PHP 5.3.x的安全性是否低于PHP 5.6.x

Question

Does the version of PHP effect the security of my website?

This article , among others, points to a mild & vague 'yes.'

Answer 1

The mild & vague answer comes from a mild & vague question. You need to create a question that expects an answer that is not limited to "yes" or "no".

Your question "Does the version of PHP effect the security of my website?" can only accept two answers: "yes" or "no".

So, Yes , it affects the security. (may be positive, or negative, but affects)

If you ask, instead: "What are the security differences between two PHP versions?" then this question will not accept "yes" or "no", and will need an more detailed explanation, that, I think, its what you're looking for.
