127.0.0.1.1 is considered a valid domain by this function.

This code example is bad and should not be used! It is a genuent security risk!

Shit like this returns a valid result:
filter_var_domain(‘www.137.com?”(OR(1=1))’)

@Felipe Braz’s solution is not as insecure as the Posters.

Blog posts and “solutions” are the reason PHP get a bad rep. So please remove this post so less experienced coders don’t use this in their application.

I’m using: filter_var(‘admin@’.$domain, FILTER_VALIDATE_EMAIL); =)
