README

Pure PHP calendar library. Zero dependencies. Built for server-side rendering.

Feed it a date. Get back a typed Day[][] table. Build your own template.

Why server-side?

• Works with Symfony UX Turbo / Livewire — no hydration, no client state sync
• Zero frontend dependencies — just your own HTML and CSS
• Every cell carries arbitrary data attached via a simple interface
• Fully immutable — every mutation returns a new instance

Installation

composer require tito10047/php-calendar

Requires PHP 8.2+. No other dependencies.

Quick start

use Tito10047\Calendar\Calendar;
use Tito10047\Calendar\Enum\CalendarType;
use Tito10047\Calendar\Enum\DayName;

$calendar = Calendar::forMonth(2024, 11)
    ->disableDaysByName(DayName::Saturday, DayName::Sunday)
    ->setDataLoader(new MyEventLoader());

$table = $calendar->getDaysTable();
// array<int weekNumber, array<int isoDay 1–7, Day>>

<table class="calendar">
    <tbody>
        {% for week in table %}
            <tr>
                {% for day in week %}
                    <td class="{{ day.ghost ? 'ghost' : '' }} {{ day.today ? 'today' : '' }} {{ day.enabled ? '' : 'disabled' }}">
                        {% if not day.ghost %}
                            <span>{{ day.date|date('j') }}</span>
                            {% for event in day.data ?? [] %}
                                <div class="event">{{ event.title }}</div>
                            {% endfor %}
                        {% endif %}
                    </td>
                {% endfor %}
            </tr>
        {% endfor %}
    </tbody>
</table>

The Day object

Every cell is a readonly value object:

$day->date      // DateTimeImmutable
$day->ghost     // belongs to adjacent month (grid padding, Monthly only)
$day->today     // matches today's date
$day->enabled   // not disabled by any rule
$day->data      // ?array — whatever your DayDataLoaderInterface returned

Calendar types

Calendar::forMonth(2024, 11)                         // full month, aligned to complete weeks
Calendar::forWeek(new DateTimeImmutable('2024-11-04')) // one week, Mon–Sun
Calendar::forToday(CalendarType::WorkWeek)           // this week, Mon–Fri

Or with navigation:

$next = $calendar->nextPeriod(); // next month / next week — depends on type
$prev = $calendar->prevPeriod();

Disable and enable days

Three independent layers — see docs/disable-model.md for the full model.

$calendar = Calendar::forMonth(2024, 11)
    ->disableDaysByName(DayName::Saturday, DayName::Sunday)  // structural — survives navigation
    ->disableDays(new DateTimeImmutable('2024-11-11'))        // date-specific — resets on navigation
    ->enableDays(new DateTimeImmutable('2024-11-30'));        // exception — override for one date
