@jboadas your gpg output indicates it only processed one key, I suggest you check that you copied the command correctly with the two arguments or you can just import the missing key
$ gpg --keyserver hkp://hkps.pool.sks-keyservers.net --recv-keys FE857D9A90D90EC1
With that said, I suggest you upgrade to PHP 7 because PHP 5.6 security updates will stop in 2 months.

PHP 5.6 will stop getting security updates in January 2019. Consider upgrading to PHP 7 now

PLEASE READ : For those who are getting "unknown public key" errors, this is NOT caused by this package. It means GPG is not configured to fetch public keys automatically (which is normal by default)
Please read the instructions at https://wiki.archlinux.org/index.php/Makepkg#Signature_checking
The easiest way to overcome this is to manually import the keys from a keyserver :

foxxx and I have been working together and this package can now be installed along PHP 7 from the official repos.
Everything has been moved into separate directories :
Config : /etc/php56
Extensions : /usr/lib/php56/modules
Binaries : /usr/bin/php56, /usr/bin/php56-cgi, /usr/bin/phar56, etc.
If you were previously using this as a replacement for php7, you'll have to adjust the new configuration files in /etc/php56/ to reflect the current ones in /etc/php/.
Apache module (provided by php56-apache) also has a specific configuration and CAN NOT cohabit with php7_module. Use php-fpm, fcgi or cgi if you need both versions.
The apache module is installed as libphp56.so, so you should use the following lines your httpd.conf :
# Load php 5.6 module
LoadModule php5_module modules/libphp56.so
# Use it for .php extensions
Include conf/extra/php56_module.conf
Please let me know if you encounter any problem or have a suggestion.
