Check if date is in specific date range PHP

Question

I'm trying this one out and it's been a while since I last coded in PHP.

I have a function that checks if given date is in between the range of dates:

pr($this->isDateBetween("2014-11-15", "2014-12-05", "2014-06-14"));

public function isDateBetween($dt_start, $dt_check, $dt_end){
        if(strtotime($dt_check) >= strtotime($dt_start) && strtotime($dt_check) <= strtotime($dt_end)){
            return true;
        } else{
            return false;
        }
    }

But seems like I'm getting false. The expected result should be true because 2014-12-05 is less than 2014-06-14 .

December is less than June so that should be true?

Also, When I change 2014-06-14 to 2014-12-14 it became true.

Sorry, I'm not updated anymore with PHP. Please bear with me.

Tried converting those to strtotime but still getting wrong results

You should probably find out which of the `dt_start` and `dt_end` is largest/smallest, then do an IF statement. The way you're doing it now, the order you've specified your arguments means no dates will be accepted. e.g. `2014-11-15` is your start date, but it is **after** `2015-06-14` which is your end date. — Jonathon, Dec 04 '14 at 17:18
Additionally, the middle parameter i.e. the date you are checking is outside of the range specified by the other parameters. — Jonathon, Dec 04 '14 at 17:23
Thanks I was confused. I need to study dates in a hard way but not thinking ahead — rukia_kuchiki_21, Dec 04 '14 at 17:24
you are misusing your method :) just swap the dt_start and dt_end — Hmmm, Dec 04 '14 at 17:26

The solution exist here:

How to check if a date is in a given range?

SOLUTION:

Converting them to timestamps is the way to go alright, using strtotime, e.g.

$start_date = '2009-06-17';

$end_date = '2009-09-05';

$date_from_user = '2009-08-28';

check_in_range($start_date, $end_date, $date_from_user);


function check_in_range($start_date, $end_date, $date_from_user)
{
  // Convert to timestamp
  $start_ts = strtotime($start_date);
  $end_ts = strtotime($end_date);
  $user_ts = strtotime($date_from_user);

  // Check that user date is between start & end
  return (($user_ts >= $start_ts) && ($user_ts <= $end_ts));
}

That's right. OP's question seems to be a duplicate of your linked post. — Choudhury Saadmaan Mahmid, Dec 04 '14 at 18:04

The expected result should be true because 2014-12-05 is less than 2014-06-14 .

Totally wrong. The code IS Working. June 14th is "less" than December 12th. So your Dec 12th date is NOT between the start/end dates. it's past the end of the range.

Absolutely not. The expected result is not true. It is false, because "2014-12-05" is not less than "2014-06-14". December less than June? Never heard of such a peculiar logic before.

Also, When I change 2014-06-14 to 2014-12-14 it became true.

That's right. Because "2014-12-05" is definitely less than "2014-12-14", it is true. 5 December is obviously smaller than 14 December.

This has nothing to do with PHP versions or PHP built-in methods. This is all about your logic.

I think this is what you're looking for:

pr($this->isDateBetween("2014-06-14", "2014-11-15", "2014-12-05"));

public function isDateBetween($dt_start, $dt_check, $dt_end){
        if(strtotime($dt_check) >= strtotime($dt_start) && strtotime($dt_check) <= strtotime($dt_end)){
            return true;
        } else{
            return false;
        }
}

This will return true.
