Question

I am trying to create a calendar which enables a user to book certain times over a period of six weeks.

Is there an easy way in php to do this – at present I am using a number of loops with the following:

$end_of_month=cal_days_in_month(CAL_GREGORIAN, $this_month, $this_year);

this seems clumsy and requires numerous loops to determine changes in month, year etc.

So far I am stumped as to what other method to use as I am sure there is a simple way of doing this.

Answer 1

Use DateTime objects, using the DateTime::add() in combination with DateInterval objects:

header("Content-type: text/plain");

$date = new DateTime("2012-01-01");
$one_day = new DateInterval("P1D");
echo $date->format("Y-m-d") . PHP_EOL;
for ($i = 0; $i < 42; $i++) {
    $date->add($one_day);
    echo $date->format("Y-m-d") . PHP_EOL;
}

This example would output all the dates in a six-week period from the initial date. But it’s very flexible and can do whatever you want it to.
