how to install php thread safe in rhel7 to support httpd thread based MPM?

im using phpmyadmin and some other php based code i developed.
i want to use the MPM worker \ event that are thread based.
it seem that the default version provided in my repo php-5.4.16-42.el7.x86_64 is not thread supported so i cant use it in my httpd.
i know i can use prefork but for better performance i want to use worker\event work.

i search a bit and found that there is php that support thread.
is rhel 7 support that? how and from where i can install it?
