=== Hiding php-fpm version ====
If you run a curl on your website similar to the curl below, does it return php versions? 
\\
This is NOT secure. We will now make a simple change to the php-fpm php.ini file to hide this
==Example curl:==
<sxh bash>
curl -LIsX GET lukeslinux.co.uk | grep php
</sxh>
To hide the php value, find the following value and turn it off:
<sxh bash>
expose_php = On
</sxh>
Restart php-fpm and you are done. Test again by rerunning the curl command.
