PHP convert the day date with the time - php

I am working on my php script to set up the date with the time. I need some help with convert the day date to the current day and next day date, example: my current time is 15:27 and my current date is 27-11-2019 so when I have the string for the variable get_time1 is 06:00:00, I want to convert it to 28-11-2019 06:00:00. When I have the variable get_time2 that have the time which it is 23:00:00 as my current time is before 23:00:00 so i want to convert the date with the current date with the time to 27-11-2019 23:00:00.
Code:
<?php
$get_time1 = '06:00:00';
$get_time2 = '23:00:00';
date_default_timezone_set('Europe/London');
$Date = date('Y-m-d');
$time = date('H:i:s');
?>
Can you please show me an example how I can set up the day date with the time 06:00:00 and 23:00:00 as if the time 06:00:00 is after 12am to set up the next day date and if the time 23:00:00 is before 12am then set up the time with the current date?
Thank you.

This just creates a DateTime object from the time (which will default it to todays date) and if this is less than the current date and time, it adds 1 day...
$date = DateTime::createFromFormat("H:i:s", $get_time2);
if ( $date < new DateTime() ) {
$date->modify("+1 day");
}
which gives
2019-11-27 23:00:00
and for $get_time1...
2019-11-28 06:00:00

If you use a DateTime that will allow you to do date arithmetic.
$now = new DateTime();
$tomorrow = $now->modify("+1 day");
You can also use strtotime to get a unix timestamp as explained in this answer.
$tomorrow = strtotime('+1 day');

maybe this will do?
$offset = timezone_offset_get( timezone_open( "Europe/London" ), new \DateTime() );
echo 'in London' . gmdate('d-m-Y H:i:s', date( "U" )+$offset);
echo 'current location: ' . date('d-m-Y H:i:s', date( "U" ));

converting UNIX time stamp date to the Monday of that week

how can i convert a time stamp to Monday corresponding with that week?
example:
1473750000 (Tue, 13 Sep 2016 07:00:00 GMT)
// coding magic
1473638400 (Mon, 12 Sep 2016 00:00:00 GMT )
To convert timestamps, you can use a PHP Function gmdate(). I already use this on some of my projects/sites.
$timestamp = strtotime("+1 hour"); //Uk Time
echo gmdate("H:i", $timestamp); //Hour:Minutes
For the other parts of gmdate(), check the PHP Manual.
I also add my solution to the problem, using DateInterval.
function getLastMonday($timestamp){
// Initialize DateTime object
$date = new DateTime();
$date->setTimestamp($timestamp);
// Calculate num of days to substract and create date interval
$dayOfWeek = $date->format("w");
$interval = new DateInterval("P".(($dayOfWeek+6)%7).'D');
$interval->invert = 1;
// Substract the Date interval
$date->add($interval);
return $date;
}
I've found an answer using the documentation provided in the answers:
$date = date('Y-m-d',strtotime('this monday this week',1473750000));

PHP strtotime returning always midnight

I'm having a weird problem. When I do strtotime it's not considering the hours part of the original date, and it's always returning midnight. I tried to research but I couldn't find anything specific.
Is there something I'm missing?
$original_date = "2015-08-07 02:00:00";
$next_date = date('Y-m-d H:i:s', strtotime("monday this Week +1 week", strtotime($original_date)));
It returns $next_date as 2015-08-14 00:00:00
Try this, add time which you want to retrieve in next date,.
$original_date = "2015-08-07 02:00:00";
echo $next_date = date('Y-m-d H:i:s', strtotime("monday this Week 02:00:00 +1 week", strtotime($original_date)));
monday this week +1 week assumes you’re looking for midnight of the monday of the week of the passed in time. If you want to preserve the hours part of the time, then you can append it to your date format because it should always be the same as in $original_date
date('Y-m-d ' . date('H:i:s', strtotime($original_date)), strtotime("monday this Week +1 week", strtotime($original_date)));
When you use monday in strtotime you're resetting the time back to 00:00:00. You will have to explicitly pass the time in either your date or strtotime to get your desired behavior. See this same question for a similar issue.
$next_date = date('Y-m-d H:i:s', strtotime("monday this Week +1 week " . date('H:i:s', strtotime($original_date)), strtotime($original_date)))
$date = strtotime('2018-08-14 02:00:00');
$next_date = date('Y-m-d H:i:s', strtotime("monday this Week 02:00:00 +1 week", $date)); // 2018-08-20 02:00:00

