Live preview is wrong

[Bilge]

How does live preview (not) work? The problems I'm seeing are that the results from live preview are bogus and you only get the real result after clicking the eval() button. This is highly misleading and problematic.

Examples

echo PHP_INT_MAX * 10;

Live-preview	eval();
21474836470	9.2233720368548E+19

echo (int)(PHP_INT_MAX * 10);

Live-preview	eval();
-10	0

As you no doubt concluded yourself, the live preview is 32 bits, the non-live are 64 bits - so this is basically a duplicate of #19 :)

Actually, I had not concluded that, so thanks for the clarification!

But my question about live preview still stands: how does it work? I suppose I could try digging into the source, but I hoped it would be easier to just ask. The response seems near-realtime and I was just naturally curious how that is even possible?

I guess it's just using this: https://github.com/seanmorris/php-wasm.
