Derived from code by [Fredrik Lindberg](https://github.com/fredriklindberg). Installation ------------ [](#installation) Install with [Composer](https://getcomposer.org/): ``` composer require tankfairies/guid ``` API documentation ----------------- [](#api-documentation) The \[latest class API documentation\]\[apidocs\] is available online. Usage ----- [](#usage) There are four GUID types available. GUID Version: - ``` GuidInterface::UUID_TIME -> Time based UUID (version 1) GuidInterface::UUID_NAME_MD5 -> Name based (MD5) UUID (version 3) GuidInterface::UUID_RANDOM -> Random UUID (version 4) GuidInterface::UUID_NAME_SHA1 -> Name based (SHA1) UUID (version 5) ``` All the GUIDs can be generated in one of three formats String, binary and byte. GUID format: - ``` GuidInterface::FMT_STRING GuidInterface::FMT_BINARY GuidInterface::FMT_BYTE ``` The guid generate function has four parameters: - ``` $guid->generate( version, format, salt, namespace ) ``` The salt needs to be at least 6 characters long. A salt is required for versions 1 but optional for versions 3 and 5. Generate a Version one GUID. (The third parameter is a salt and is required). ``` use Tankfairies\Guid\Guid; $guid = new Guid(); $guidToken = $guid->generate( GuidInterface::UUID_TIME, GuidInterface::FMT_STRING, 'thesalt' ); ``` Generate a Version three GUID. ``` use Tankfairies\Guid\Guid; $guid = new Guid(); $guidToken = $guid->generate( GuidInterface::UUID_NAME_MD5, GuidInterface::FMT_STRING, 'thesalt', 'thenamespace' ); ``` Generate a Version four GUID. ``` use Tankfairies\Guid\Guid; $guid = new Guid(); $guidToken = $guid->generate( GuidInterface::UUID_RANDOM, GuidInterface::FMT_STRING ); ``` Generate a Version five GUID. ``` use Tankfairies\Guid\Guid; $guid = new Guid(); $guidToken = $guid->generate( GuidInterface::UUID_NAME_SHA1, GuidInterface::FMT_STRING ); ``` Copyright and license --------------------- [](#copyright-and-license) The tankfairies/guid library is Copyright (c) 2019 Tankfairies () and licensed for use under the MIT License (MIT). ### Health Score 38 — LowBetter than 85% of packages Maintenance31 Infrequent updates — may be unmaintained Popularity18 Limited adoption so far Community10 Small or concentrated contributor base Maturity78 Established project with proven stability Bus Factor1 Top contributor holds 84.8% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
