Interesting.
But I was actually doing an assignment using the brace notation:
SomeArray{0} = $somevalue
And, when I did a print_r($SomeArray), it displayed as being an array
with the zero element being the assigned value (if I change the
assignment to SomeArray{99} = $somevalue, then it shows the 99th array
element as holding $somevalue).
So in this situation it seems that braces are equivalent to array
brackets, and are doing something different than string indexing. But
as mentioned, I can't seem to find any documentation indicating this
usage.
This kind of brace usage came up in the context of a certification
practice exam.
