That would simply be masking the problem.

'{"xxxxx","yyyyy"}' is a completely valid representation of an array,
but not one you should be getting out of code (because there's no reason
for array_out to toss the extra "s in there). It also doesn't match
either of your other examples.

Please create a stand-alone scenario that demonstrates the problem
you're seeing. I suspect that in the process of doing that you're going
to uncover a bug in your code, but if not then we'll have something
concrete we can look at.
