How to get all dates between two dates in PHP?

Hello Developers! In this post, I will show you, How to get all dates between two dates in PHP. This article goes into detail on how to get all dates between two dates in PHP with a few lines of code. I will give you Two simple and easy examples with solutions. So let's start to get dates between two dates.

Example 1: Get all dates between two dates with strtotime function

In the first example, we will use strtotime() function to get all dates between two dates.

Note: 

• The strtotime() function is a built-in function in PHP that is used to convert an English textual date-time description to a UNIX timestamp.
• There are 86,400 seconds in 1 day, So, I have use 86400 in for loop.

<?php
    function getAllDates($startingDate, $endingDate)
    {
        $datesArray = [];

        $startingDate = strtotime($startingDate);
        $endingDate = strtotime($endingDate);
             
        for ($currentDate = $startingDate; $currentDate <= $endingDate; $currentDate += (86400)) {
            $date = date('Y-m-d', $currentDate);
            $datesArray[] = $date;
        }
  
        return $datesArray;
    }
  
    $dates = getAllDates('2021-01-01', '2021-01-10');
     
    print_r($dates);
  
?>

Output:

Array (
     [0] => 2021-01-01 
     [1] => 2021-01-02 
     [2] => 2021-01-03 
     [3] => 2021-01-04 
     [4] => 2021-01-05 
     [5] => 2021-01-06 
     [6] => 2021-01-07 
     [7] => 2021-01-08 
     [8] => 2021-01-09 
     [9] => 2021-01-10
)

Example 2: Get all dates with DateInterval function

In the second example, We will use another PHP function called by DateInterval().

Note: 

• A date interval stores either a fixed amount of time (in years, months, days, hours etc) or a relative time string in the format that DateTime's constructor supports. More specifically, the information in an object of the DateInterval class is an instruction to get from one date/time to another date/time. you can visit php.net for more information about this function.
• This function will not show last date e.g If we wanna get dates from 1 to 10, It will show all dates from 1 to 9 not will show the last date.

<?php
    $datesArray = []; 
    $timePeriod = new DatePeriod(
        new DateTime('2021-01-01'),
        new DateInterval('P1D'),
        new DateTime('2021-01-10')
    );

    foreach ($timePeriod as $key => $value) {
        $date = $value->format('Y-m-d');    
        $datesArray[] = $date;  
    }

    print_r($datesArray);
?>

Output:

Array (
     [0] => 2021-01-01 
     [1] => 2021-01-02 
     [2] => 2021-01-03 
     [3] => 2021-01-04 
     [4] => 2021-01-05 
     [5] => 2021-01-06 
     [6] => 2021-01-07 
     [7] => 2021-01-08 
     [8] => 2021-01-09 
)

I hope it can be helpful for you.

Happy Coding :)
