PHP Strict Typing

A type violation is a run-time exception, not a compile-time error? Cannot believe this.

PHP isn't a compiled language. Exceptions are thrown when the code is loaded into the interpreter and said interpreter notices the error.

No, that is not how it works. PHP is not AST interpreted anymore, there is a distinction between compile-time and run-time. And this error is compile-time, otherwise it would make no sense at all.

Yes and no.

This is a PHP Fatal Error, which will cause execution to stop. But the compiler doesn't compile the entire file in the same way you'd see with other languages. Any code in a PHP file _before_ the type error will still execute just fine, but when the PHP engine hits the error it will fatal and throw a TypeError (along with a stack trace, depending on the verbosity of your configuration).
