using a variable and conditional in template

[da prez]

i wrote a simple query that returns a numeric value or 1, 2, or 3 etc.

what i want to do is use this variable to make a conditional.
$string6 is my variable and it does return proper #
can i use this variable in a conditional within a template to do something like this ??

example:

<if $string6="1">Hello</if>

<if $string6="2">Goodbye</if>

how would i go about it ?

i have a shoutcast radio station up,
and based on which dj is online i want to show diff info.
