0.3, Copyright © 1999-2014, by Zend Technologies

For this I used the following guide:
Please see this small guide
I placed the 2 “.so” files in this locatation: /usr/local/zendoptimizer
which are:
-rw-rw-r-- 1 root root 163069 jul 25 10:31 opcache.so (Permission 664)
-rwxr-xr-x 1 root root 1471541 jul 25 10:31 ZendGuardLoader.so (Permission 755)

Than I have added to this file : /home/mydomain/etc/php5/php.ini the following lines at the bottom of the file:
[Zend]
zend_extension=/usr/local/zendoptimizer/ZendGuardLoader.so
zend_loader.enable=1

than I restart the apache using this command: /etc/init.d/apache2 restart
once restarted i do php-m and see that the module is NOT loaded.

Zend OPcache
zip
zlib

[Zend Modules]
Zend OPcache

I don´t see the module loaded. even when restarten apache 1000 times
I propbalbly am missing something.
Can aynone help me out with this please?

Hoping to hear from you.
Regards,
Paco

In that guide it say you should copy only one file ZendGuardLoader.so in /usr/lib/php5/:

cp ZendGuardLoader.so /usr/lib/php5/

Dear Diabolico.
Many thanks for your suggestion, tried it already but again, no luck
The reason for placing it some where else is due what I read here: https://www.virtualmin.com/node/19355 , Suggested by Eric
So, if you put files in there, a normal user wouldn’t be able to see it.
My recommendation would be to put your Zend Optimizer files somewhere globally accessible… perhaps in /usr/local/ZendOptimizer.
Also, you can look in the Apache errors logs, $HOME/logs/error_log, for clues as to why things aren’t working.

So it seems I am still missing some things…
Any other sugestion, please?

Hoping to hear from you…
