What tools are better to use for parallel development in one php project?

Question

subversion

Hello.
Interested in the opinion of the community, what tools are better to use for parallel development in one php project? When googling on this topic, I come across options: SVN, GitHub, Mercurial (if something is not from this opera, please do not throw stones).
Actually, the question itself is what is better to use and why, based on your personal experience? There is no experience in setting up yet, but I think it's not a problem to figure it out.
Additional input data:
- There is only one server in the project;
- Need the ability to store versioned changes in the code;
- The used MySQL database weighs ~5gb (you need the ability to store versioning of the database), if it's Important.
And if it doesn’t make it difficult, please indicate in your recommendation what difficulties you may encounter.
Thanks in advance for your reply.

Answer 1

Git (GitHub) is a great choice as a version control system for code.
It also doesn’t hurt to use migrations, because changing the structure of the database will occur and synchronizing it manually is not the best solution.

Answer 2

We use a paid account on BitBucket and Git. Fine. You might as well pay to GitHub, but it's been getting DDed a lot lately.
