Have a look here:
http://guru-host.eu/en/Zimbra-Virtual_machine_with_Zimbra_installed.html
There is an out of the box Zimbra installation on a VMware virtual machine and there are also instructions on how to get backup your Zimbra.

Frankly, I couldn’t care less that the switch statement is X milliseconds faster or slower in Y fringe scenarios.

If you’re replacing your if statements with switch statements and each case has a break after it, you’re misusing the language’s features.

In my code, scenarios where switch is the right tool for the job are extremely rare and, when I find myself in such a position, I often ask myself if there’s a better way to do what I’m trying.

This vaguely reminds me of explaining to someone why you don’t use the bold tag in markup, you use the strong tag.

This is all completely beside preference. I have no idea how anyone could find a switch statement prettier than an if/else. PHP has C-style brackets for a reason.

Hmm, what was the setup (os, php v, etc), one wonders. Tested 100,000,000 iterations with php 5.3.2 on windows+freebsd+ubuntu server (both scripts noticeably slower in windows – surprise!). Very little difference. Have they changed if vs switch behavior perhaps? @pj: I’d guess yes. Do the same. Easier to read and make changes (debugging e.g.)

Nice Howto about the zimbra setup, I wonder how do you do the backup? Currently, I set it up under my xen server, the zimbra is one of the xen guest dumU, and its /opt/zimbra is a logical volume from the host. If you use rsync, what is the correct paramaters for it ?

rsync -av /source/ /target

rsync -avHK /source/ /target

Thanks a lot! I got to the “PHP Switch” chapter of PHP Basic course at W3Schools.com and immediately wondered about (and googled) the difference between if vs switch. Thanks to you I learned when to use each one!

Also, beginner question: I see you use curly braces { and } even when you only have 1 line to be executed for a certain if or elseif statement. I assume you do this just out of habit?
