Day of week library, _(*2)

Usage

Please read the docs of php-enum first., _(*3)

use Hrevert\Day\Day;

/** @var Day */
$day = Day::get(Day::MONDAY);
// or $day = Day::MONDAY();
// or $day = Day::getByName('MONDAY');
// or $day = Day::getByOrdinal(1);  i.e. find by ISO-8601 numeric representation of day

/** @var Day */
$today = Day::getToday();

use Hrevert\Day\Day;
use Hrevert\Day\DayCollection;

$days = new DayCollection([Day::SUNDAY(), Day::MONDAY()]);

var_dump($days->contains(Day::SUNDAY())); // bool(true)
var_dump($days->contains(Day::MONDAY())); // bool(true)

$days->remove(Day::MONDAY());
var_dump($days->contains(Day::MONDAY())); // bool(false)

$days->add(Day::MONDAY());
var_dump($days->contains(Day::MONDAY())); // bool(true)

Since Hrevert\Day\DayCollection is just an extension of Doctrine\Common\Collections\ArrayCollection, it should not be so difficult., _(*4)

Using in <select> element

use Hrevert\Day\Day;

echo '<select name="day">';
foreach (Day::getOptions() as $iso => $display) {
    echo '<option value="' . $iso . '">' . $display . '</option>';
}
echo '</select>';


// on form submit
/** @var Hrevert\Day\Day */
$day = Hrevert\Day\Day::get((int) $_POST['day']);
