Hi guys,
I wanted to create a website where people can register a profile, picture amongst other details. A networking site of sorts but for a niche that I don't think has been done before.
My question is, what kind of Programming language or software do I need to be proficient in for websites like these?
I'm kinda going about it the wrong way at the moment trying to look up HTML, Mysql, PHP etc all at once without focusing on a particular one. Baffling at the moment.
If anybody could point me in the right direction for the best tutorials as well i'd appreciate it. I've found a few on google but always worth seeing if there are better ones out there

That way I could read up on them when I have spare time at work.
Thank you all in advance, I appreciate it
Altoo
