How to get month name of custom range - php

In my laravel application,
The input is like this:
$from_year = 2019;
$from_month = 10;
$to_year = 2020;
$to_month = 4;
The expected output:
months = [
'October 2019', 'November 2019', 'December 2019', 'January 2020', 'February 2020', 'March 2020', 'April 2020'
]
Thanks in advance.

You could use couple methods that uses DateTime. First of all, you could create current and end date (with 1st day of the month) objects, and then calculate month difference using date_diff. Then it's just simple for with adding month interval.
Vanilla PHP solution would look like this:
$from_year = 2019;
$from_month = 10;
$to_year = 2020;
$to_month = 4;
$date = new DateTime("$from_year-$from_month-01");
$diff = date_diff($date, new DateTime("$to_year-$to_month-01"));
$monthsDiff = $diff->y * 12 + $diff->m;
$interval = new DateInterval('P1M');
$monthsArray = [];
for($i = 0; $i <= $monthsDiff; $i++){
$monthsArray[] = $date->format('F Y');
$date->add($interval);
}
Also, as you can see, I'm using the format method on DateTime object. More about the method you can read here.

$startDate = date($from_year.'-'.$from_month.'-01');
$diff = (($to_year - $from_year) * 12) + ($to_month - $from_month);
$months = [];
for($i=0;$i<=$diff;$i++) {
$months[] = date('F Y', strtotime('+'.$i.' month', strtotime($startDate)));
}
simple code with date() function

try following code
<?php
$from_year = 2019;
$from_month = 10;
$to_year = 2020;
$to_month = 4;
$arr = [];
for($i=$from_year;$i<$to_year;$i++) {
if($i==$from_year){
$fmonth = $from_month;
}else{
$fmonth = 1;
}
for($j=$fmonth;$j<=12;$j++){
array_push($arr,DateTime::createFromFormat('!m', $j)->format('F'). " ".$i);
}
}
for($i=1;$i<=$to_month;$i++){
array_push($arr,DateTime::createFromFormat('!m', $i)->format('F'). " ".$to_year);
}
print_r($arr);
?>

This can be done using Carbon and CarbonPeriod libraries.
Here is how it goes:
use Carbon\Carbon;
use Carbon\CarbonPeriod;
$from_year = 2019;
$from_month = 10;
$to_year = 2020;
$to_month = 4;
$fromDate = new Carbon('1-' . $from_month . '-' . $from_year);
$toDate = new Carbon('1-' . $to_month . '-' . $to_year);
$differnces = CarbonPeriod::create($fromDate, '1 month', $toDate);
$differenceInDates = [];
foreach ($differnces as $differnce) {
$differenceInDates[] = $differnce->format("M F");
}
This will give you the result you want.

$from_year = 2019;
$from_month = 10;
$to_year = 2020;
$to_month = 4;
$start = strtotime($from_year . "-" . $from_month . "-01");
$end = strtotime($to_year . "-" . $to_month . "-01");
$months = [date("F Y",$start)];
while(strtotime(end($months)) < $end){
$months[] = date("F Y",strtotime(end($months) . " +1 month"));
}

