UUID helper

Usage

The UUID class contains methods used to validate and generate UUIDs.

Usage

The validate method checks if a string is a valid UUID. It will return TRUE if is does and FALSE if not.

$valid = UUID::validate('f47ac10b-58cc-4372-a567-0e02b2c3d479'); // TRUE

$valid = UUID::validate('x47ac10b-58cc-4372-a567-0e02b2c3d479'); // FALSE

The v3 method will generate and return a version 3 UUID.

// The namespace must be a valid UUID

$uuid = UUID::v3('f47ac10b-58cc-4372-a567-0e02b2c3d479', 'foobar');

// You can also use one of the predefined namespaces (DNS, URL, OID and X500)

$uuid = UUID::v3(UUID::OID, 'foobar');

The v4 method will return a version 4 UUID.

$uuid = UUID::v4();

Having the the openssl extention installed will improve the randomness of the generated version 4 UUIDs.

The v5 method will return a version 5 UUID.

// The namespace must be a valid UUID

$uuid = UUID::v5('f47ac10b-58cc-4372-a567-0e02b2c3d479', 'foobar');

// You can also use one of the predefined namespaces (DNS, URL, OID and X500)

$uuid = UUID::v5(UUID::OID, 'foobar');
