too long

Question

I was wondering if it is possible to use PHP to figure out when a specific date it.

For example:

// Next week
$date->setDate(2014, 4, 3);

if($date->format('Y-m-d') == NEXT_WEEK){
// Do something
}elseif($date->format('Y-m-d') == NEXT_MONTH){
// DO something else
}elseif($date->format('Y-m-d') == NEXT_YEAR){
// Do something else
}

I understand my code won't work, but I am looking for something that would achieve something similar to that?

Answer 1

This can be achieved with DateTime objects using diff to see the time in between, something like this should do the trick:

// The date we want to check
$checkDate = new DateTime('2014-04-03', new DateTimeZone('UTC'));
// We need to compare it against today + a specific interval,
// so create a seperate DateTime object for today
$today = new DateTime('now', new DateTimeZone('UTC'));

// Check the difference between the dates
$diff = $today->diff($checkDate);

if ($diff->y == 0 && $diff->m == 0 && $diff->d == 7) {
    // Date lies a week in the future
} elseif ($diff->y == 0 && $diff->m == 1 && $diff->d == 0) {
    // Date lies a month in the future
} elseif ($diff->y == 1 && $diff->m == 0 && $diff->d == 0) {
    // Date lies a year in the future
}
