Requirements
|
|
############
|
|
|
|
ramsey/uuid |version| requires the following:
|
|
|
|
* PHP 7.2+
|
|
* `ext-json <https://www.php.net/manual/en/book.json.php>`_
|
|
|
|
The JSON extension is normally enabled by default, but it is possible to disable
|
|
it. Other required extensions include
|
|
`PCRE <https://www.php.net/manual/en/book.pcre.php>`_
|
|
and `SPL <https://www.php.net/manual/en/book.spl.php>`_. These standard
|
|
extensions cannot be disabled without patching PHP's build system and/or C
|
|
sources.
|
|
|
|
ramsey/uuid recommends installing/enabling the following extensions. While not
|
|
required, these extensions improve the performance of ramsey/uuid.
|
|
|
|
* `ext-ctype <https://www.php.net/manual/en/book.ctype.php>`_
|
|
* `ext-gmp <https://www.php.net/manual/en/book.gmp.php>`_
|
|
* `ext-bcmath <https://www.php.net/manual/en/book.bc.php>`_
|

|
Install With Composer
|
|
#####################
|
|
|
|
The only supported installation method for ramsey/uuid is
|
|
`Composer <https://getcomposer.org>`_. Use the following command to add
|
|
ramsey/uuid to your project dependencies:
|
|
|
|
.. code-block:: bash
|
|
|
|
composer require ramsey/uuid
|
|
|
|
|
|
Using ramsey/uuid
|
|
#################
|
|
|
|
After installing ramsey/uuid, the quickest way to get up-and-running is to use
|
|
the static generation methods.
|
|
|
|
.. code-block:: php
|
|
|
|
use Ramsey\Uuid\Uuid;
|
|
|
|
$uuid = Uuid::uuid4();
|
|
|
|
printf(
|
|
"UUID: %s\nVersion: %d\n",
|
|
$uuid->toString(),
|
|
$uuid->getFields()->getVersion()
|
|
);
|
|
|
|
This will return an instance of ``Ramsey\Uuid\Rfc4122\UuidV4``.
|
|
|
|
.. tip::
|
|
.. rubric:: Use the Interfaces
|
|
|
|
Feel free to use ``instanceof`` to check the specific instance types of
|
|
UUIDs. However, when using type hints, it's best to use the interfaces.
|
|
|
|
The most lenient interface is ``Ramsey\Uuid\UuidInterface``, while
|
|
``Ramsey\Uuid\Rfc4122\UuidInterface`` ensures the UUIDs you're using conform
|
|
to the `RFC 4122`_ standard. If you're not sure which one to use, start with
|
|
the stricter ``Ramsey\Uuid\Rfc4122\UuidInterface``.
|
|
|
|
ramsey/uuid provides a number of helpful static methods that help you work with
|
|
and generate most types of UUIDs, without any special customization of the
|
|
library.