php add x weeks to a date and then find the next given day

I can add x week to my date
//$ultima_azione <--- 2015/07/15
//$data['intervallo'] <---- 5
$mydate = date("Y-m-d",strtotime($ultima_azione." +".$data['intervallo']." weeks"));
now how can i give a day starting from that week
example:
//$mydate + "next Monday" -----> final date
and this ve to work like, if today is Monday and i add weeks to jump to an other Monday and then i select the next Monday the week don't ve to change
The simplest way would be to use strtotime. It can do date calculations based on a textual representation of the delta:
$mydate = strtotime('+3 weeks');
It also accepts a second parameter, which is a timestamp to start from when doing the calculation, so after you get the offset in weeks, you can pass the new date to a second calculation:
// Get three weeks from 'now' (no explicit time given)
$mydate = strtotime('+3 weeks');
// Get the Monday after that.
$mydate = strtotime('next Monday', $mydate);
See strtotime documentation for more examples of notations that you can use.
I would highly recommend using PHP's built-in DateTime class for any date and time logic. It's a much better API than the older date and time functions and creates much cleaner and easier to read code.
For example:
// Current date and number of weeks to add
$date = '2015/07/15';
$weeks = 3;
// Create and modify the date.
$dateTime = DateTime::createFromFormat('Y/m/d', $date);
$dateTime->add(DateInterval::createFromDateString($weeks . ' weeks'));
$dateTime->modify('next monday');
// Output the new date.
echo $dateTime->format('Y-m-d');
References:
DateTime.
DateTime::createFromFormat
DateTime::add
DateTime::modify
DateInterval::createFromDateString
DateTime::format
Are you looking for something like this?
$today = time();
$weeks = 2;
// timestamp 2 weeks from now
$futureWeeks = strtotime("+ ".$weeks." weeks");
// the next monday after the timestamp date
$futureMonday = strtotime("next monday",$futureWeeks);
echo date("Y-m-d", $futureMonday);
// or in one line
echo date("Y-m-d", strtotime("next monday", strtotime("+ ".$weeks." weeks")));
PHP is using an unix timestamp for date calculations. Functions as date() and strtotime() using a timestamp as an optional second parameter. This is used a reference for formatting and calculations. If no timestamp is passed to the function the current timestamp is used (time()).
I have the answer here. This will show the next wednesday every 2 weeks and the first date to start from would be the 10th.
I have also added in an estimated delivery which would be 6 weeks after that date.
We will be placing our next order for this on:
<?php
$date = '2020/05/26';
$weeks = 2;
$dateTime = DateTime::createFromFormat('Y/m/d', $date);
$dateTime->add(DateInterval::createFromDateString($weeks . ' weeks'));
$dateTime->modify('wednesday');
echo $dateTime->format('d/m/Y');
?>
Expected delivery for the next order will be:
<?php
$date = '2020/05/26';
$weeks = 2;
$dateTime = DateTime::createFromFormat('Y/m/d', $date);
$dateTime->add(DateInterval::createFromDateString($weeks . ' weeks'));
$dateTime->modify('+42 days next wednesday');
echo $dateTime->format('d/m/Y');
?>
If anyone can confirm this is correct that would be great.

