Laravel Carbon date diffInDays() on string error

Question

I need to find the difference between the two dates. Say i have 2017-02-01 - 2017-01-01. The number of days between the two days is the output

$formatted_d         


        

Answer 1

You can only use the diffInDays() function on a Carbon instance at before date format apply.

$formatted_dt1=Carbon::parse($a->date);
$formatted_dt2=Carbon::parse($c->dt);

Now you should be able to compare:

$date_diff=$formatted_dt1->diffInDays($formatted_dt2);

if you want to apply date format, try below for compare them:

$date_diff=$formatted_dt1->diffInDays($formatted_dt2)->format('Y-m-d');
