That's better, but I don't know if that solves the reentrancy problem. I'm not sure what you mean by dynamic, but I hope that means you can pass a string as name of a callback function and the function is called in the context of a user defined object of a given class. Thatr would mean that the $this references in the method function reference the functions of the class and the variables of the user defined object. >At 15:39 29/06/99 , Andrey Zmievski wrote: >>Manuel Lemos wrote: >> > Unfortunately, some core PHP functions take names of global functions >> > parameters for callback handlers.
