[php] Get the date of next monday, tuesday, etc

if you want to find Monday then 'dayOfWeek' is 1 if it is Tuesday it will be 2 and so on.

var date=new Date();
getNextDayOfWeek(date, 2);

// this is for finding next tuesday

function getNextDayOfWeek(date, dayOfWeek) {
// Code to check that date and dayOfWeek are valid left as an exercise ;)

var resultDate = new Date(date.getTime());

resultDate.setDate(date.getDate() + (7 + dayOfWeek - date.getDay()) % 7);

return resultDate;
}

Hope this will be helpfull to you, thank you
