I am trying to assign tomorrow date to a variable in my program call $tomorrow, but i just cant seem to work out how to do it. Have done today's one by doing

$date = date('Y-m-d');

after reseraching I thought it will make sense to do this

$tomorrow = mktime(0, 0, 0, date("m") , date("d")+1, date("Y"));
but this produced a long number (1141689600). making no sense.

I want the output to be as the same format as the date function used above.

Please please please please can someone help me. Thanks in advance

You saw a long number (1141689600) because that’s a Unix timestamp (seconds since 1970). The fix is to convert that timestamp into a formatted date instead of printing it raw. Several answers here used timestamps directly; below are clearer, more robust alternatives that avoid common pitfalls.

Simple, readable approach using a relative string with strtotime:

$tomorrow = date('Y-m-d', strtotime('+1 day'));

A more robust, timezone-aware method uses DateTime and DateInterval (preferred for production):

$dt = new DateTime('now', new DateTimeZone('America/New_York'));
$dt->add(new DateInterval('P1D'));
$tomorrow = $dt->format('Y-m-d');

You can also construct from the relative keyword in DateTime:

$tomorrow = (new DateTime('tomorrow', new DateTimeZone('UTC')))->format('Y-m-d');

Notes and caveats: , and were on the right track by generating a timestamp and formatting it, and ’s shell approach is fine for scripts run on Unix. Avoid simply adding 86400 seconds when incrementing a day — daylight saving transitions can make a day 23 or 25 hours. Also be aware of 32-bit timestamp limits on old systems; DateTime avoids that. Explicitly set the timezone (date_default_timezone_set or DateTimeZone) to prevent surprising results.

$tomorrow = date('Y-m-d',mktime(0,0,0,date('m'), date('d')+1, date('Y')));

Troy's code will work just fine, here's another way of doing it:

$tomorrow = date('Y-m-d',mktime()+86400);

Hi,

I think is better to use time() instead of mktime() in this case ;)

And a little explanation:

date() function get's two arguments. first one is date format, second one is function time() which get the current time in UNIX format.
We can manipulate time() function with - or + time.
so 86400 is the sum for the seconds in 24hours.
24*60*60 (24 hours * 60 mins * 60 sec).
Well date function will convert UNIX time time stamp to your date format. That's is...

excuse my english it's not my native language and i hope this will help you to understand how the things work out

TOMORROW=`expr \`date +%s\` + 86400`
date -r $TOMORROW
