note 51707 deleted from function.array-walk by nlopess

Note Submitter: PHP Novice ---- While Hayley's comments about pass-by-reference will work for now, this is a deprecated feature. I've been working with array_walk in a class and inside the callback I want to alter a member field of the object. What I've discovered is that the $this object present during the invokation of the callback is a copy of the original object. This of course means that your modifications will be lost when you return from the array_walk call. The only solutions I've come up with for this is to use the runtime pass-by-reference mechanism to provide a reference to the field I want to modify and get the deprecation warning or break the encapsulation of my class by using a global. (YUCK!) Can a PHP guru show me what I've missed (if anything) regarding this issue?
