Yield each date in a [start, end] interval as a DateTimeImmutable, with a configurable step. Builds on DatePeriod under the hood — but exposes a generator so you can break out early.
PHP
<?php
function dateRange(DateTimeInterface $start, DateTimeInterface $end, string $step = 'P1D'): Generator {
$cursor = DateTimeImmutable::createFromInterface($start);
$endImm = DateTimeImmutable::createFromInterface($end);
$stepIv = new DateInterval($step);
while ($cursor <= $endImm) {
yield $cursor;
$cursor = $cursor->add($stepIv);
}
}
foreach (dateRange(new DateTime('2025-01-01'), new DateTime('2025-01-05')) as $d) {
echo $d->format('Y-m-d'), PHP_EOL;
