Can't use method return value in write context

Question

I would think the following piece of code should work, but it doesn\'t (Edited: Now works in PHP 5.5+):

if (!empty($r->getError()))
         


        

Answer 1

I usually create a global function called is_empty() just to get around this issue

function is_empty($var)
{ 
 return empty($var);
}

Then anywhere I would normally have used empty() I just use is_empty()
