How to call a function from a string stored in a variable?

Question

I need to be able to call a function, but the function name is stored in a variable, is this possible? e.g:

function foo ()
{
  //code here
}

function bar ()
{
          


        

Answer 1

I dont know why u have to use that, doesnt sound so good to me at all, but if there are only a small amount of functions, you could use a if/elseif construct. I dont know if a direct solution is possible.

something like $foo = "bar"; $test = "foo"; echo $$test;

should return bar, you can try around but i dont think this will work for functions
