Center Block php

I want center block to be displayed based on this.

if ($bbuserinfo[usergroupid]=="4") {
*** show template IsMember
} else {
*** show template NotMember
}

Not I've created two templates called 'IsMember' and 'NotMember' each containing html

Question I have is how to I call the tempate from php script in center block?

try doing this:

PHP Code:

if ($bbuserinfo[usergroupid]=="4") {
    eval("dooutput(\"".gettemplate('IsMember')."\");");
} else {
    eval("dooutput(\"".gettemplate('NotMember')."\");");
}

I guess I've got bigger problems, from reading past posts. VBportal which I'm using center block for hasn't implemented php very well. Refer to this thread -->
