Re: Re: dynamically selecting a function

hmm, there is an intresting way that AFAIK only exists in PHP which is the variable variable and variable function. That is you could have a string to be a function name and then make the call with it in the following manner: $step=1; $func_const_name="step"; $dyn_func=$func_const_name.$step; and then the function call would look like $dyn_func(); // which would result in step1(); How about that? isnt it so beautiful?
