I need to reference a variable, that the variable is set dynamically by some php code.. to exaggerate on the matter...

I need to set "$isie" based upon a php if statement, and then echo $isie within the smarty template.

I realize to reference a php set variable in smarty, its {$isie}.. but which file should i put this PHP code in to be parsed before head.tpl? Thanks!
