I have trouble to increment time by 15 minutes to end time.
I tried date("H:i:s", strtotime('+15 minutes', strtotime($startTime)));.
But it is not dynamic.
Here i have starttime and endtime.
$startTime = '09:00:00';
$endTime = '11:00:00';
And want to output like,
09:00:00
09:15:00
09:30:00
09:45:00
10:00:00
10:15:00
10:30:00
10:45:00
Thanks.
Please try below code
$startTime='09:00:00';
$endTime='11:00:00';
$Times=array();
$interval=15;
while(strtotime($startTime) < strtotime($endTime))
{
$Times[]=$startTime;
$startTime=strtotime("+".$interval." minutes",strtotime($startTime));
$startTime=date('h:i:s',$startTime);
}
Output
Array
(
[0] => 09:00:00
[1] => 09:15:00
[2] => 09:30:00
[3] => 09:45:00
[4] => 10:00:00
[5] => 10:15:00
[6] => 10:30:00
[7] => 10:45:00
)
I think using do...while you can do this
use this code:
$startTime = '09:00:00';
$endTime = '11:00:00';
$inc = "";
do {
$inc = date("H:i:s", strtotime('+15 minutes', strtotime($startTime)));
$startTime = $inc;
echo $inc." ";
}while($inc < $endTime);
output:
09:15:00 09:30:00 09:45:00 10:00:00 10:15:00 10:30:00 10:45:00 11:00:00
You have to loop over time to generate data you want
$startTime = '09:00:00';
$endTime = '11:00:00';
$new_Time = $startTime;
while($new_Time < $endTime){
$new_Time = date("H:i:s", strtotime('+15 minutes', strtotime($new_Time)));
echo $new_Time;
echo "<br>";
}
o/p:
09:15:00
09:30:00
09:45:00
10:00:00
10:15:00
10:30:00
10:45:00
11:00:00
You can use following codes:
<?php
$startTime = '09:00:00';
$endTime = '11:00:00';
$times = array();
$last_inc = $startTime;
while($last_inc < $endTime) {
$times[] = $last_inc;
$last_inc = date("H:i:s", strtotime("+15 minutes $last_inc"));
}
print_r($times);
Ouput:
Array
(
[0] => 09:00:00
[1] => 09:15:00
[2] => 09:30:00
[3] => 09:45:00
[4] => 10:00:00
[5] => 10:15:00
[6] => 10:30:00
[7] => 10:45:00
)

I would like to get dates from tomorrow until 5 days with specify time and date values.
I tried this:
$date = date_create(date('d.m.Y 14:00:00'));
for ($x = 1; $x <= 5; $x++) {
date_add($date, date_interval_create_from_date_string("1 days"));
if ($date->format('w') >= 1 && $date->format('w') <= 5) {
$dates[] = date_format($date, "d.m.Y H:i:s");
}
for ($y = 0; $y < 4; $y++) {
if ($date->format('w') >= 1 && $date->format('w') < 5) {
if ($date->format('H') >= 16) {
$dates[] = date_format($date, "d.m.Y H:i:s");
}
} elseif ($date->format('w') == 5) {
$dates[] = date_format($date, "d.m.Y H:i:s");
}
date_add($date, date_interval_create_from_date_string("1 hours"));
}
date_add($date, date_interval_create_from_date_string("-4 hours"));
}
Result:
Array
(
[0] => 02.07.2021 14:00:00
[1] => 02.07.2021 14:00:00
[2] => 02.07.2021 15:00:00
[3] => 02.07.2021 16:00:00

