ramsey/uuid is a PHP library for generating and working with RFC 4122 version 1, 2, 3, 4, and 5 universally unique identifiers (UUID). ramsey/uuid also supports optional and non-standard features, such as version 6 UUIDs, GUIDs, and other approaches for encoding/decoding UUIDs. A universally unique identifier, or UUID, is a 128-bit unsigned integer, usually represented as a hexadecimal string split into five groups with dashes. The most widely-known and used types of UUIDs are defined by RFC 4122. The probability of duplicating a UUID is close to zero, so they are a great choice for generating unique identifiers in distributed systems. UUIDs can also be stored in binary format, as a string of 16 bytes. The JSON extension is normally enabled by default, but it is possible to disable it. Other required extensions include PCRE and SPL. These standard extensions cannot be disabled without patching PHP’s build system and/or C sources.
