Simple library to generating RFC 4122 version 3,4 and 5 UUID (Universaly Unique Identifier).

From [Wikipedia](https://en.wikipedia.org/wiki/Universally_unique_identifier):A universally unique identifier (UUID) is a 128-bit number used to identify information in computer systems. Microsoft uses the term globally unique identifier (GUID), either as a synonym for UUID or to refer to a particular UUID variant.

[](#usage)

### Generating UUID v3

[](#generating-uuid-v3)

Include uuid factory in your project

```
use MayMeow\UuidFactory;
```

To generate UUID version 3 from namespace and name:

```
// Version 3 uuid for DNS
$uuidv3 = Uuid::v3(Uuid::NAMESPACE_DNS, 'test.maymeow.click');

// From v2.0
$uuidv3 = UuidFactory::v3(UuidFactory::NAMESPACE_DNS, 'test.maymeow.click');
```

### Generating UUID v4

[](#generating-uuid-v4)

To generate UUID version 3 - random UUID

```
// Version 3 uuid for DNS
$uuidv4 = Uuid::v4();

// From v2.0
$uuidv4 = UuidFactory::v4();
```

### Generating UUID v5

[](#generating-uuid-v5)

To generate UUID version 5 from namespace and name:

```
// Version 5 uuid for DNS
$uuidv3 = Uuid::v5(Uuid::NAMESPACE_DNS, 'test.maymeow.click');

//From version 2.0 use UuidFactory instead of Uuid
$uuidv3 = UuidFactory::v5(UuidFactory::NAMESPACE_DNS, 'test.maymeow.click');
```

### Checking if uuid is valid

[](#checking-if-uuid-is-valid)

```
// Version 3 uuid for DNS
$response = Uuid::is_valid('454eb932-adf4-52a5-9285-31ccebc92e96');

// From v2.0
$response = UuidFactory::is_valid('454eb932-adf4-52a5-9285-31ccebc92e96');
