Is PHP type safe?
By this definition, PHP will never be type safe (PHP’s compiler hardly prohibits any type errors). But that definition also isn’t particularly useful to the majority of developers. Type safety measures the ability of available language tooling to help avoid type errors when running code in a production environment.
