How to check if a date is today or yesterday

Using Carbon:

$date = Carbon::parse($dt);

$isToday = $date->isToday();

$isYesterday = $date->isYesterday();

$isTodayOrYesterday =  $date->isToday() || $date->isYesterday();

I am passing a datetime like this "2019-10-02 09:21:52"

Your answer keeps returning false on both queries

What is the application's timezone, and how does that relate to your timezone?

Also, what is your server's system time?

Here is my tinker test, and it works perfectly well:

>>> Carbon\Carbon::parse("2019-10-02 09:21:52")
=> Carbon\Carbon @1570008112 {#3031
     date: 2019-10-02 09:21:52.0 UTC (+00:00),
   }
>>> $date = Carbon\Carbon::parse("2019-10-02 09:21:52")
=> Carbon\Carbon @1570008112 {#3034
     date: 2019-10-02 09:21:52.0 UTC (+00:00),
   }
>>> $date->isToday()
=> true
>>> $date->isYesterday()
=> false
>>> 

Can you show your code? I just did this and got 1 (true)

    $date = Carbon::parse("2019-10-02 09:21:52");

    return $date->isToday() ? 1 : 0;

If your server's system time is incorrect/different timezone, you will be testing against that time, rather than your real local time.

You can try using now(); to see the current system time.

Thanks alot guys, i appreciate you all...

It was working alright.... I was passing the wrong time in my controller...