PHP, need to subtract 12 hours and 30 minutes from a DateTime

I have a PHP DateTime variable.
How can I reduce or subtract 12hours and 30 minutes from this date in at PHP runtime?
Subtract 12 Hours and 30 minutes from a DateTime in PHP:
$date = new DateTime();
$tosub = new DateInterval('PT12H30M');
$date->sub($tosub);
The P stands for Period. The T stands for Timespan.
See DateTime, DateTime::sub, and DateInterval in the PHP manual. You'll have to set the DateTime to the appropriate date and time, of course.
Try with:
$date = new DateTime('Sat, 30 Apr 2011 05:00:00 -0400');
echo $date->format('Y-m-d H:i:s') . "\n";
$date->sub(new DateInterval('PT12H30M'));
echo $date->format('Y-m-d H:i:s') . "\n";
//Result
2011-04-30 05:00:00
2011-04-29 16:30:00
Try strtotime() function:
$source_timestamp=strtotime("Sat, 30 Apr 2011 05:00:00 -0400");
$new_timestamp=strtotime("-12 hour 30 minute", $source_timestamp);
print date('r', $new_timestamp);
Maybe it will be useful for some cases
$date = new DateTime();
$date->modify('-12 hours -30 minutes');
echo $date->format('H:i:s');
try using this instead
//set timezone
date_default_timezone_set('GMT');
//set an date and time to work with
$start = '2014-06-01 14:00:00';
//display the converted time
echo date('Y-m-d H:i',strtotime('+1 hour +20 minutes',strtotime($start)));
If you are not so familiar with the spec of DateInterval like PT12H30M you can proceed with more human readable way using DateInterval::createFromDateString as follows :
$date = new DateTime();
$interval = DateInterval::createFromDateString('12 hour 30 minute');
$date->sub($interval);
Or with direct interval in sub function like below :
$date = new DateTime();
$date->sub(DateInterval::createFromDateString('12 hour 30 minute'));
Store it in a DateTime object and then use the DateTime::sub method to subtract the timespan.
I used in one line, for 12 hours only, and just as an hour display
$date = new DateTime(); $date->modify('-12 hours'); echo $date->format('H')-0;
I used the -0 since sometimes it put a 0 in front of the digit unless I done that, strange.
Here is detailed description of date function,
Using simply strtotime
echo date("Y-m-d H:i:s",strtotime("-12 hour -30 minutes"));
Using DateTime class
$date = new DateTime("-12 hour -30 minutes");
echo $date->format("Y-m-d H:i:s");

PHP one week ago from a specific date

so i have a date format like 07-09-10 and i want to know how to get ago from that date and if i can have a conditional like
if(is_date_with_1_week_of_above_date){
//do something
}
For checking date with relation to the Current Timestamp
if( strtotime( '-1 week' )>=$dateToCheck ) {
# $dateToCheck is within the last week
}
The other responses have good solutions for simple checking whether two date/times are within 1 week of each other - no point me repeating them.
Your date doesn't make clear the format (is it MM-DD-YY, DD-MM-YY, YY-MM-DD, etc.)? But an example using ISO 8601 date format is this:
$oneWeekAgo = strftime("%Y-%m-%d", strtotime("2010-07-09") - 60*60*24*7);
For a comparison, you can use the UNIX timestamp values
$date = "2010-07-09";
$compareDate = "2010-07-03";
$curTimestamp = strtotime($date);
$compareTimestamp = strtotime($compareDate);
if(abs($curTimestamp - $compareTimestamp) < 60*60*24*7)
{
// within 1 week
}
Edit
Per the comment on the date format, dd-mm-yy is a recognized format for dates, but mm-dd-yy is not in strtotime as seen here:
http://www.php.net/manual/en/datetime.formats.date.php
For it to work, you'd have to convert the dashes to slashes.
Also, if you're looking if the date is specifically one week prior,
$date = str_replace('-','/',"07-10-10");
$compareDate = str_replace('-','/',"07-03-10");
$curDate = strftime("%m/%d/%y", strtotime($date));
$compareDate = strftime("%m/%d/%y", strtotime($compareDate) + 60*60*24*7);
if($curDate == $compareDate)
{
// is one week prior
echo "OK";
}
Depending on your Time Zone, some days might have only 23 hours, so you can not use as a rule that a day has (60 seconds * 60 minutes * 24 hours) and with this, to calculate a specific date.
Specifying a date:
$specific_date = date( "Y-m-d" ); // for today
or
$specific_date = date( "Y-m-d", $timestamp ); // where timestamp is: Seconds since the Unix Epoch (January 1 1970 00:00:00 GMT)
The answer will be
$date = strtotime( $specific_date . " -1 week" );
