On the other, it has a bit of a reputation of being insecure.

Book review: Pro PHP Security by Chris Snyder and Michael Southwell

Good security is the basis of any viable website. With the internet being the most public of places, broken systems cost—money, reputations and possibly customer identities are the currency.

The book ranges from the almost theoretical to the highly practical such as SQL injection attack hardening and validating user input.
