[swx] Catching PHP parse errors on Flash

[Aral Balkan]

Hi Fabrício,

That's interesting -- thanks so much for sharing.

I'm assuming you're working with pre v.1 as you're returning this in
result[0] instead of result.

I'm going to look at what you're doing in more detail when I get a moment.

Take care,
Aral
