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

From the manual:

mixed end ( array &$array )

end takes the array by reference and move the internal pointer. Your array is the function output, so its unable to correctly modify the array by reference.
