(Decentralized?) web hosting service supporting dynamic websites with little to no limitations?

Ok so this may sound naive or spoiled but I was thinking about creating a blog website with PHP and databases because I have used them before and I find them fun and easy to use. So what's a free option for creating dynamic websites (supporting at least PHP, CSS, and MySQL/any SQL) with the most permissive limitations on what content you can include (vulgarity, general crudeness, sexual language would end up in my blog at certain points)? I saw Cloudflare has the ToS I would want, but I seem to have gathered it only supports static sites, so no PHP and MySQL, is that right? I then came across this odd service called HelioHost, whose quality I'm unsure of. So then what avenues are there, +1 if they're decentralized options, that fit these criteria?
