Keeping PHP to a minimum / 2015-05-04

I noticed the recent upgrades left some PHP scripts non-working. The default is now to disable PHP in userdirs, via:

    # To re-enable php in user directories comment the following lines
    # (from  to .) Do NOT set it to On as it
    # prevents .htaccess files from disabling it.
    <IfModule mod_userdir.c>
        <Directory /home/*/public_html>
            php_admin_value engine Off
        </Directory>
    </IfModule>

I decided I want some PHP in userdirs, but while I was working on this configuration I want to turn the default around: disable the PHP engine in the global configuration and only enable it on those sites where I need it for the site. So now /etc/php5/apache2/php.ini has:

; Enable the PHP scripting language engine under Apache.
engine = Off

And some sites that need it have in the VirtualHost config:

# enable php
    php_flag engine 1
    <FilesMatch "\.ph(p3?|tml)$">
        SetHandler application/x-httpd-php
    </FilesMatch>
