How to get day of the week in php?

If I've got a $date YYYY-mm-dd and want to get a specific $day (specified by 0 (sunday) to 6 (saturday)) of the week that YYYY-mm-dd is in.

For example, if I got 2012-10-11 as $date and 5 as $day, I want to get 2012-10-12, if I've got 0 as $day, 2012-10-14

EDIT:
Most of you misunderstood it. I got some date, $date and want to get a day specified by 0-6 of the same week $date is in.

So no, I don't want the day of $date...

I think this is what you want.

$dayofweek = date('w', strtotime($date));
$result    = date('Y-m-d', strtotime(($day - $dayofweek).' day', strtotime($date)));

You can use the date() function:

date('w'); // day of week

or

date('l'); // dayname

Example function to get the day nr.:

function getWeekday($date) {
    return date('w', strtotime($date));
}

echo getWeekday('2012-10-11'); // returns 4

Try

$date = '2012-10-11';
$day  = 1;
$days = array('Sunday', 'Monday', 'Tuesday', 'Wednesday','Thursday','Friday', 'Saturday');
echo date('Y-m-d', strtotime($days[$day], strtotime($date)));

If your date is already a DateTime or DateTimeImmutable you can use the format method.

$day_of_week = intval($date_time->format('w'));

The format string is identical to the one used by the date function.

To answer the intended question:

$date_time->modify($target_day_of_week - $day_of_week . ' days');

PHP Manual said :

w Numeric representation of the day of the week

You can therefore construct a date with mktime, and use in it date("w", $yourTime);

Just:

2012-10-11 as $date and 5 as $day

The $result = '2012-10-12' is what you want.

I'm afraid you have to do it manually. Get the date's current day of week, calculate the offset and add the offset to the date.

$current = date("w", $date)
$offset = $day - $current
$new_date = new DateTime($date)
    ->add(
        new DateInterval($offset."D")
    )->format('Y-m-d')
