Hi, Vincent,
 Thanks for the answer.
 I am interested in formmail function using PHP, is there a proper and safe
 solution on XWiki already?

  Hi, Vincent,
 How to set  up PHP on XWiki farm? Not my own server. Is it possible?

 Since you asked for a wiki on 
myxwiki.org I guess the question is whether you
 can use it on that farm. The answer is no. The reason is that we're not allowing
 users to use script macros such as PHP, jython, ruby and groovy. Only the
 Velocity macro is made available. The reason is that those script macros are
 very powerful and anyone could easily break the security of the farm or do
 dangerous things (like wipe all data on the server's hard disk for example).
 Thus we've not giving programming rights to users on the myxwiki farm.
 In the future we'll be working on defining a way to be able to restrict what you
 can with programming languages so that only edit rights would be necessary to
 use them in a "sandbox mode" but we're not there yet.
 Right now the only way for you to use the PHP macro is by installing XWiki
 Enterprise or XWiki Enterprise Manager on your own machines (and thus have
 programming rights).
 Sorry about that.
 Thanks
 -Vincent
