timestamp check if 10 minutes ago - php

I have a data in a text file saved using date("Y-m-d h:i:s", strtotime("+2 minutes")) that I need to check if it's 10 minutes ago. I'm trying the following code but it doesn't print anything even if more than 10 minutes ago.
$now = date("Y-m-d h:i:s", strtotime("now"));
if($now > strtotime($old_data))
echo 'expired!';

your comparing a formatted date with a time stamp which explains why nothing works
here:
$now = strtotime("-10 minutes");
if ($now > strtotime($old_data) {
echo 'expired!';
}

You should change either of the following:
$now = strtotime(date("Y-m-d h:i:s", strtotime("now")));
or
if (strtotime($now) > strtotime($old_data))
I'll go for the second. You are comparing a timestamp over date that is why you are not satisfying the condition of if().
Furthermore, you can also use time() if you're only concern is the current timestamp.
$now = time();
or
$now = date("Y-m-d h:i:s", strtotime("now")); // Remove this line
if(time() > strtotime($old_data)) // Change $now with time()

How to Display Current date+current time + 1 hour in text box in php [duplicate]

I currently have php returning the current date/time like so:
$now = date("Y-m-d H:m:s");
What I'd like to do is have a new variable $new_time equal $now + $hours, where $hours is a number of hours ranging from 24 to 800.
Any suggestions?
You may use something like the strtotime() function to add something to the current timestamp. $new_time = date("Y-m-d H:i:s", strtotime('+5 hours')).
If you need variables in the function, you must use double quotes then like strtotime("+{$hours} hours"), however better you use strtotime(sprintf("+%d hours", $hours)) then.
An other solution (object-oriented) is to use DateTime::add
Example:
<?php
$now = new DateTime(); //now
echo $now->format('Y-m-d H:i:s'); // 2021-09-11 01:01:55
$hours = 36; // hours amount (integer) you want to add
$modified = (clone $now)->add(new DateInterval("PT{$hours}H")); // use clone to avoid modification of $now object
echo "\n". $modified->format('Y-m-d H:i:s'); // 2021-09-12 13:01:55
Run script
DateTime::add PHP doc
DateInterval::construct PHP doc
You can use strtotime() to achieve this:
$new_time = date("Y-m-d H:i:s", strtotime('+3 hours', $now)); // $now + 3 hours
Correct
You can use strtotime() to achieve this:
$new_time = date("Y-m-d H:i:s", strtotime('+3 hours', strtotime($now))); // $now + 3 hours
You can also use the unix style time to calculate:
$newtime = time() + ($hours * 60 * 60); // hours; 60 mins; 60secs
echo 'Now: '. date('Y-m-d') ."\n";
echo 'Next Week: '. date('Y-m-d', $newtime) ."\n";
Um... your minutes should be corrected... 'i' is for minutes. Not months. :) (I had the same problem for something too.
$now = date("Y-m-d H:i:s");
$new_time = date("Y-m-d H:i:s", strtotime('+3 hours', $now)); // $now + 3 hours
I use this , its working cool.
//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)));
for add 2 hours to "now"
$date = new DateTime('now +2 hours');
or
$date = date("Y-m-d H:i:s", strtotime('+2 hours', $now)); // as above in example
or
$now = new DateTime();
$now->add(new DateInterval('PT2H')); // as above in example
You can try lib Ouzo goodies, and do this in fluent way:
echo Clock::now()->plusHours($hours)->format("Y-m-d H:m:s");
API's allow multiple operations.
For a given DateTime, you can add days, hours, minutes, etc. Here's some examples:
$now = new \DateTime();
$now->add(new DateInterval('PT24H')); // adds 24 hours
$now->add(new DateInterval('P2D')); // adds 2 days
PHP: DateTime::add - Manual https://www.php.net/manual/fr/datetime.add.php
$to = date('Y-m-d H:i:s'); //"2022-01-09 12:55:46"
$from = date("Y-m-d H:i:s", strtotime("$to -3 hours")); // 2022-01-09 09:55:46
$date_to_be-added="2018-04-11 10:04:46";
$added_date=date("Y-m-d H:i:s",strtotime('+24 hours', strtotime($date_to_be)));
A combination of date() and strtotime() functions will do the trick.
$now = date("Y-m-d H:i:s");
date("Y-m-d H:i:s", strtotime("+1 hours $now"));

