Usually module after installed will be create their ini file in /etc/php.d (assumption select php-branch)

My new module added in /opt/php53s/usr/lib64/php/modules/.
Also I made /etc/php.d/new module.ini.

I found it through php -i |grep new module.

But I can't find it in phpinfo.

How can I solve?

Remember:

1. phpXYs (like php53s) is special php for Kloxo-MR panel
2. phpXYm (like php53m) is php for normal website but with special install (run with 'sh /script/phpm-installer')
3. php-branch is normal php for website and install their php module with 'yum install'
4. for phpXYs and phpXYm, install module with 'sh /script/phpm-extension-installer'.

So, what's php module want to installed?.
