DateTime: get next monday OR wednesday-CodePudding

Let's say I have a date and want to get the next monday OR wednesday, which was more closer from the date.

$date = 20211002;
$date_object = DateTime::createFromFormat('Ymd', $date);
$next = $date_object->modify('next wednesday')->format('d/m/Y');

Is possible to set two or more weekdays?

CodePudding user response：

No, but you can work around the issue:

// Closest "next" based on weekday ($date_object->format('w'))
// which is 0 (for Sunday) through 6 (for Saturday)
// 0 => monday    (from sunday)
// 1 => wednesday (from monday)
// 2 => wednesday (from tuesday)
// 3 => monday    (from wednesday)
// 4,5,6 => monday

So the next day is next wednesday only if format('w') is 1 or 2.

Therefore,

$go   = in_array(
    $date_object->format('w'),
    [ 1, 2 ]
) ? 'next wednesday' : 'next monday';
$next = $date_object->modify($go)->format('d/m/Y');
