Could you please elaborate a bit more on what the bug is? ------------------------------------------------------------------------ [2011-05-20 15:46:36] mlvl dot jr at gmail dot com Description: ------------ There probably should be an explicit reference to this: "While not being strictly an assignment by reference, expressions created with the language construct array() can also behave as such by prefixing & to the array element to add. The page also explains your why your first code behaves like it does: Note, however, that references inside arrays are potentially dangerous. Doing a normal (not by reference) assignment with a reference on the right side does not turn the left side into a reference, but references inside arrays are preserved in these normal assignments. This also applies to function calls where the array is passed by value."
