Strict Standards php error

Question

I have a small issue with my script.

I\'m getting Strict Standards: Only variables should be passed by reference in

if( $checkDNS && ($domain = e         


        

Answer 1

Like the message says, end expects a variable because its parameter is a reference.

But since PHP 5.4 you can dereference arrays like that:

$domain = explode('@',$email, 2)[1];

Assuming that $email always contains @. You should assure that beforehand, otherwise end(...) would give you unexpected results too.