[7] => 05.07.2021 17:00:00
[8] => 06.07.2021 14:00:00
[9] => 06.07.2021 16:00:00
[10] => 06.07.2021 17:00:00
)
But this is not correct.
It should be:
Array
(
[0] => 02.07.2021 14:00:00
[1] => 02.07.2021 15:00:00
[2] => 02.07.2021 16:00:00
[3] => 02.07.2021 17:00:00
[4] => 02.07.2021 18:00:00
[5] => 05.07.2021 16:00:00
[6] => 06.07.2021 17:00:00
[7] => 06.07.2021 18:00:00
)
Summary:
I would like to get all dates where the day ist NOT saturday or sunday with thime 16,17,18 o'clock. Is it es Friday additional 14 and 15 o'clock.
Where is my mistake ? :(
If you have PHP >= 5.1:
function isWeekend($date) {
return (date('N', strtotime($date)) >= 6);
}
function isWeekend($date) {
$weekDay = date('w', strtotime($date));
return ($weekDay == 0 || $weekDay == 6);
}
I am trying to write a program to dynamically add interval and find datetime between two dates in php.
I am getting Startdatetime, Enddatetime, Interval from the user.
If the
Start date is 2020-02-17 00:00:00, end date is 2020-02-17 08:00:00, and interval to be added to is 2hrs,
then I am trying to print all datetime ranges like
Array(
[0] => 2020-02-17 00:00:00
[1] => 2020-02-17 02:00:00
[2] => 2020-02-17 04:00:00
[3] => 2020-02-17 06:00:00
[4] => 2020-02-17 08:00:00
)
I tried with dateperiod, but doesn't work as it gives only start & end date
$period = new DatePeriod(
new DateTime($from_datetime),
new DateInterval('PT$hoursH'),
new DateTime($to_datetime)
);
Please help me to get all datetime ranges.
Using this:
<?php
$begin = new DateTime('2020-02-17 00:00:00');
$end = new DateTime('2020-02-17 08:00:01');
$interval = DateInterval::createFromDateString('2 hours');
$period = new DatePeriod($begin, $interval, $end);
$myDates = [];
foreach ($period as $dt) {
$myDates[] = $dt->format("Y-m-d H:i:s");
}
Now executing:
print_r($myDates);
gives you
Array (
[0] => 2020-02-17 00:00:00
[1] => 2020-02-17 02:00:00
[2] => 2020-02-17 04:00:00
[3] => 2020-02-17 06:00:00
[4] => 2020-02-17 08:00:00
)
You can use the date parser of PHP, its pretty intelligent.
$startDate = new DateTime('2020-02-17 00:00:00');
$endDate = new DateTime('2020-02-17 08:00:00');
$intervalInHrs = 2;
while ($startDate <= $endDate) {
$output[] = $startDate->format("Y-m-d H:i:s");
$startDate->modify("+$intervalInHrs Hours");
}
Output:
Array
(
[0] => 2020-02-17 00:00:00
[1] => 2020-02-17 02:00:00
[2] => 2020-02-17 04:00:00
[3] => 2020-02-17 06:00:00
[4] => 2020-02-17 08:00:00
)
$from_datetime = new DateTime('2020-02-17 00:00:00');
$to_datetime = new DateTime('2020-02-17 08:00:00');
$hours = 2;
$interval = new DateInterval('PT'.$hours.'H');
$period = new DatePeriod($from_datetime, $interval, $to_datetime);
$dateArray = [];
foreach ($period as $dt) {
$dateArray[] = $dt->format("Y-m-d H:i:s");
}
print_r($dateArray);exit;
Above code gave me the expected output as
Array
(
[0] => 2021-02-17 00:00:00
[1] => 2021-02-17 02:00:00
[2] => 2021-02-17 04:00:00
[3] => 2021-02-17 06:00:00
[4] => 2021-02-17 08:00:00

Hi i have the following date = 2015-06-01 00:00:00
so i have to add 3 month to this date , so write the following code
$sarting="2015-06-01 00:00:00";
$date[$i]=date('Y-m-d', strtotime($sarting . "+3 months") );
And i get the output = 2015-09-01;
But now i want to add 3 month again and again for 20 times and i have to store the output to array
so i write the following code
$store_date=array();
for($i=0;$i<20;$i++){
$store_date[$i]=date('Y-m-d', strtotime($sarting . "+3 months") );
}
But the thing it's returning 2015-09-01 20 times . i need like this 2015-09-01, 2015-12-01,2016-06-01 etc .
Please check
I would recommend using the DateTime-class so we can reuse the same instance on each iteration.
$sarting = "2015-06-01 00:00:00";
$store_date = [];
// Create a DateTime-object we can reuse
$date = new DateTime($sarting);
for ($i = 0; $i < 20; $i++) {
$date->modify('+3 months');
$store_date[] = $date->format('Y-m-d');
}
print_r($store_date);
Since we're resuing the same object, it will keep adding 3 months to it on each iteration. No need for any calculations or anything, making the code clean and readable.
Demo: https://3v4l.org/KZiH9
You can use PHP's dateTime class' modify() method to add +3 months in loop to it.
<?php
$dateStamp = "2015-06-01 00:00:00";
$date = new DateTime($dateStamp);
$datesArr = [];
for ($i=1; $i<21 ; $i++) {
$date->modify('+3 month');
$datesArr[] = $date->format('Y-m-d h:i:s');
}
echo '<pre>';
print_r($datesArr);
echo '</pre>';
Output:
Array

[0] => 2015-09-01 12:00:00
[1] => 2015-12-01 12:00:00
[2] => 2016-03-01 12:00:00
[3] => 2016-06-01 12:00:00

