Sorry, I agree with Jon on this one.
I make it a habit not to delete entries in a foreach() loop. Rather, I
build an array of keys I want to delete, and after the loop ends, delete
the entries from my delete array.
I don't know whether an operation like this is guaranteed to work in PHP
- I've never seen it documented, so I suspect not. And just because it
works in one release under a certain set of conditions is not a
guarantee it will work on another release or under different conditions.
