Stable? Big e-shop I wrote in 2005 in PHP works without any compatibility issues until today. No need to re-compile anything, to fix bugs in the runtime, etc. Ruby was some obscure language just gaining acceptance back then, node didn't exist, golang didn't exist, C# has just invented iterators. PHP showed over the years that it was a stable and painless surface to build on. And I don't see it changing.
