The entry level of programming industry is quite high. You can get a job without going to college to study php, but you can't get into a big company, because big companies need a college diploma or above.

However, the treatment of small companies is not bad, the salary is better than that of large companies, and other benefits may be worse.

You can go to school, but I suggest you take the adult college entrance examination to make up your diploma in the future, so as to avoid being brushed off because of diploma problems when you have the opportunity to enter the top of the company in the future.
