Calculating a fiscal year in PHP

This code is a straight cut and paste from a comment the php.net page on the strftime() function, credit is due to lamb dot dan at gmail dot com.

There are a couple of bugs in this code which prevent it from working as advertised.

$fystartdate = strtotime($fyStart.$inputyear);
$fyenddate = strtotime($fyEnd.$inputyear);

should be:
$fystartdate = strtotime($fyStart.'/'.$inputyear);
$fyenddate = strtotime($fyEnd.'/'.$inputyear);

And
if($date < $fyenddate){

should be:
if($date <= $fyenddate){

Hey Jason, thanks for your input.

I modified this so heavily to use it that I didn't run into that problem (though I haven't finished debugging so maybe I did.)

I'll look more closely at this when I get a chance, but I appreciate your comment.

Cheers,

Rob
