Find missing dates in range (php)

Question

I would like to identify the missing dates in a PHP array

for example

this range

2013-06-12
2013-06-13
2013-06-26
2013-06-27
2013-06-29
         


        

Answer 1

Here's a good way to get all missing dates in an array:

format("Y-m-d");
  if(!in_array($formatted, $myDates)) $missingDates[] = $formatted;
}

print_r($missingDates);
?>

This will result in:

Array
(
    [0] => 2013-06-01
    [1] => 2013-06-02
    [2] => 2013-06-03
    [3] => 2013-06-04
    [4] => 2013-06-05
    [5] => 2013-06-06
    [6] => 2013-06-07
    [7] => 2013-06-08
    [8] => 2013-06-09
    [9] => 2013-06-10
    [10] => 2013-06-11
    [11] => 2013-06-14
    [12] => 2013-06-15
    [13] => 2013-06-16
    [14] => 2013-06-17
    [15] => 2013-06-18
    [16] => 2013-06-19
    [17] => 2013-06-20
    [18] => 2013-06-21
    [19] => 2013-06-22
    [20] => 2013-06-23
    [21] => 2013-06-24
    [22] => 2013-06-25
    [23] => 2013-06-28
    [24] => 2013-06-30
)
