Not sure if this is a bug or not, but I can't find any 
reference to it in the documentation/user comments/FAQs

Basically, if you build an associative(ish) array like 

$period = -24;
for ($i=$period; $i<=0; $i++) {
	$data[$i] = $myvalues[$anotherindex];

It works ok, the array contains (in order) elements with 
the inidices -24 to 0.

But, if $period is decreased so that over 25 elements are 
introduced, the order goes off...

basically elements with indices -24 to 0 are fine, but all 
the other ones come, in order, _after_ index 0.

Any ideas?

I.M.O. negative integer indices are not supported. It is just a side-effect of the implementation that it works.

I haven't seen ANY language supporting negative array-indices.

You can use the real assosiative version though:

$data["$i"] = ...

And don't forget to use the same syntax when collecting the data.

IIRC PHP converts numeric strings in array indices to numbers, so array( "1" => "foo" , "2" => "bar" ) actually creates array( 1 => "foo" , 2 => "bar" ). IE the proposed method won't work.
