Use of reference "%s" as array index
(W misc) You tried to use a reference as an array index; this probably isn't what you mean, because references in numerical context tend to be huge numbers, and so usually indicates programmer error.
If you really do mean it, explicitly numify your reference, like so:
$array[0+$ref]. This warning is not given for overloaded objects,
either, because you can overload the numification and stringification
operators and then you assumably know what you are doing.
