Ok, this is ugly but if you name your functions by their probability:
function _0_234321()
{ // test function
$probability = 0.234321;
echo "$probability<br>";
...
}
$probability = 0.234321;
$func_to_call = '_'.str_replace('.','_',$probability);
//echo $func_to_call.'<br>';
call_user_func($func_to_call);
.... or am I missing the point?
