If you want to do this in PHP      replace time   with the time stamp you want to add one day to  startDate   time    date  Y-m-d H i s   strtotime   1 day    startDate      If you want to add the date in MySQL   -- replace CURRENT DATE with the date you want to add one day to SELECT DATE ADD CURRENT DATE  INTERVAL 1 DAY

There s more then one way to do this with DateTime which was introduced in PHP 5 2  Unlike using strtotime   this will account for daylight savings time and leap year    datetime   new DateTime  2013-01-29     datetime- gt modify   1 day    echo  datetime- gt format  Y-m-d H i s        Available in PHP 5 3   datetime   new DateTime  2013-01-29     datetime- gt add new DateInterval  P1D     echo  datetime- gt format  Y-m-d H i s        Available in PHP 5 4  echo  new DateTime  2013-01-29   - gt add new DateInterval  P1D   - gt format  Y-m-d H i s        Available in PHP 5 5   start   new DateTimeImmutable  2013-01-29     datetime    start- gt modify   1 day    echo  datetime- gt format  Y-m-d H i s

There is a more concise and intuitive way to add days to php date  Don t get me wrong  those php expressions are great  but you always have to google how to treat them  I miss auto-completion facility for that   Here is how I like to handle those cases    new Future      new DateTimeFromISO8601String  2014-11-21T06 04 31 321987 00 00        new OneDay          - gt value      For me  it s way more intuitive and autocompletion works out of the box  No need to google for the solution each time   As a nice bonus  you don t have to worry about formatting the resulting value  it s already is ISO8601 format   This is meringue library  there are more examples here

The DateTime constructor takes a parameter string time   time can be different things  it has to respect the datetime format   There are some valid values as examples      now   the default value  2017-10-19 2017-10-19 11 59 59 2017-10-19  1day   So  in your case you can use the following    dt   new  DateTime  now  1 day      Tomorrow  dt   new  DateTime  2016-01-01  1 day      2016-01-02

Use strtotime to convert the string to a time stamp Add a day to it  eg  by adding 86400 seconds  24   60   60     eg    time   strtotime  myInput    newTime    time   86400    If it s only adding 1 day  then using strtotime again is probably overkill
