Holy macaroni. Talk about overkill!
if (substr($mydata->restored,0,4) == "0000") { }
Or in your very specific case you could do the harder way and note that
strings work like simple arrays too in a way, so $mydata->restored{0}
through $mydata->restored{3} should all be '0' ( note the {} and not [] ).
You can use a forloop or just manually check them all with && or || or
whatever logic you feel comfortable with. But the substr is by far the
simplest.
