In terms of employment opportunities, h5 is more than php (for example, if 10 company wants to recruit front-ends, there will be ten jobs in the front-end positions, but the back-ends recruited by this 10 company may not all recruit php, but it may be five Phps, three python and two java, so that php only has five jobs).

From the perspective of personal development, it is better to choose php, because php belongs to the back-end language. To learn the back end, you must learn the server database, and then you can develop into an architect or something. The cto of most companies is from the back end.

Personally, if you are not a computer major, choose the front end; if you are a computer major and are interested in programming, choose the back end (such as c/c++ java Python php golang).
