PhpForeachDatePhp Problem Overview
I'm starting with a date 2010-05-01 and ending with 2010-05-10. How can I iterate through all of those dates in PHP?
Php Solutions
Solution 1 - Php
$begin = new DateTime('2010-05-01');
$end = new DateTime('2010-05-10');
$interval = DateInterval::createFromDateString('1 day');
$period = new DatePeriod($begin, $interval, $end);
foreach ($period as $dt) {
echo $dt->format("l Y-m-d H:i:s\n");
}
This will output all days in the defined period between $start and $end. If you want to include the 10th, set $end to 11th. You can adjust format to your liking. See the PHP Manual for DatePeriod. It requires PHP 5.3.
Solution 2 - Php
This also includes the last date
$begin = new DateTime( "2015-07-03" );
$end = new DateTime( "2015-07-09" );
for($i = $begin; $i <= $end; $i->modify('+1 day')){
echo $i->format("Y-m-d");
}
If you dont need the last date just remove = from the condition.
Solution 3 - Php
Converting to unix timestamps makes doing date math easier in php:
$startTime = strtotime( '2010-05-01 12:00' );
$endTime = strtotime( '2010-05-10 12:00' );
// Loop between timestamps, 24 hours at a time
for ( $i = $startTime; $i <= $endTime; $i = $i + 86400 ) {
$thisDate = date( 'Y-m-d', $i ); // 2010-05-01, 2010-05-02, etc
}
When using PHP with a timezone having DST, make sure to add a time that is not 23:00, 00:00 or 1:00 to protect against days skipping or repeating.
Solution 4 - Php
Copy from php.net sample for inclusive range:
$begin = new DateTime( '2012-08-01' );
$end = new DateTime( '2012-08-31' );
$end = $end->modify( '+1 day' );
$interval = new DateInterval('P1D');
$daterange = new DatePeriod($begin, $interval ,$end);
foreach($daterange as $date){
echo $date->format("Ymd") . "<br>";
}
Solution 5 - Php
Here is another simple implementation -
/**
* Date range
*
* @param $first
* @param $last
* @param string $step
* @param string $format
* @return array
*/
function dateRange( $first, $last, $step = '+1 day', $format = 'Y-m-d' ) {
$dates = [];
$current = strtotime( $first );
$last = strtotime( $last );
while( $current <= $last ) {
$dates[] = date( $format, $current );
$current = strtotime( $step, $current );
}
return $dates;
}
Example:
print_r( dateRange( '2010-07-26', '2010-08-05') );
Array (
[0] => 2010-07-26
[1] => 2010-07-27
[2] => 2010-07-28
[3] => 2010-07-29
[4] => 2010-07-30
[5] => 2010-07-31
[6] => 2010-08-01
[7] => 2010-08-02
[8] => 2010-08-03
[9] => 2010-08-04
[10] => 2010-08-05
)
Solution 6 - Php
$startTime = strtotime('2010-05-01');
$endTime = strtotime('2010-05-10');
// Loop between timestamps, 1 day at a time
$i = 1;
do {
$newTime = strtotime('+'.$i++.' days',$startTime);
echo $newTime;
} while ($newTime < $endTime);
or
$startTime = strtotime('2010-05-01');
$endTime = strtotime('2010-05-10');
// Loop between timestamps, 1 day at a time
do {
$startTime = strtotime('+1 day',$startTime);
echo $startTime;
} while ($startTime < $endTime);
Solution 7 - Php
User this function:-
function dateRange($first, $last, $step = '+1 day', $format = 'Y-m-d' ) {
$dates = array();
$current = strtotime($first);
$last = strtotime($last);
while( $current <= $last ) {
$dates[] = date($format, $current);
$current = strtotime($step, $current);
}
return $dates;
}
Usage / function call:-
Increase by one day:-
dateRange($start, $end); //increment is set to 1 day.
Increase by Month:-
dateRange($start, $end, "+1 month");//increase by one month
use third parameter if you like to set date format:-
dateRange($start, $end, "+1 month", "Y-m-d H:i:s");//increase by one month and format is mysql datetime
Solution 8 - Php
here's a way:
$date = new Carbon();
$dtStart = $date->startOfMonth();
$dtEnd = $dtStart->copy()->endOfMonth();
$weekendsInMoth = [];
while ($dtStart->diffInDays($dtEnd)) {
if($dtStart->isWeekend()) {
$weekendsInMoth[] = $dtStart->copy();
}
$dtStart->addDay();
}
The result of $weekendsInMoth is array of weekend days!

For Carbon users
use Carbon\Carbon;
$startDay = Carbon::parse("2021-08-01");
$endDay= Carbon::parse("2021-08-05");
$period = $startDay->range($endDay, 1, 'day');
When I print the data
[
Carbon\Carbon @1627790400 {#4970
date: 2021-08-01 00:00:00.0 America/Toronto (-04:00),
},
Carbon\Carbon @1627876800 {#4974
date: 2021-08-02 00:00:00.0 America/Toronto (-04:00),
},
Carbon\Carbon @1627963200 {#4978
date: 2021-08-03 00:00:00.0 America/Toronto (-04:00),
},
Carbon\Carbon @1628049600 {#5007
date: 2021-08-04 00:00:00.0 America/Toronto (-04:00),
},
Carbon\Carbon @1628136000 {#5009
date: 2021-08-05 00:00:00.0 America/Toronto (-04:00),
},
]
This is Laravel data dump using dd($period->toArray());. You can now iterate through $period if you want with a foreach statement.
One important note - it includes both the edge dates provided to method.
For more cool date related stuff, do check out the Carbon docs.
Solution 10 - Php
$date = new DateTime($_POST['date']);
$endDate = date_add(new DateTime($_POST['date']),date_interval_create_from_date_string("7 days"));
while ($date <= $endDate) {
print date_format($date,'d-m-Y')." AND END DATE IS : ".date_format($endDate,'d-m-Y')."\n";
date_add($date,date_interval_create_from_date_string("1 days"));
}
You can iterate like this also, The $_POST['date'] can be dent from your app or website
Instead of $_POST['date'] you can also place your string here "21-12-2019". Both will work.
Solution 11 - Php
<?php
$start_date = '2015-01-01';
$end_date = '2015-06-30';
while (strtotime($start_date) <= strtotime($end_date)) {
echo "$start_daten";
$start_date = date ("Y-m-d", strtotime("+1 days", strtotime($start_date)));
}
?>
Solution 12 - Php
If you use Laravel and want to use Carbon the correct solution would be the following:
$start_date = Carbon::createFromFormat('Y-m-d', '2020-01-01');
$end_date = Carbon::createFromFormat('Y-m-d', '2020-01-31');
$period = new CarbonPeriod($start_date, '1 day', $end_date);
foreach ($period as $dt) {
echo $dt->format("l Y-m-d H:i:s\n");
}
Remember to add:
- use Carbon\Carbon;
- use Carbon\CarbonPeriod;
