Get Date Range Of financial Year in php - php

Question

How can I get the Financial Year date range in PHP like below when I pass year and return date range of every year start and end.
Like Eg.
Input Array = [2017,2018]
Financial Start Month = 04
Output Array =
[
'2017' => [
'start' => '2016-04-01',
'end' => '2017-03-31'
],
'2018' => [
'start' => '2017-04-01',
'end' => '2018-03-31'
]
]
My Effort:-
$year_arr = [2017,2018];
$fn_month = 04;
$date_range_arr = [];
foreach ($year_arr as $key => $value) {
$fn_start_date_year = ($value - 1);
$fn_start_date_month = $fn_month;
$fn_start_date_day = '01';
$fn_start_date_string = $fn_start_date_year.'-'.$fn_start_date_month.'-'.$fn_start_date_day;
$start_date = date('Y-m-d',strtotime($fn_start_date_string));
$fn_end_date_year = ($value);
$fn_end_date_month = (fn_month == 1)?12:(fn_month-1);
$fn_end_date_day = date('t',strtotime($fn_end_date_year.'-'.$fn_end_date_month.'-01'));
$fn_start_date_string = $fn_end_date_year.'-'.$fn_end_date_month.'-'.$fn_end_date_day;
$end_date = date('Y-m-d',strtotime($fn_start_date_string));
$date_range_arr[$value] = [
'start_date' => $start_date,
'end_date' => $end_date
];
}
Above is my effort. It is working perfectly but needs a more robust code.

A good way to manipulate dates in PHP is using the DateTime class. Here's an example of how to get the results you want using it. By using the modify method, we can avoid worries about complications like leap years (see the result for 2016 below).
$year_arr = [2016,2017,2018];
$fn_month = 03;
foreach ($year_arr as $year) {
$end_date = new DateTime($year . '-' . $fn_month . '-01');
$start_date = clone $end_date;
$start_date->modify('-1 year');
$end_date->modify('-1 day');
$date_range_arr[$year] = array('start_date' => $start_date->format('Y-m-d'),
'end_date' => $end_date->format('Y-m-d'));
}
print_r($date_range_arr);
Output:
Array (
[2016] => Array (
[start_date] => 2015-03-01
[end_date] => 2016-02-29
)
[2017] => Array (
[start_date] => 2016-03-01
[end_date] => 2017-02-28
)
[2018] => Array (
[start_date] => 2017-03-01
[end_date] => 2018-02-28
)
)

Maybe this is what you need?
I use strtotime to parse the date strings.
$year_arr = [2017,2018];
$fn_month = 04;
$date_range_arr = [];
foreach($year_arr as $year){
$date_range_arr[$year] =['start' => date("Y-m-d", strtotime($year-1 . "-" .$fn_month . "-01")),
'end' => date("Y-m-d", strtotime($year . "-" .$fn_month . "-01 - 1 day"))];
}
var_dump($date_range_arr);
Output:
array(2) {
[2017]=>
array(2) {
["start"]=>
string(10) "2016-04-01"
["end"]=>
string(10) "2017-03-31"
}
[2018]=>
array(2) {
["start"]=>
string(10) "2017-04-01"
["end"]=>
string(10) "2018-03-31"
}
}

Try this snippet,
function pr($a)
{
echo "<pre>";
print_r($a);
echo "</pre>";
}
$year_arr = [2017, 2018];
$fn_month = 4;
$date_range_arr = [];
foreach ($year_arr as $key => $value) {
$fn_month = str_pad(intval($fn_month),2, 0, STR_PAD_LEFT);
$date = "".($value-1)."-$fn_month-01"; // first day of month
$date_range_arr[$value] = [
'start_date' => $date,
'end_date' => date("Y-m-t", strtotime($date.' 11 months')), // last month minus and last date of month
];
}
pr($date_range_arr);
die;
str_pad - Pad a string to a certain length with another string
Here is working demo.
