Splitting dates - php

Question

$one = array('start' => '2012-10-12', 'stop' => '2012-11-04', 'over' => false);
$two = array('start' => '2012-10-29', 'stop' => '2012-11-14', 'over' => true);
$three = array('start' => '2012-11-12', 'stop' => '2012-12-07', 'over' => false);
$array = array($one, $two, $three);
this show me:
Array
(
[0] => Array
(
[start] => 2012-10-12
[stop] => 2012-11-04
[over] =>
)
[1] => Array
(
[start] => 2012-10-29
[stop] => 2012-11-14
[over] => 1
)
[2] => Array
(
[start] => 2012-11-12
[stop] => 2012-12-07
[over] =>
)
)
I would like make function for splitting these dates.
If in array is over = true then this date should split other dates.
For this example this should return:
Array
(
[0] => Array //this is changed
(
[start] => 2012-10-12
[stop] => 2012-10-28
[over] =>
)
[1] => Array //this is ok
(
[start] => 2012-10-29
[stop] => 2012-11-14
[over] => 1
)
[2] => Array //this is changed
(
[start] => 2012-11-15
[stop] => 2012-12-07
[over] =>
)
)
And second example:
$one = array('start' => '2012-10-12', 'stop' => '2012-12-04', 'over' => false);
$two = array('start' => '2012-10-29', 'stop' => '2012-11-14', 'over' => true);
$second = array($one, $two);
this return me:
Array
(
[0] => Array
(
[start] => 2012-10-12
[stop] => 2012-12-04
[over] =>
)
[1] => Array
(
[start] => 2012-10-29
[stop] => 2012-11-14
[over] => 1
)
)
and i would like receive:
Array
(
[0] => Array //this is changed - old [0] date
(
[start] => 2012-10-12
[stop] => 2012-10-28
[over] =>
)
[1] => Array //this is ok
(
[start] => 2012-10-29
[stop] => 2012-11-14
[over] => 1
)
[2] => Array //this is new - from old [0] date - next part
(
[start] => 2012-11-15
[stop] => 2012-12-04
[over] =>
)
)

How can I do it with PHP?

Answer 1

Try this.
foreach($arr as $key=>$val)
{
if(isset($arr[$key+1]) && $arr[$key+1]['over'] == true)
$arr[$key]['stop'] = date('Y-m-d', strtotime($arr[$key+1]['start'] .' -1 day'));
if(isset($arr[$key-1]) && $arr[$key-1]['over'] == true)
$arr[$key]['start'] = date('Y-m-d', strtotime($arr[$key-1]['stop'] .' +1 day'));
}
you can find the code here.
Update:
$arr1 = $arr;
foreach($arr as $key=>$val)
{
if(isset($arr[$key+1]) && $arr[$key+1]['over'] == true)
{
$arr[$key]['stop'] = date('Y-m-d', strtotime($arr[$key+1]['start'] .' -1 day'));
$arr[$key]['over'] = true;
}
if(isset($arr[$key-1]) && $arr[$key-1]['over'] == true)
{
$arr[$key]['start'] = date('Y-m-d', strtotime($arr[$key-1]['stop'] .' +1 day'));
$arr[$key]['over'] = true;
}
}
foreach($arr1 as $key=>$val)
{
$arr[$key]['over'] = $arr1[$key]['over'];
}
