Adding 1 hour to time variable

Question

I have a time to which I want to add an hour:

$time = \'10:09\';

I\'ve tried:

$time = strtotime(\'+1 hour\');

strtotime(\'+1          


        

Answer 1

You can try this code:

$time = '10:09';

echo date( 'H:i', strtotime( '+1 hour' , strtotime($time) ) );

Answer 2

for this problem please follow bellow code:

$time= '10:09';
$new_time=date('H:i',strtotime($time.'+ 1 hour'));
echo $new_time;`
// now output will be: 11:09

Answer 3

You can use:

$time = strtotime("10:09") + 3600;
echo date('H:i', $time);

Or date_add: http://www.php.net/manual/en/datetime.add.php

Answer 4

$time = '10:09';
$timestamp = strtotime($time);
$timestamp_one_hour_later = $timestamp + 3600; // 3600 sec. = 1 hour

// Formats the timestamp to HH:MM => outputs 11:09.
echo strftime('%H:%M', $timestamp_one_hour_later);
// As crolpa suggested, you can also do
// echo date('H:i', $timestamp_one_hour_later);

Check PHP manual for strtotime(), strftime() and date() for details.

BTW, in your initial code, you need to add some quotes otherwise you will get PHP syntax errors:

$time = 10:09; // wrong syntax
$time = '10:09'; // syntax OK

$time = date(H:i, strtotime('+1 hour')); // wrong syntax
$time = date('H:i', strtotime('+1 hour')); // syntax OK

Answer 5

You can do like this

    echo date('Y-m-d H:i:s', strtotime('4 minute'));
    echo date('Y-m-d H:i:s', strtotime('6 hour'));
    echo date('Y-m-d H:i:s', strtotime('2 day'));

Answer 6

2020 Update

It is weird that no one has suggested the OOP way:

$date = new \DateTime(); //now
$date->add(new \DateInterval('PT3600S'));//add 3600s / 1 hour

OR

$date = new \DateTime(); //now
$date->add(new \DateInterval('PT60M'));//add 60 min / 1 hour

OR

$date = new \DateTime(); //now
$date->add(new \DateInterval('PT1H'));//add 1 hour

Extract it in string with format:

var_dump($date->format('Y-m-d H:i:s'));

I hope it helps
