I'm having the following array of dates :
Array
(
[0] => 2016-02-01

[4] => 2016-02-05
[5] => 2016-02-06
[6] => 2016-02-07
[7] => 2016-02-08
[8] => 2016-02-09
[9] => 2016-02-13
[10] => 2016-02-14
[11] => 2016-02-15
[12] => 2016-03-13
[13] => 2016-03-14
[14] => 2016-03-15
[15] => 2016-03-16
[16] => 2016-03-17
[17] => 2016-03-18
[18] => 2016-03-19
[19] => 2016-04-19
[20] => 2016-04-20
[21] => 2016-04-21
[22] => 2016-04-22
)
How can i get the array dates that form a range. Like
Array
(
[0] => 2016-02-01
[1] => 2016-02-02
[2] => 2016-02-03
[3] => 2016-02-04
[4] => 2016-02-05
[5] => 2016-02-06
[6] => 2016-02-07
[7] => 2016-02-08
[8] => 2016-02-09
)
Array
(
[0] => 2016-02-13
[1] => 2016-02-14
[2] => 2016-02-15
)
Array
(
[0] => 2016-03-13
[1] => 2016-03-14
[2] => 2016-03-15
[3] => 2016-03-16
[4] => 2016-03-17
[5] => 2016-03-18
[6] => 2016-03-19
)
The dates in the main array I listed can be of any order. The example I provided all the date ranges can be identifiable. But the raay is dynamic and can have date in random order. All I want to have date ranges out if that array. I'm getting mad of thinking. Please help. Thanks in advance.

You have the following code. Please try this.
$array = Array(0 => '2016-02-01',
1 => '2016-02-02',
2 => '2016-03-19',
3 => '2016-02-04',
4 => '2016-02-05',
5 => '2016-03-18',
6 => '2016-02-07',
7 => '2016-02-08',
8 => '2016-02-09',
9 => '2016-02-13',
10 => '2016-02-14',
11 => '2016-02-15',
12 => '2016-03-13',
13 => '2016-03-14',
14 => '2016-03-15',
15 => '2016-03-16',
16 => '2016-03-17',
17 => '2016-02-06',
18 => '2016-02-03',
19 => '2016-04-19',
20 => '2016-04-20',
21 => '2016-04-21',
22 => '2016-04-22');
//echo "<pre>";print_r($array);
sort($array);
$newDateArray = array();
$i = 0;
$arrayCount = count($array);
foreach($array as $key=>$val) {
//echo $key;
if(isset($array[$key+1])) {
$date1 = $val;
$date2 = $array[$key+1];
$newDateArray[$i][] = $date1;
$datetime1 = date_create($date1);
$datetime2 = date_create($date2);
$interval = date_diff($datetime1, $datetime2);
if($interval->days > 1) {
$i++;
}
}
else if($arrayCount == ($key+1)) {
$newDateArray[$i][] = $date2;
}
}
echo "<pre>";print_r($newDateArray);exit;
your result would be as follows.
Array
(
[0] => Array
(
[0] => 2016-02-01
[1] => 2016-02-02
[2] => 2016-02-03
[3] => 2016-02-04
[4] => 2016-02-05
[5] => 2016-02-06
[6] => 2016-02-07
[7] => 2016-02-08
[8] => 2016-02-09
)
[1] => Array
(
[0] => 2016-02-13
[1] => 2016-02-14
[2] => 2016-02-15
)
[2] => Array
(
[0] => 2016-03-13
[1] => 2016-03-14
[2] => 2016-03-15
[3] => 2016-03-16
[4] => 2016-03-17
[5] => 2016-03-18
[6] => 2016-03-19
)
[3] => Array
(
[0] => 2016-04-19
[1] => 2016-04-20
[2] => 2016-04-21
[3] => 2016-04-22
)
)
Now you can easily split your array. and get the result what you exactly want.