How to change date format to strtotime in codeigniter

I want to convert date format to strtotime in codeigniter to cross check the expire date from the database.
My code look like this below
$expiredate = date("Y-m-d H:i:s", strtotime(date("Y-m-d H:i:s",strtotime($tra->t_started)). '+30days'));
if(strtotime(date("Y-m-d H:i:s")) > strtotime($expiredate)){
$ra->is_paid="1";
//package is expired for 30days.
} else{
$ra->is_paid="0";
//package is expired for 30days.
}
I need help to solve this problems. Thanks
Several issues here:
First, you don't need to convert dates with strtotime to compare them.
Second, to add a certain amount of days to a date, you use +30 day (singular) not +30 days
You could simply:
$now = date('Y-m-d H:i:s');
$expire_date = date('Y-m-d H:i:s', strtotime($tra->t_started."+30 day"));
if ($now >= $expire_date)
{
// 30 or more days overdue
}
else
{
// Less than 30 days overdue
}

Subtract minutes from date using strtotime

I have the current date format $date = 'yyyy-mm-dd hh:mm' and notice that $date is already set and not using the Date class. I understand I have to use strtotime which I have done to my $date $datestr = strtotime($date). I wish to subtract 5 minutes to the set time.
I've tried this simple thing $A = strtotime($date) - strtotime('-5 min'); But it does not aid me.
its simple to subtract the seconds of 5 minutes which is (5*60)=300 from your time
like this
$time = strtotime($date);
$time_new = $time-(5*60); // will time of the -5 min from the current $time
example
$date = date('d-M-Y g:i:s A'); // current date
echo $date."<br/>"; // output : 17-Feb-2014 8:35:58 AM
$time = strtotime($date); // convert current date to timestamp
$time_new = $time - (5*60); // subtract 5 minutes from current time.
$date_new = date('d-M-Y g:i:s A', $time_new); // convert time to the date again
echo $date_new; // output : 17-Feb-2014 8:30:58 AM

