Hey all,
tl;dr
Just one point which JIT/AOT people should consider when dealing with PHP. PHP
is highly dynamic and there are enough use cases which makes it impossible for
a static analyser to infer types accurately without using a top type like mixed.
How would you deal with variable function calls, variable variables,
reflection, dynamic includes etc.
Your inferred types would simply be wrong without using mixed. Consider the
following
function foo(int $a){}
$a = 1; //can be int for sure right?
$b = "a";
$$b = "h"; //oh no, your generated code would crash
foo($a);
Maybe I am wrong and there is a possibility, if so, please let me know, would
be interesting to know.
Cheers,
Robert
