-# Socket
+# InitPHP Socket Manager
+
+PHP Socket (TCP, TLS, UDP, SSL) Server/Client Library
+
+## Requirements
+
+- PHP 7.4 or higher
+- PHP Sockets Extension
+
+## Installation
+
+```
+composer require initphp/socket
+```
+
+## Usage
+
+**Supported Types :**
+
+- TCP
+- UDP
+- TLS
+- SSL
+
+### Factory
+
+`\InitPHP\Socket\Socket::class` It allows you to easily create socket server or client.
+
+#### `Socket::server()`
+
+```php 
+public static function server(int $handler = Socket::TCP, string $host = '', int $port = 0, null|string|float $argument = null): \InitPHP\Socket\Interfaces\SocketServerInterface
+```
+
+- `$handler` : `Socket::SSL`, `Socket::TCP`, `Socket::TLS` or `Socket::UDP`
+- `$host` : Identifies the socket host. If not defined or left blank, it will throw an error.
+- `$port` : Identifies the socket port. If not defined or left blank, it will throw an error.
+- `$argument` : This value is the value that will be sent as 3 parameters to the constructor method of the handler.
+    - SSL or TLS = (float) Defines the timeout period.
+    - UDP or TCP = (string) Defines the protocol family to be used by the socket. "v4", "v6" or "unix"
+
+#### `Socket::client()`
+
+```php 
+public static function client(int $handler = self::TCP, string $host = '', int $port = 0, null|string|float $argument = null): \InitPHP\Socket\Interfaces\SocketClientInterface
+```
+
+- `$handler` : `Socket::SSL`, `Socket::TCP`, `Socket::TLS` or `Socket::UDP`
+- `$host` : Identifies the socket host. If not defined or left blank, it will throw an error.
+- `$port` : Identifies the socket port. If not defined or left blank, it will throw an error.
+- `$argument` : This value is the value that will be sent as 3 parameters to the constructor method of the handler.
+    - SSL or TLS = (float) Defines the timeout period.
+    - UDP or TCP = (string) Defines the protocol family to be used by the socket. "v4", "v6" or "unix"
+
+### Methods
+
+**`connection()` :** Initiates the socket connection.
+
+```php 
+public function connection(): self;
+```
+
+**`disconnect()` :** Terminates the connection.
+
+```php 
+public function disconnect(): bool;
+```
+
+**`read()` :** Reads data from socket.
+
+```php 
+public function read(int $length = 1024): ?string;
+```
+
+**`write()` :** Writes data to the socket
+
+```php 
+public function write(string $string): ?int;
+```
+
+#### Server Methods
+
+**`live()` :**
+
+```php 
+public function live(callable $callback): void;
+```
+
+**`wait()` :**
+
+```php 
+public function wait(int $second): void;
+```
+
+#### Special methods for TLS and SSL.
+
+TLS and SSL work similarly.
+
+There are some additional methods you can use from TLS and SSL sockets.
+
+**`timeout()` :** Defines the timeout period of the current.
+
+```php
+public function timeout(int $second): self;
+```
+
+**`blocking()` :** Sets the blocking mode of the current.
+
+```php
+public function blocking(bool $mode = true): self;
+```
+
+**`crypto()` :** Turns encryption on or off on a connected socket.
+
+```php
+public function crypto(?string $method = null): self;
+```
+
+Possible values for `$method` are;
+
+- "sslv2"
+- "sslv3"
+- "sslv23"
+- "any"
+- "tls"
+- "tlsv1.0"
+- "tlsv1.1"
+- "tlsv1.2"
+- NULL
+
+**`option()` :** Defines connection options for SSL and TLS. see; [https://www.php.net/manual/en/context.ssl.php](https://www.php.net/manual/en/context.ssl.php)
+
+```php
+public function option(string $key, mixed $value): self;
+```
+
+### Socket Server
+
+_**Example :**_
+
+```php
+require_once "../vendor/autoload.php";
+use \InitPHP\Socket\Socket;
+use \InitPHP\Socket\Interfaces\SocketServerInterface;
+
+$server = Socket::server(Socket::TLS, '127.0.0.1', 8080);
+$server->connection();
+
+$server->live(function (SocketServerInterface $socket) {
+    switch ($socket->read()) {
+        case 'exit' : 
+            $socket->write('Goodbye!');
+            return;
+        case 'write' :
+            $socket->write('Run write command.');
+        break;
+        case 'read' :
+            $socket->write('Run read command.');
+        break;
+        default: return;
+    }
+});
+```
+
+### Socket Client
+
+_**Example :**_
+
+```php
+require_once "../vendor/autoload.php";
+use \InitPHP\Socket\Socket;
+
+$client = Socket::client(Socket::SSL, 'smtp.gmail.com', 465);
+
+$client->option('verify_peer', false)
+    ->option('verify_peer_name', false);
+
+$client->connection();
+
+$client->write('EHLO [127.0.0.1]');
+
+echo $client->read();
+```
+
+_In the above example, a simple smtp connection to gmail is made._
