<code class="php">$start = strtotime('20-04-2010 10:00');
$end = strtotime('22-04-2010 10:00');
for ($current = $start; $current <= $end; $current += 86400) {
    echo date('d-m-Y', $current);
}

<code class="php">for ($i = 0; $i <= 2; $i++) {
    echo date('d-m-Y', strtotime("20-04-2010 +$i days"));
}

<code class="php">$period = new DatePeriod(
    new DateTime('20-04-2010'),
    DateInterval::createFromDateString('+1 day'),
    new DateTime('23-04-2010') // or pass in just the no of days: 2
);

foreach ( $period as $dt ) {
  echo $dt->format( 'd-m-Y' );
