Re: [Phpwebsite-developers] php: return array of objects?

[Don S. <do...@se...>]

I failed to note that Manager.getThings passes a reference to the Things 
array, not a copy.  Otherwise the point of keeping the Things array in the 
session would be lost.  But I have tried it with just the copy and I got 
the same error.
