By participating in this project and its community, you are expected to uphold this code. ![]() Otherwise you can require lib/Uuid.php directly. If you are using composer, make sure you require 'vendor/autoload.php, then the code should Just Work. This project adheres to a Contributor Code of Conduct. Generate RFC-4122 compliant random UUIDs with better statistical dispersion than mtrand(), and 5x faster than createuuid(). Except explicit open source licence (indicated Creative Commons / free), the "UUID" algorithm, the applet or snippet (converter, solver, encryption / decryption, encoding / decoding, ciphering / deciphering, breaker, translator), or the "UUID" functions (calculate, convert, solve, decrypt / encrypt, decipher / cipher, decode / encode, translate) written in any informatic language (Python, Java, PHP, C#, Javascript, Matlab, etc.) and all data download, script, or API access for "UUID" are not public, same for offline use on PC, mobile, tablet, iPhone or Android app! ramsey/uuid is a PHP 5.4+ library for generating and working with RFC 4122 version 1, 3, 4, and 5 universally unique identifiers (UUID). Version 5 uses SHA-1 instead of MD5.The UUID code contains 128 bits presented in the form of 32 hexadecimal characters divided into 8-4-4-4-12 digits (base 16) and separated by a dash - Ask a new question Source codeÄCode retains ownership of the "UUID" source code. The only difference between version 3 and version 5 is that a different hashing algorithm is used. The exact number of possibilities is about ²¹²â¸. Thereâs still a chance that a UUID could be duplicated but itâs tiny because of the high number of possible combinations. Every bit of the string is totally ârandomlyâ generated. This version uses a pseudo-random number generator to generate the UUID. The MD5 hashing algorithm is a widely used hash function that produces a 128-bit hash value. What is UUID (or GUID) UUID (or GUID) is an acronym for 'Universally Unique Identifier' (or 'Globally Unique Identifier'). We can now use a name and a namespace to create a series of UUIDâs. Webtools - Online UUID (GUID) Generator is a free online tool that helps you generate different versions of UUIDs for software components, database key, or just for anything where unique identifiers are required. No, its not possible to have PHP generate the exact same UUID () as MySQL because its a (completely) random number. ![]() In version 3, cryptographic hashing and application-provided text strings are used to generate a UUID.

GitHub - ramsey/uuid: A PHP library for generating universally unique identifiers (UUIDs). Version 1 UUID is a universally unique identifier thatâs generated using the MAC address of the computer and the time of generation. Versions Version 1 (date-time and MAC address) UUID generation class is taken from the /webpatser/laravel-uuid repo. Generating a universally unique id UUID can be tricky in PHP as the built-in function uniqid() doesnât guarantee the uniqueness of the output id.