[19] => 2020-06-01 12:00:00
)
Working Code:
You are not changing the value of $sarting. Try this:
$sarting = "2015-06-01 00:00:00";
$store_date = array();
for ($i = 0; $i < 20; $i++) {
$sarting = $store_date[$i] = date('Y-m-d', strtotime($sarting . "+3 months"));
}
Try this check if it helps,
$sarting="2015-06-01 00:00:00";
$store_date=array();
for($i=0;$i<20;$i++){
$store_date[$i]=date('Y-m-d', strtotime($sarting . "+3 months") );
$sarting=$store_date[$i];
}
echo "<pre>";
print_r($store_date);
echo "</pre>";
Below code for Addition or Subtraction for Year/Month/day from date
Addition = date('Y-m-d', strtotime("+0 years +3 months +0 days", strtotime($lastdate)));
Subtraction = date('Y-m-d', strtotime("+0 years -3 months +0 days", strtotime($lastdate)));
$lastdate = "01-12-2015"; //actual date
$after_3_month = date('Y-m-d', strtotime("+0 years +3 months +0 days", strtotime($lastdate))); // adding 3 month on the actual date
echo $after_3_month; //3 month added with actual date
Good day everyone, I'm trying . This is the code which demonstrates what I'm doing:
<?php
$NoOfGames = 10;
$time = array("06:00:00 " => "07:00:00", "07:00:00" => "08:00:00", "08:00:00" => "09:00:00", "09:00:00" => "10:00:00", "10:00:00" => "11:00:00", "11:00:00" => "12:00:00","12:00:00" => "13:00:00","13:00:00" => "14:00:00","14:00:00" => "15:00:00","15:00:00" => "16:00:00","16:00:00" => "17:00:00","17:00:00" => "18:00:00");
for($i=0;$i<$NoOfGames;$i+1){
$start_time = array_rand($time);
$end_time = $time[$start_time];
$time_new[$start_time] = $end_time;
}
$i =1;
foreach($time_new as $start => $end)
{
echo $i. ") ". $start . " to ". $end . "<br>";
$i++;
}
?>
However, this outputs
and I want to display it like this instead
1) 17:00:00 to 18:00:00
2) 06:00:00 to 07:00:00
3) 12:00:00 to 13:00:00
4) 11:00:00 to 12:00:00
5) 16:00:00 to 17:00:00
6) 08:00:00 to 09:00:00
7) 13:00:00 to 14:00:00
8) 15:00:00 to 16:00:00
9) 14:00:00 to 15:00:00
10) 09:00:00 to 10:00:00
This should work:
Change $i+1 to $i++
The reason is that $i+1 just evaluates to 1 every time (ie doesn't actually increment $i), meaning the loop never exits.
I have a two dates. start date and end date. Using those dates i have to find recur dates.
example:
(1) start date = 2014-01-01
end date = 2014-05-01
expected output:
2014-01-01
2014-02-01
2014-03-01
2014-04-01
2014-05-01
(2) start date = 2014-01-31
end date = 2014-05-01
expected output:
2014-01-31
2014-02-28
2014-03-31
2014-04-30
means do not skip month, if month is skip in that case use last day of month. how to achive this thing?
I am using following code but i added 1 month in date so it skip the month:
$start = strtotime($start_date);
$end = strtotime($end_date);
$total_dates = array();
for($i=$start; $i<=$end;)
{
$date = date('Y-m-d',$start);
if($i>$start)
{
$next_date = date('Y-m-d',strtotime($date . "+1 month"));
$start = strtotime($next_date);
}
else
{
$next_date = date('Y-m-d',$start);
}
$total_dates[] = $next_date;
$date1 = new DateTime($date);
$newdate = date('Y-m-d',strtotime($date . "+1 month"));
$date2 = new DateTime($newdate);
$diff = $date2->diff($date1)->format("%a");
/* Find diff between two dates */
$i = (($i*1)+(86400*$diff)); //seconds in 1month
}
print_r($total_dates);
so in short:
start date = 2014-01-01
end date = 2014-05-01
expected output:
2014-01-31
2014-02-28
2014-03-31
2014-04-30
current output:
2014-01-31
2015-03-03
2015-04-03
check this
$start_date = '2015-01-31';
$end_date = '2016-06-01';
$start_date=date('Y-m-1', strtotime($start_date));
$diff = abs(strtotime($end_date) - strtotime($start_date));
$years = floor($diff / (365*60*60*24));
$months = floor(($diff - $years * 365*60*60*24) / (30*60*60*24));
if($years>0){$loop=$years*12+$months;}else{$loop=$months;}
for($i=1; $i<=$loop+1;$i++)
{
$total_dates[] =$a= date('Y-m-t', strtotime($start_date));
$start_date = date('Y-m-d',strtotime($start_date . "+1 month"));
}
print_r($total_dates);
//output Array ( [0] => 2015-01-31 [1] => 2015-02-28 [2] => 2015-03-31 [3] => 2015-04-30 [4] => 2015-05-31 [5] => 2015-06-30 [6] => 2015-07-31 [7] => 2015-08-31 [8] => 2015-09-30 [9] => 2015-10-31 [10] => 2015-11-30 [11] => 2015-12-31 [12] => 2016-01-31 [13] => 2016-02-29 [14] => 2016-03-31 [15] => 2016-04-30 [16] => 2016-05-31 [17] => 2016-06-30 )
Try this...
<?php
$start_date = "2014-01-01";
$end_date = "2014-05-01";
$d = date_parse_from_format("Y-m-d", $start_date);
$start= $d["month"];
$d1 = date_parse_from_format("Y-m-d", $end_date);
$end= $d1["month"];
$array=array();
$array[]=date('Y-m-t', strtotime($start_date));
for($i=$start;$i<$end;$i++)
{
$str=explode("-",$start_date);
$mon=$str[1]+$i;
$newdate=$str[0]."-".$mon."-".$str[2];
$array[]=date('Y-m-t', strtotime($newdate));
}
print_r($array);
output:

Use PHP date/time functions with relative interval formats:
http://php.net/manual/en/datetime.formats.relative.php
You can provide intervals like "last day of next month" or "last sat of July 2008", adding/subtracting this interval from the referenced date.
