I think this is similar to kouton's answer, but this one just takes in a timeStamp and returns a timestamp SOMEWHERE in the next month. You could use date("m", $nextMonthDateN) from there.

function nextMonthTimeStamp($curDateN){ 
   $nextMonthDateN = $curDateN;
   while( date("m", $nextMonthDateN) == date("m", $curDateN) ){
      $nextMonthDateN += 60*60*24*27;
   }
   return $nextMonthDateN; //or return date("m", $nextMonthDateN);
}
