How to Retrieve Dates within a Specified Range in PHP?

Obtaining Dates within a Specified Range

When presented with two specific dates, such as 20-4-2010 and 22-4-2010, a common programming task is to retrieve the intervening dates in a concise format, such as 20, 21, and 22. To achieve this, we can leverage various approaches in PHP.

Solution 1: Looping with strtotime and date

This involves using the strtotime() function to convert the dates to timestamps and then iterating through the range using a for loop. The date() function is used to format the timestamps as dates:

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

Solution 2: Looping with DateInterval and DateTime (PHP 5.3 )

PHP 5.3 and later offers a more concise and elegant solution using the DateInterval and DateTime classes:

<code class="php">$period = new DatePeriod(
    new DateTime('20-04-2010'),
    DateInterval::createFromDateString('+1 day'),
    new DateTime('23-04-2010')
);

foreach ($period as $dt) {
    echo $dt->format('d');
}</code>
