Re: Re: Closures and __FUNCTION__

Well, it's a rather simple bit of logic. First, we define $foo and load it with NULL so that it is available for referencing. Next, in terms of program logic, we create a closure with a lexical ('use') variable of a reference to $foo, which is then assigned to $foo. Thus, the reference to $foo in the closure declaration now points to the closure itself. Recursion is always complicated :P Thanks, Justin Martin Peter Danenberg wrote: > Quoth Justin Martin on Pungenday, the 30th of Discord: >> Apparently it works as such: >> >> $foo = NULL; >> $foo = function($foo) use (&$foo) { >> ... >> } >> >> Still rather hackish, but better than globals I suppose? > > Heh; amazing.