Counting the (year)quarters between two dates

I have project built using laravel and a I have to build a function that counts all the complete quarters that are in the selected date range - the dates used are inserted via input.
Here are the quarters(i used numerical representations for the months)
01 - 03 first quarter
04 - 06 second quarter
07 - 09 third quarter
10 - 12 forth quarter
I would really appreciate your help,because I've been at it for an entire day now and basically have nothing to show for it,i thing I've been trying so hard i'm actually at the point where i'm so tired, i can t think straight.
I do have some code but it;s worthless, because it doesn't work, and any kind of idea or snippet of code is welcomed.
Thanks for your help in advance.
I managed to do this using multiple functions; basically, if this is needed for chart statistics, then a more specific approach might be the case.
I have done this in Laravel with timestamp dates as input (this code can be adapted for getting semesters also :) , it works and is already tested):
public static function getQuartersBetween($start_ts, $end_ts)
{
$quarters = [];
$months_per_year = [];
$years = self::getYearsBetween($start_ts, $end_ts);
$months = self::getMonthsBetween($start_ts, $end_ts);
foreach ($years as $year) {
foreach ($months as $month) {
if ($year->format('Y') == $month->format('Y')) {
$months_per_year[$year->format('Y')][] = $month;
}
}
}
foreach ($months_per_year as $year => $months) {
$january = new Date('01-01-' . $year);
$march = new Date('01-03-' . $year);
$april = new Date('01-04-' . $year);
$june = new Date('01-06-' . $year);
$july = new Date('01-07-' . $year);
$september = new Date('01-09-' . $year);
$october = new Date('01-10-' . $year);
$december = new Date('01-12-' . $year);
if (in_array($january, $months) && in_array($march, $months)) {
$quarter_per_year['label'] = 'T1 / ' . $year;
$quarter_per_year['start_day'] = $january->startOfMonth();
$quarter_per_year['end_day'] = $march->endOfMonth()->endOfDay();
array_push($quarters, $quarter_per_year);
}
if (in_array($april, $months) && in_array($june, $months)) {
$quarter_per_year['label'] = 'T2 / ' . $year;
$quarter_per_year['start_day'] = $april->startOfMonth();
$quarter_per_year['end_day'] = $june->endOfMonth()->endOfDay();
array_push($quarters, $quarter_per_year);
}
if (in_array($july, $months) && in_array($september, $months)) {
$quarter_per_year['label'] = 'T3 / ' . $year;
$quarter_per_year['start_day'] = $july->startOfMonth();
$quarter_per_year['end_day'] = $september->endOfMonth()->endOfDay();
array_push($quarters, $quarter_per_year);
}
if (in_array($october, $months) && in_array($december, $months)) {
$quarter_per_year['label'] = 'T4 / ' . $year;
$quarter_per_year['start_day'] = $october->startOfMonth();
$quarter_per_year['end_day'] = $december->endOfMonth()->endOfDay();
array_push($quarters, $quarter_per_year);
}
}
return $quarters;
}
and getting the years between:
public static function getYearsBetween($start_ts, $end_ts, $full_period = false)
{
$return_data = [];
$current = mktime(0, 0, 0, date('m', $start_ts), date('d', $start_ts), date('Y', $start_ts));
while ($current < $end_ts) {
$temp_date = $current;
$year = new Date($temp_date);
$return_data[] = $year;
$current = strtotime("+1 year", $current); // add a year
}
if ($full_period) {
$return_data[] = $end_ts;
}
return $return_data;
}
, also getting the months needed
public static function getMonthsBetween($start_ts, $end_ts, $full_period = false)
{
$return_data = $month_list = [];
$current = mktime(0, 0, 0, date('m', $start_ts), date('d', $start_ts), date('Y', $start_ts));
while ($current <= $end_ts) {
$temp_date = $current;
$date = new Date($temp_date);
$month_list[] = $date;
$current = strtotime("+1 month", $current); // add a month
}
$start_date_last_month = new Date(array_first($month_list));
$start_date_last_month = $start_date_last_month->startOfMonth()->format('m-d');
$temp_end_date = new Date($start_ts);
$temp_end_date = $temp_end_date->format('m-d');
if ($start_date_last_month < $temp_end_date) {
array_shift($month_list);
}
$end_date_last_month = new Date(end($month_list));
$current_day_month = $end_date_last_month->endOfMonth()->format('m-d');
$temp_end_date = new Date($end_ts);
$end_day_of_month = $temp_end_date->format('m-d');
if ($end_day_of_month < $current_day_month) {
array_pop($month_list);
}
if (count($month_list) == 0) {
$month_list[] = $end_date_last_month->subMonth();
}
$return_data = $month_list;
if ($full_period) {
$return_data[] = $end_ts;
}
return $return_data;
}
You can do something like in this example:
$February = 2;
$October = 10;
$completedQuarters = ceil($October/3) - ceil($February/3); // = 3
What about the quarter in which the date range starts, should it also count? If it should only count if it begins in the first month of a quarter you can check for it like this:
$completedQuarters = ceil($October/3) - ceil($February/3) -1; // = 2
if($February-1%3 == 0) $completedQuarters += 1;
You´re description is not very clear, let me know if that´s what you had in mind.
Not sure if the following is what you are meaning but might be useful
$date_start='2015/03/12';
$date_end='2017/11/14';
$timezone=new DateTimeZone('Europe/London');
$start=new DateTime( $date_start, $timezone );
$end=new DateTime( $date_end, $timezone );
$difference = $end->diff( $start );
$months = ( ( $difference->format('%y') * 12 ) + $difference->format('%m') );
$quarters = intval( $months / 3 );
printf( 'Quarters between %s and %s is %d covering %d months', $start->format('l, jS F Y'), $end->format('l, jS F Y'), $quarters, $months );
/*
This will output
----------------
Quarters between Thursday, 12th March 2015 and Tuesday, 14th November 2017 is 10 covering 32 months
*/
Something like this in the function and you should be set.
use Carbon\Carbon;
$first = Carbon::parse('2012-1-1'); //first param
$second = Carbon::parse('2014-9-15'); //second param
$fY = $first->year; //2012
$fQ = $first->quarter; //1
$sY = $second->year; //2014
$sQ = $second->quarter; //3
$n = 0; //the number of quarters we have counted
$i = 0; //an iterator we will use to determine if we are in the first year
for ($y=$fY; $y < $sY; $y++, $i++) { //for each year less than the second year (if any)
$s = ($i > 0) ? 1 : $fQ; //determine the starting quarter
for ($q=$s; $q <= 4; $q++) { //for each quarter
$n++; //count it
}
}
if ($sY > $fY) { //if both dates are not in the same year
$n = $n + $sQ; //total is the number of quarters we've counted plus the second quarter value
} else {
for ($q=$fQ; $q <= $sQ; $q++) { //for each quarter between the first quarter and second
$n++; //count it
}
}
print $n; //the value to return (11)

