I think an important part of tech is continuously learning.

e.g. if you can't find jobs as a PHP developer, but you see there are many jobs for (say) NodeJS web development, or Golang API development, you may need to learn some things, but that can build upon how you did things with PHP.

You still have a website still involves HTML, CSS, and JavaScript. A website will still send HTTP requests (and receive responses). The program will still need to be deployed so that it's reachable from the web. etc. etc. -- And there will always be adjacent things which you will either need (or benefit from) learning.

And there are many similarities of syntaxes between languages. For example javascript, php, C# and java all are c-like languages syntax wise.

The problem isn't on languages, it's on tooling. Docker, kubernetes, elasticsearch, git etc all have their own workflow and learning them isn't fast. Though with a solid basic programming, learning them is only a matter of time.
