The original: "PHP is easy to learn. Golang is as easy as PHP!"

Some str_replaces:

"Ruby is easy to learn. Golang is as easy as Ruby!"

"Clojure is easy to learn. Golang is as easy as Clojure!"

"Python is easy to learn. Golang is as easy as Python!"

Hmm, I'm still not feeling offended. Are you sure this might not be some sort of inferiority complex at play? I think a lot of PHP developers get needlessly offended whenever we talk about PHP, positive or negative.
