EXAMPLES
Example #1
DatePeriod example
<?php
$start = new DateTime('2012-07-01');
$interval = new DateInterval('P7D');
$end = new DateTime('2012-07-31');
$recurrences = 4;
$iso = 'R4/2012-07-01T00:00:00Z/P7D';
// All of these periods are equivalent.
$period = new DatePeriod($start, $interval, $recurrences);
$period = new DatePeriod($start, $interval, $end);
$period = new DatePeriod($iso);
// By iterating over the DatePeriod object, all of the
// recurring dates within that period are printed.
foreach ($period as $date) {
echo $date->format('Y-m-d')."
";
}
?>
The above example will output:
2012-07-01
2012-07-08
2012-07-15
2012-07-22
2012-07-29
Example #2
DatePeriod example with DatePeriod::EXCLUDE_START_DATE
<?php
$start = new DateTime('2012-07-01');
$interval = new DateInterval('P7D');
$end = new DateTime('2012-07-31');
$period = new DatePeriod($start, $interval, $end,
DatePeriod::EXCLUDE_START_DATE);
// By iterating over the DatePeriod object, all of the
// recurring dates within that period are printed.
// Note that, in this case, 2012-07-01 is not printed.
foreach ($period as $date) {
echo $date->format('Y-m-d')."
";
}
?>
The above example will output:
2012-07-08
