What is the output of the code below ?

                        $now  = new DateTime();
$now2 = new DateTime();

$ago  = new DateInterval('P4Y10M3W');
$ago2 = new DateInterval('P4Y10M2W7D');

$then  = $now->sub($ago);
$date1 = $then->format('Y-m-d');

$then2 = $now2->sub($ago2);
$date2 = $then2->format('Y-m-d');

var_dump ($date1 === $date2);


                


                A)  bool(true) - because the two interval definitions are equivalent.                    
                    
                    
                                    

                B)  bool(false) - because the '2W' part in $ago2 will get overwritten by the '7D' part and therefor the second date interval will be 2 Weeks shorter than the first interval.                    
                    
                    
                                    

                C)  bool(false) and the script will throw a notice because the date/time interval notation in the $ago2 variable is wrong.                    
                    
                    
                                    

                D)  an error

                        Which of the following statements best describes the purpose of PHP's extract() function? This function accepts an array as its first argument.

                A)  An inherited member from a base class is overridden by a member inserted by a Trait, but members from the current class override Trait methods.

                C)  PHP is "single inheritance" so traits allow coders to reuse sets of methods from the trait freely in several independent classes
