How to enable PHP Exteions?

Hi

I am trying to install php-imap.

I used command:

yum install php70-php-imap

And it installed it.

After that i restart my httpd service by

systemctl restart httpd.service

And I used command

php -m

and there’s no extenion named “imap”.

Cant believe it.

I tried to install again and it says

Package php70-php-imap-7.0.33-9.el7.remi.x86_64 already installed and latest version Nothing to do

---

On my server I have old php 5.4 and 5.6 too.

Can it be about that? How can I enable that extenion?

Im looking for php.ini file and there’s no line about “imap”.

Need some help. Thanks.