Calculate days in months between two dates with PHP

I have a period with startdate of 2016-12-26 and end date 2017-03-04.
Now I would like to find out how many days in each months there is, from a given period. Expected output from the above period dates (array):
2016-12: 5
2017-01: 31
2017-02: 28
2017-03: 4
How can I accomplish this cleanest way? I have tried to:
first looking at the period_start, get the days = 26 and
find out the start/end dates of the months between 2016-12 and 2017-03, to then calculate the days here (31 respectively 28 in february)
then finally calculating the 4 days in 2017-03.
But is there any cleaner/better way?
This can be achieved easily using the DateTime class. Create the objects, and use DateTime::diff() on them, then use the days property.
$start = new DateTime("2016-12-26");
$end = new DateTime("2017-03-04");
echo $start->diff($end)->days; // Output: 68

i used Carbon (https://carbon.nesbot.com/docs/) but you can do it with any other time lib.
$startDate = Carbon::createFromFormat('!Y-m-d', '2017-01-11');;
$endDate = Carbon::createFromFormat('!Y-m-d', '2018-11-13');;
$diffInMonths = $endDate->diffInMonths($startDate);
for ($i = 0; $i <= $diffInMonths; $i++) {
$start = $i == 0 ? $startDate->copy()->addMonth($i) : $startDate->copy()->addMonth($i)->firstOfMonth();
$end = $diffInMonths == $i ? $endDate->copy() : $start->copy()->endOfMonth();
echo $end->format('Y-m') . ' ' . ($end->diffInDays($start) + 1) . PHP_EOL;

Inserting dates within an array with PHP

I am getting the starting and ending dates from a form.
I need to put within an array all the date between the former two, including themselves.
I'm using a normal for loop and, at the same time, printing the result, to verify.
Everything appear to be alright.
But when I print_r the very array, I get only a series of equal dates. Which are all the same: last date + 1.
This is the code:
$date1 = date_create("2013-03-15");
$date2 = date_create("2013-03-22");
$diff = date_diff($date1, $date2);
echo $diff->format("%R%a days");
$diffDays = $diff->days;
echo $diffDays;
$dates = array();
$addDay = $date1;
for ($i = 0; $i < $diffDays; $i++) {
$dates[$i] = $addDay;
date_add($addDay, date_interval_create_from_date_string("1 day"));
echo "array: " . $i . " : " . date_format($dates[$i], 'Y-m-d');
}
print_r($dates);
PHP code demo
<?php
$dates = array();
$datetime1 = new DateTime("2013-03-15");
$datetime2 = new DateTime("2013-03-22");
$interval = $datetime1->diff($datetime2);
$days = (int) $interval->format('%R%a');
$currentTimestamp = $datetime1->getTimestamp();
$dates[] = date("Y-m-d H:i:s", $currentTimestamp);
for ($x = 0; $x < $days; $x++)
{
$currentTimestamp = strtotime("+1 day", $currentTimestamp);
$dates[] = date("Y-m-d H:i:s", $currentTimestamp);
}
print_r($dates);
I would do it that way
$startDate = new \DateTime("2017-03-15");
$endDate = new \DateTime("2017-03-22");
$dates = [];
$stop = false;
$date = $startDate;
while(!$stop){
$dates[] = $date->format('Y-m-d'); // or $dates[] = $date->format('Y-m-d H:i:s')
$date->modify('+1 day');
if($date->getTimestamp() > $endDate->getTimestamp()){
$stop = true;
}
}
print_r($dates);

PHP: List of days between two dates [duplicate]

