Adding dates from SQL in PHP (types Datetime + Time) -

Adding dates from SQL in PHP (types Datetime + Time) -

i'd add together 2 values mysql database in php app. 1 stored datetime type, other 1 time.

$datetime; // "2013-02-08 14:00:00" $time; // "01:00:00"

i'd add together 1 hr $datetime, doesn't give me right result:

$newdatetime = strtotime($datetime) + strtotime($time); echo date('y-m-d h:i:s', $newdatetime); // "1920-02-11 08:31:44"

how can correctly?

$dt = new datetime("2013-02-08 14:00:00"); $dt->modify('+1 hour'); echo $dt->format('y-m-d h:i:s');

see in action
