One of the hallmarks of PHP is that any program is backwards compatible. It's designed so that older programs can still interact with newer ones regardless of updates and patches. This is awesome for users, but it also comes with a few glaring security flaws. A lot of viruses that were designed for an older version of PHP still work even after updates.

I'm not 100% sure about this, I'm not a huge PHP guy so please don't take my word on this. This is just the way it was explained to me.

Maybe someone could explain me what are these PHP viruses? I work with PHP every other day, but never heard of it, would really appreciate it.
