fix: remove @ error suppression from echo/fwrite/fflush calls

`@echo` is invalid PHP syntax — echo is a language construct,
not a function, so the @ operator cannot be applied to it. This
causes a parse error on some PHP versions/runtimes.

The recursion guard ($in_log) added in 1.1.7 already prevents
infinite loops when STDOUT/STDERR is broken, so @ suppression
is unnecessary. Remove @ from echo, fwrite, and fflush calls.

Version bumped from 1.1.8 to 1.1.9.
