php Object of class DateInterval could not be converted to string

Question

i've tried using date_diff and date_create to get a difference from two date that's already converted to string.

here's the code:

$date_1 = date_create(); $date_now = date_format($date_1, 'Y-m-d');   //echo $date_now . "\n"; $date=date_create($date_now); date_add($date,date_interval_create_from_date_string("3 days")); $date_return =  date_format($date,"Y-m-d");   $diff = date_diff(date_create($date_now), date_create($date_return));  echo $diff; 

and i am getting this error:

Object of class DateInterval could not be converted to string 

Answer 1

You need to call DateInterval::format() to display that difference as a string.

echo $diff->format('%d days'); 

See the manual for all of the available formatting options.
