Can PHP+PHPMyAdmin build large web?
I would like to ask you about how to build secure website. If I want to build some website that large scale (around 100,000 users use).

How do I manage about security? Only PHP and PHPMyAdmin is enough?

and tell me about the way that hacker could to attack my site. and how to protect?

Thanks!
