Is it possible to write strictly typed PHP code?

Question

For example, is it possible to write code like this:

int $x = 6;
str $y = \"hello world\";
bool $z = false;
MyObject $foo = new MyObject();

Answer 1

You could use h2tp transpiler to transpile HACK code to PHP:

You can do this thanks to Facebook Team and HACK Language.

Visit http://hacklang.org and http://hhvm.com for more info.

If you want to code directly in Hack + HHVM environment you can also use Facebook's internal IDE Nuclide
