Let's assume you alread have a old system running with php5.3

# 1 - Install Remi and Epel repository

rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm

# remove/comment every configuration on /etc/httpd/conf.d/php.ini

# Create the following files:

/var/www/cgi-bin/php5.fcgi
#!/bin/bash
PHPRC="/etc/php.ini"
PHP_CGI=/usr/bin/php-cgi
PHP_FCGI_CHILDREN=8
PHP_FCGI_MAX_REQUESTS=3000
export PHPRC
export PHP_FCGI_CHILDREN
export PHP_FCGI_MAX_REQUESTS
exec $PHP_CGI

/var/www/cgi-bin/php7.fcgi
#!/bin/bash
PHPRC="/etc/opt/remi/php72/php.ini"
PHP_CGI2=/opt/remi/php72/root/usr/bin/php-cgi
PHP_FCGI_CHILDREN=8
PHP_FCGI_MAX_REQUESTS=3000
export PHPRC
export PHP_FCGI_CHILDREN
export PHP_FCGI_MAX_REQUESTS
exec $PHP_CGI2


# make executable and set the owner:
chmod a+x /var/www/cgi-bin/*
chown apache:apache /var/www/cgi-bin/*


# let's keep the php5 on default por 80 and configure php7 on port 8070

# Remove any VirtualHost's configuration with port 80 or 8070, and add the following on /etc/httpd/conf/httpd.conf

Listen 80 
Listen 8070

<VirtualHost *:80>
    DocumentRoot /var/www/html
    ScriptAlias /cgi-bin/ "/var/www/cgi-bin/"
    <Directory /var/www/html >
        Options +Indexes FollowSymLinks +ExecCGI
        AddHandler php5-fastcgi .php
        Action php5-fastcgi /cgi-bin/php5.fcgi
        AllowOverride All
        Order allow,deny
        Allow from All
    </Directory>
</VirtualHost>

<VirtualHost *:8070>
    DocumentRoot /var/www/html
    ScriptAlias /cgi-bin/ "/var/www/cgi-bin/"
    <Directory /var/www/html>
        Options +Indexes FollowSymLinks +ExecCGI
        AddHandler php7-fastcgi .php
        Action php7-fastcgi /cgi-bin/php7.fcgi
        AllowOverride All
        Order allow,deny
        Allow from All
    </Directory>
</VirtualHost>


# restart apache
service httpd restart

Now port 80 is php5 and port 8070 is php72
