Functions

v1()

Returns a version 1 (time-based) UUID from a host ID, sequence number, and the current time

v1([Hexadecimal|int|string|null $node = null ][, int $clockSeq = null ]) : string
Parameters
$node : Hexadecimal|int|string|null = null

A 48-bit number representing the hardware address; this number may be represented as an integer or a hexadecimal string

$clockSeq : int = null

A 14-bit number used to help avoid duplicates that could arise when the clock is set backwards in time or if the node ID changes

Return values
string

Version 1 UUID as a string

v2()

Returns a version 2 (DCE Security) UUID from a local domain, local identifier, host ID, clock sequence, and the current time

v2(int $localDomain[, Integer|null $localIdentifier = null ][, Hexadecimal|null $node = null ][, int|null $clockSeq = null ]) : string
Parameters
$localDomain : int

The local domain to use when generating bytes, according to DCE Security

$localIdentifier : Integer|null = null

The local identifier for the given domain; this may be a UID or GID on POSIX systems, if the local domain is person or group, or it may be a site-defined identifier if the local domain is org

$node : Hexadecimal|null = null

A 48-bit number representing the hardware address

$clockSeq : int|null = null

A 14-bit number used to help avoid duplicates that could arise when the clock is set backwards in time or if the node ID changes

Return values
string
