empty() cannot check the return value of the method or function. which would 
be the best workaround?

empty($class->method())   // gets an error

i could do

$method_return_value = $class->method() and then run empty() on 
$method_return_value or is there an better option? i would like to do it in 
if statement....

i wrote an class for handling file uploads and there is an method 
getErrors() which returns empty array in case of 0 errors and i need to 
check it before i move any files. i'm just curious, what is the right way to 
do that!