This question already has answers here:
PHP: Return all dates between two dates in an array [duplicate]
(26 answers)
Closed 4 years ago.
Is there an easy way to get a list of days between two dates in PHP?
I would like to have something like this in the end:
(pseudocode)
date1 = 29/08/2013
date2 = 03/09/2013
resultArray = functionReturnDates(date1, date2);
and the resulting array would contain:
resultArray[0] = 29/08/2013
resultArray[1] = 30/08/2013
resultArray[2] = 31/08/2013
resultArray[3] = 01/09/2013
resultArray[4] = 02/09/2013
resultArray[5] = 03/09/2013
for example.
$date1 = '29/08/2013';
$date2 = '03/09/2013';
function returnDates($fromdate, $todate) {
$fromdate = \DateTime::createFromFormat('d/m/Y', $fromdate);
$todate = \DateTime::createFromFormat('d/m/Y', $todate);
return new \DatePeriod(
$fromdate,
new \DateInterval('P1D'),
$todate->modify('+1 day')
);
}
$datePeriod = returnDates($date1, $date2);
foreach($datePeriod as $date) {
echo $date->format('d/m/Y'), PHP_EOL;
}
function DatePeriod_start_end($begin,$end){
$begin = new DateTime($begin);
$end = new DateTime($end.' +1 day');
$daterange = new DatePeriod($begin, new DateInterval('P1D'), $end);
foreach($daterange as $date){
$dates[] = $date->format("Y-m-d");
}
return $dates;
}
dunno if this is at all practical, but it works pretty straight-forward
$end = '2013-08-29';
$start = '2013-08-25';
$datediff = strtotime($end) - strtotime($start);
$datediff = floor($datediff/(60*60*24));
for($i = 0; $i < $datediff + 1; $i++){
echo date("Y-m-d", strtotime($start . ' + ' . $i . 'day')) . "<br>";
}
Try this:
function daysBetween($start, $end)
$dates = array();
while($start <= $end)
{
array_push(
$dates,
date(
'dS M Y',
$start
)
);
$start += 86400;
}
return $dates;
}
$start = strtotime('2009-10-20');
$end = strtotime('2009-10-25');
var_dump(daysBetween($start,$end));
$datearray = array();
$date = $date1;
$days = ceil(abs($date2 - $date1) / 86400) + 1;//no of days
for($i = 1;$i <= $days; $i++){
array_push($datearray,$date);
$date = $date+86400;
}
foreach($datearray as $days){
echo date('Y-m-d, $days);
}

confusing date manipulations

tying to go through all sundays like this:
/*self::WEEK = 604800*/
/* 3600 * 24 * 7 looks like 7 days for me*/
$start = 1286053200;
for ($i=0; $i < 10; $i++) {
echo date('d.m.Y H:i:s.u, D (z)', $start) . ' (' . $start . ')<br/>';
$start += self::WEEK;
}
but in some case i see this:
03.10.2010 00:00:00.000000, Sun (275) (1286053200)
10.10.2010 00:00:00.000000, Sun (282) (1286658000)
17.10.2010 00:00:00.000000, Sun (289) (1287262800)
24.10.2010 00:00:00.000000, Sun (296) (1287867600)
31.10.2010 00:00:00.000000, Sun (303) (1288472400)
06.11.2010 23:00:00.000000, Sat (309) (1289077200) <--
13.11.2010 23:00:00.000000, Sat (316) (1289682000)
20.11.2010 23:00:00.000000, Sat (323) (1290286800)
27.11.2010 23:00:00.000000, Sat (330) (1290891600)
04.12.2010 23:00:00.000000, Sat (337) (1291496400)
in other words lost an hour!? where?!
Try strtotime()
$start = 1286053200;
for ($i=0; $i < 10; $i++) {
echo date('d.m.Y H:i:s.u, D (z)', strtotime(' +' . ($i * 7) . ' DAYS',$start)) . ' (' . $start . ')<br/>';
}
Daylight saving?
Try gmdate() instead.
I created a function for a similar problem. Maybe you'll find it useful.
function getDays($year, $dayofweek, $format, $timezone='UTC')
{
$fridays = array();
$startDate = new DateTime("{$year}-01-01 {$dayofweek}", new DateTimezone($timezone));
$year++;
$endDate = new DateTime("{$year}-01-01", new DateTimezone($timezone));
$int = new DateInterval('P7D');
foreach(new DatePeriod($startDate, $int, $endDate) as $d) {
$fridays[] = $d->format($format);
}
return $fridays;
}
$sundays = getDays('2010', 'Sunday', 'd.m.Y H:i:s.u, D (z)', 'America/New_York');
var_dump($sundays);
