Solaris/apache/PHP update

Having just updated to the latest version of Solaris and its packages, I've had a bit of pain due to apache going from 2.2 to 2.4 and also a php upgrade.

Much thrashing about has ensued, but the key points were;

Apache
httpd.conf 
Some of the syntax has changed. The old approach of lift and shift no longer works so lines have to be copied over individually and updated as per the comments.

.htaccess
The format of allow,deny lines has changed so any local .htaccess files need updating.
For more info see https://httpd.apache.org/docs/2.4/upgrading.html

Running as none webservd user
Adjust SMF properties with svccfg and change log file ownership as required.

PHP
Lots of pain here, which I think boiled down to all extensions being commented out by default.
Fix was to uncomment all lines in /etc/php/5.6/conf.d/extensions.ini
