I suppose, there is a problem with PH7_OP_STORE instruction.
$x = '';
var_dump(is_string($x));
The above example also fails. It shows:
bool(FALSE)
instead of:
bool(TRUE)
I suppose, there is a problem with PH7_OP_STORE instruction.

I think it takes the value as it comes from the compiler. From what I checked, it forces type to NULL if string is empty. Seems easy to fix.
Let me check if I can fix this.
