It's fine to start out with anything, I did pascal/visual basic in high school. Then did Java/PHP in college. First year of college I did contract work in PHP and in WordPress. It was fun the first year or so and I love that I could have that "instant gratification" moments that PHP is famous for. Then as I grew and learned about things like concurrency, algorithms, HTTP, networking I found myself wondering off to other languages such as Ruby. Then I learned Ruby and now for a year already am doing Rails and Angular and truly enjoy it.
The thing to note here is back in a day when I was doing PHP , I heard a lot from community members and other software engineers saying something like "PHP SUCKS" and stuff like that, but I did not care because everything I wanted to build in that time I could do with procedural PHP or some OOP php or some Wordpress magic. When I realized and knew `why` I want to learn other stuff everything became clear.
