### Installation

```bash
composer require andkom/php-bitcoin-address
```

### Examples

Generate a P2PK/P2PKH address:

```php
$address = OutputFactory::p2pk($pubKey)->address();
$address = OutputFactory::p2pkh($pubKeyHash)->address();
```

Generate a P2MS address:

```php
$address = OutputFactory::p2ms(2, [$pubKey1, $pubKey2, $pubKey3])->address();
```

Generate a P2SH address:

```php
$factory = new OutputFactory();
$p2ms = $factory->p2ms(2, [$pubKey1, $pubKey2, $pubKey3]);
$address = $factory->p2sh($p2ms)->address();
```

Generate a P2WPKH address:

```php
$address = OutputFactory::p2wpkh($pubKeyHash)->address();
```

Generate a P2WSH address:

```php
$factory = new OutputFactory();
$p2ms = $factory->p2ms(2, [$pubKey1, $pubKey2, $pubKey3]);
$address = $factory->p2wsh($p2ms)->address();
```

Generate a P2WPKH-over-P2SH address:

```php
$factory = new OutputFactory();
$p2wpkh = $factory->p2wpkh($pubKeyHash);
$address = $factory->p2sh($p2wpkh)->address();
```

Generate a P2WSH-over-P2SH address:

```php
$factory = new OutputFactory();
$p2ms = $factory->p2ms(2, [$pubKey1, $pubKey2, $pubKey3]);
$p2wsh = $factory->p2wsh($p2ms);
$address = $factory->p2sh($p2wsh)->address();
```

Generate a P2TR address:

```php
$taprootPubKey = Taproot::construct($pubKey);
$address = OutputFactory::p2tr($taprootPubKey)->address();
```

Generate an address from an output script:

```php
$address = OutputFactory::fromScript($script)->address();
```

Decode a Bitcoin address:

```php
$output = NetworkFactory::bitcoin()->decodeAddress('1BgGZ9tcN4rm9KBzDn7KprQz87SZ26SAMH');
```

Get a Bitcoin address type:

```php
$type = NetworkFactory::bitcoin()->decodeAddress('1BgGZ9tcN4rm9KBzDn7KprQz87SZ26SAMH')->type(); // p2pkh
```

Validate a Bitcoin address:

```php
NetworkFactory::bitcoin()->validateAddress('1BgGZ9tcN4rm9KBzDn7KprQz87SZ26SAMH'); // true
```
