Network Library for PHP with native Yggdrasil support

## Install

`composer require yggverse/net`

## Usage

### Socket

#### Check socket is open

```
var_dump(
    \Yggverse\Net\Socket::isOpen('yo.index', 80)
);
```

#### Check host valid

```
var_dump(
    \Yggverse\Net\Socket::isHost('yo.index')
);
```

#### Check port valid

```
var_dump(
    \Yggverse\Net\Socket::isPort(80)
);
```

### Dig

#### Resolve records

```
var_dump(
    \Yggverse\Net\Dig::records('yo.index', ['A', 'AAAA'], &$result = [], &$error = [], $provider = null, $timeout = 5)
);
```

#### Check hostname valid

```
var_dump(
    \Yggverse\Net\Dig::isHostName('yo.index')
);
```

#### Check record valid

```
var_dump(
    \Yggverse\Net\Dig::isRecord('A')
);
```

#### Check record value valid

```
var_dump(
    \Yggverse\Net\Dig::isRecordValue('A', '127.0.0.1')
);
```

### Resolve

#### Init resolver

```
$resolve = new \Yggverse\Net\Resolve(
    [
        'A',
        'AAAA'
    ],
    [
        '1.1.1.1',
        '8.8.8.8'
    ],
    // ..
);
```

#### Get resolved URL string

```
$resolved = $resolve->url(
    'https://en.wikipedia.org/wiki/Domain_Name_System'
    // next arguments contain debug variables and new address object
);

if ($resolved)
{
    var_dump(
        $resolved // https://185.15.59.224/wiki/Domain_Name_System
    );
}
```

#### Resolve Address object

```
$resolved = $resolve->address(
    new \Yggverse\Net\Address(
        'https://en.wikipedia.org/wiki/Domain_Name_System'
    )
);

if ($resolved)
{
    var_dump(
        $resolved->get() // https://185.15.59.224/wiki/Domain_Name_System
    );

    var_dump(
        $resolved->getHost() // 185.15.59.224
    );
}
```

### Address

Includes methods to work with network addresses.

#### Base address methods

Different operations with address parts:

* `scheme`
* `user`
* `password`
* `host`
* `protocol`
* `path`
* `query`
* `fragment`

#### Address conversion from relative to absolute format

**Document root**

```
$base = new \Yggverse\Net\Address(
    'http://yo.ygg/a1/b1/c1'
);

$address = new \Yggverse\Net\Address(
    '/a2'
);

var_dump(
    $address->getAbsolute(
        $base
    ) // return http://yo.ygg/a2
);
```

**Current folder**

```
$base = new \Yggverse\Net\Address(
    'http://yo.ygg/a1/b1/c1'
);

$address = new \Yggverse\Net\Address(
    'c2'
);

var_dump(
    $address->getAbsolute(
        $base
    ) // return http://yo.ygg/a1/b1/c2
);
```

**Ending slash**

```
$base = new \Yggverse\Net\Address(
    'http://yo.ygg/a1/b1/c1/'
);

$address = new \Yggverse\Net\Address(
    '../../b2/c2'
);

var_dump(
    $address->getAbsolute(
        $base
    ) // return http://yo.ygg/a1/b2/c2
);
```

**All options**

```
$base = new \Yggverse\Net\Address(
    'http://user:password@yo.ygg/a1/b1/c1?attribute=value#anchor'
);

$address = new \Yggverse\Net\Address(
    '../../a2/b2?attribute2=value2#anchor2'
);

var_dump(
    $address->getAbsolute(
        $base
    ) // return http://user:password@yo.ygg/a2/b2?attribute2=value2#anchor2
);
```
