You can avoid the E_NOTICE using a reference, but it can have undesired
side effects. For example, if you pass $x[5] by reference (whether to
an internal function or a user defined function), $x[5] will be
"created" and set to NULL. To avoid this side-effect, don't use the
reference and instead use @$x[5] as the first argument to the function.
(but DO NOT use @$x[5] as an argument to a function that takes a
reference - it may cause a crash/corruption later.)