How to Subtract Minutes

I want to send a reminder email.I don't want to use cron on Linux/Unix/BSD box or Scheduled Tasks on Windows.
I'm trying to subtract 15 minutes from the current time.
here is my code so far (doesn't work):
$days = date("j",time());
$months = date("n",time());
$years = date("Y",time());
$hours = date("G",time());
$mins = (date("i",time()));
$secs = date("s",time());
$mins = $mins-15;
To subtract 15 minutes from the current time, you can use strtotime():
$newTime = strtotime('-15 minutes');
echo date('Y-m-d H:i:s', $newTime);
Change the date into a timestamp (in seconds) then minus 15 minutes (in seconds) and then convert back to a date:
$date = date("Y-m-d H:i:s");
$time = strtotime($date);
$time = $time - (15 * 60);
$date = date("Y-m-d H:i:s", $time);
You can use DateInterval
$date = new DateTime();
$interval = new DateInterval("PT15M");
$interval->invert = 1;
$date->add($interval);
echo $date->format("c") . "\n";
you can try this as well,
$dateTimeMinutesAgo = new DateTime("15 minutes ago");
$dateTimeMinutesAgo = $dateTimeMinutesAgo->format("Y-m-d H:i:s");
How about substracting the 15 minutes from time() before converting it?
$time = time() - (15 * 60);
And then use $time instead of time() in your code.
$currentTime = date('Y-m-d H:i:s');
$before15mins = strtotime('-15 minutes');
echo date('Y-m-d H:i:s', $before15mins);
You can also use strtotime function to subtract days, hours and/or seconds from current time.
echo date('Y-m-d H:i:s', strtotime('-15 minutes'));
Following is the way you can add days / hours / minutes / sec to current time
$addInterval = date('Y-m-d H:i:s', strtotime("+$days days $hours hours $minute minute $sec second", strtotime(currentTime)));
You can also use DateInterval object
<?php
$date = new DateTime('Y-m-d H:i:s');
$date->sub(new DateInterval('PT10H30S'));
echo $date->format('Y-m-d H:i:s');?>
Try using
$min = time() - 900; //900 seconds = 15 minutes
To subtract 15 minutes you can do:
date('Y-m-d H:i:s', (time() - 60 * 15));
You can replace 15 with the number of minutes you want.
In case you're looking to subtract seconds you can simply do:
date('Y-m-d H:i:s', (time() - 10));
In this way you'll subtract 10 seconds.
If you have only time value than below will be useful
// Your time
$time = '12:15:00';
// Returned value '12:00:00'
$newTime = date('H:i:s', strtotime($time) - (15*60));
I know this question is outdated but i just want to share how i did it in easy way
$current = new DateTime("10 minutes ago", new DateTimeZone('Asia/Manila') );
echo $current->format("Y-m-d H:i:s");
//To Get Current DateTime
$currentDate = date("Y-m-d H:i:s");
//To Get Current DateTime - 15Min
$oldDate = date("Y-m-d H:i:s", strtotime($currentDate) - (15 * 60));
echo $currentDate;
echo $oldDate;

Setting a time and date and adding to it in PHP

Basically am trying to set a time and a date in PHP then set a time gap which will range between minutes, loop through between a start time and end time echoing something out for each one. Have tried loads of different ways and cant seem to figure a way to set a date and add to it.
This seems the best script I have modified so far:
$minutes = 5;
$endtime = new DateTime('2012-01-01 09:00');
$newendtime = $endtime->format('Y-m-d H:i');
$timedate = new DateTime('2012-01-01 09:00');
while($stamp < $newendtime)
{
$time = new DateTime($timedate);
$time->add(new DateInterval('PT' . $minutes . 'M'));
$timedate = $time->format('Y-m-d H:i');
echo $timedate;
}
$minutes = 5;
$endtime = new DateTime('2012-01-01 09:00');
//modified the start value to get something _before_ the endtime:
$time = new DateTime('2012-01-01 8:00');
$interval = new DateInterval('PT' . $minutes . 'M');
while($time < $endtime){
$time->add($interval);
echo $time->format('Y-m-d H:i');
}
Do everything in seconds, and use php's time(), date(), and mktime functions.
In UNIX Time, dates are stored as the number of seconds since Jan 1, 1970.
You can render UNIX Timestamps with date().
$time = time(); // gets current time
$endtime = mktime(0,0,0, 1, 31, 2012); // set jan 31 # midnight as end time
$interval = 60 * 5; // 300 seconds = 5 minutes
while($time < $endtime){
$time += $interval;
echo date("M jS Y h:i:s a",$time) . "<br>"; // echos time as Jan 17th, 2012 1:04:56 pm
}
date reference:
http://us3.php.net/manual/en/function.date.php (includes superb date format reference too)
mktime reference: http://us2.php.net/mktime
time() only gets the current time, but just for kicks n' giggles: http://us2.php.net/time
And, it's super easy to store in a database!
This function will let you add date to your existing datetime. This will also preserves HH:MM:SS
<?php
function add_date($givendate,$day=0,$mth=0,$yr=0) {
$cd = strtotime($givendate);
$newdate = date('Y-m-d h:i:s', mktime(date('h',$cd),
date('i',$cd), date('s',$cd), date('m',$cd)+$mth,
date('d',$cd)+$day, date('Y',$cd)+$yr));
return $newdate;
}
?>
Usage:
add_date($date,12,0,0);
where $date is your date.
