A Doctrine integration of janklan/simple-date-time.

Why?

Databases Doctrine integrates with support DATE and TIME data types, but Doctrine converts those values to a PHP's native \DateTimeImmutable objects, forcing additional complexity onto you when you don't want it: time zones, and a date when you only want to work with time and vice versa.

For example:

• Birthdays: A birthday is January 15th, not "January 15th in UTC-5"
• Special Days: The Australia Day is on January 26th, The Independence Day is on July 4th - regardless of which time zone in Australia or the U.S. you are
• Business hours: Standard business hours across a global enterprise could be 9am to 5pm, regardless of where on Earth do you work for the business: you have to rock up at 9am for work, wherever you are.

janklan/simple-date-time provides a solution at a PHP level, and this package provides the connecting dots between that solution and Doctrine.

Installation

composer require janklan/simple-date-time-for-doctrine

Configuration

This package provides four Doctrine DBAL types:

Doctrine (standalone)

Register the types before using them:

use Doctrine\DBAL\Types\Type;
use JanKlan\SimpleDateTimeForDoctrine\SimpleDateImmutableType;
use JanKlan\SimpleDateTimeForDoctrine\SimpleTimeImmutableType;

Type::addType('simple_date_immutable', SimpleDateImmutableType::class);
Type::addType('simple_time_immutable', SimpleTimeImmutableType::class);

Symfony

Add to config/packages/doctrine.yaml:

doctrine:
    dbal:
        types:
            simple_date_immutable: JanKlan\SimpleDateTimeForDoctrine\SimpleDateImmutableType
            simple_date: JanKlan\SimpleDateTimeForDoctrine\SimpleDateType
            simple_time_immutable: JanKlan\SimpleDateTimeForDoctrine\SimpleTimeImmutableType
            simple_time: JanKlan\SimpleDateTimeForDoctrine\SimpleTimeType

Usage

Once configured, use the types in your entity mappings:

use Doctrine\ORM\Mapping as ORM;
use JanKlan\SimpleDateTime\SimpleDate;
use JanKlan\SimpleDateTime\SimpleDateImmutable;
use JanKlan\SimpleDateTime\SimpleTime;
use JanKlan\SimpleDateTime\SimpleTimeImmutable;

#[ORM\Entity]
class Employee
{
    #[ORM\Column(type: 'simple_date_immutable')]
    public SimpleDateImmutable $immutableBirthday;

    #[ORM\Column(type: 'simple_time_immutable')]
    public SimpleTimeImmutable $immutableShiftStart;

    #[ORM\Column(type: 'simple_date')]
    public SimpleDate $mutableBirthday;

    #[ORM\Column(type: 'simple_time')]
    public SimpleTime $mutableShiftStart;
}

A warning about object comparison

PHP will let you compare the Simple(Date|Time)(Immutable|) classes with native \DateTimeInterface objects, but doing so is risky and discouraged. All classes offer a custom isSame, isBefore and isAfter methods that should be used for comparison - they will ignore the time zone in the object you're comparing the other side with.

janklan/simple-date-time provides a PHPStan rule that you should add to your PHPStan configuration to get warnings about unsafe comparisons.

Contributing

PR are welcome. All you need to do to get started is to check out the repository, run composer install and you're done.

Several shorthand commands are configured in Composer: cs, phpstan, rector, test, and preflight. See composer.json to find out what they do.

Run composer preflight at least at the end of your work, before you create a pull request.

Testing

The test suite is split into two categories: Unit and Functional tests.

Running all tests

By default, PHPUnit runs both unit and functional tests:

./vendor/bin/paratest

Note: Functional tests require database containers to be running (see below).

Unit Tests

Unit tests verify type conversion logic without requiring a database connection:

composer test:unit

Functional Tests

Functional tests verify actual database round-trips (PHP -> DB -> PHP) against real PostgreSQL and MySQL databases.

Starting the databases

Start the Docker containers before running functional tests:

docker compose up -d

This starts:

• PostgreSQL on port 15432 (default version: 18)
• MySQL on port 13306 (default version: 9)

Running functional tests

Run all functional tests:

composer test:functional

Run only PostgreSQL tests:

composer test:functional -- --group postgres

Run only MySQL tests:

composer test:functional -- --group mysql

Stopping the databases

docker compose down
