thanks for the tip but i am sure you mean:
eval("\$return = \$function(\$input);");
otherwise the variables gets expanded before they get to eval and i end up
with a syntax error. i found a solution (hopefully) with:
if(function_exists($function)){
eval('$return = $function($input);');
}else{
// function does not exists
}
which works quit nicely for now. not sure if that's a good thing to do.
thanks!
