Send SMTP Mail Via SSL on PHP 7 Environment

I want to send mail by codeigniter Email Library.

Everything works well on PHP 5.4.24 configuration but when i want to migrate to PHP 7 , a lot of SSL certificate problems occurs.

I don't want to install certificate to my machine, only want to send a simple email.

It seems, in 5.4.24, verify_peer is false by default but after php 5.6 verify_peer is TRUE.

And so; how can i set verify_peer to false for Codeigniter Email initialization.

I'm a person from Turkiye. I don't know English very well and i can't write what i want to say sometimes (as now happenes   ).

If i write something by mistake; please don't distress it and try to understand what i want to write.
