To expand on previous answers  a function to do this could work like this  changing the time and interval formats however you like them according to this for function date  and this for DateInterval     I ve also written an alternate form of the below function here       Return adjusted time   function addMinutesToTime   time   plusMinutes           time   DateTime  createFromFormat   g i s    time         time- gt add  new DateInterval   PT       integer   plusMinutes      M            newTime    time- gt format   g i s          return  newTime      adjustedTime   addMinutesToTime   9 15 00   15     echo   lt h1 gt Adjusted Time       adjustedTime     lt  h1 gt     PHP EOL   PHP EOL

strtotime returns the current timestamp and date is to format timestamp       date strtotime date  h i sa    900   15 60 900 seconds    date date  h i sa   date     This will add 15 mins to the current time

Your code doesn t work  parse  because you have an extra   at the end that causes a Parse Error   Count  you have 2   and 3    It would work fine if you fix that  but strtotime   returns a timestamp  so to get a human readable time use date      selectedTime    9 15 00    endTime   strtotime   15 minutes   strtotime  selectedTime    echo date  h i s    endTime     Get an editor that will syntax highlight and show unmatched parentheses  braces  etc   To just do straight time without any TZ or DST and add 15 minutes  read zerkms comment      endTime   strtotime  selectedTime    900     900   15 min X 60 sec   Still  the   is the main issue here

Though you can do this through PHP s time functions  let me introduce you to PHP s DateTime class  which along with it s related classes  really should be in any PHP developer s toolkit      note this will set to today s current date since you are not specifying it in your passed parameter  This probably doesn t matter if you are just going to add time to it   datetime   DateTime  createFromFormat  g i s    selectedTime    datetime- gt modify   15 minutes    echo  datetime- gt format  g i s      Note that if what you are looking to do is basically provide a 12 or 24 hours clock functionality to which you can add subtract time and don t actually care about the date  so you want to eliminate possible problems around daylights saving times changes an such I would recommend one of the following formats    g i s 12-hour format without leading zeroes on hour   G i s 12-hour format with leading zeroes  Note the   item in format  This would set date component to first day in Linux epoch  1-1-1970
