PHP Socket (TCP, TLS, UDP, SSL) Server/Client Library
- PHP 7.4 or higher
- PHP Sockets Extension
composer require initphp/socket Supported Types :
- TCP
- UDP
- TLS
- SSL
\InitPHP\Socket\Socket::class It allows you to easily create socket server or client.
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::TLSorSocket::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"
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::TLSorSocket::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"
connection() : Initiates the socket connection.
public function connection(): self;disconnect() : Terminates the connection.
public function disconnect(): bool;read() : Reads data from socket.
public function read(int $length = 1024): ?string;write() : Writes data to the socket
public function write(string $string): ?int;live() :
public function live(callable $callback): void;wait() :
public function wait(int $second): void;broadcast() :
public function broadcast(string $message, array|string|int|null $clients = null): bool;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.
public function timeout(int $second): self;blocking() : Sets the blocking mode of the current.
public function blocking(bool $mode = true): self;crypto() : Turns encryption on or off on a connected socket.
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
public function option(string $key, mixed $value): self;Example :
require_once "../vendor/autoload.php"; use \InitPHP\Socket\Socket; use \InitPHP\Socket\Interfaces\{SocketServerInterface, SocketServerClientInterface}; $server = Socket::server(Socket::TLS, '127.0.0.1', 8080); $server->connection(); $server->live(function (SocketServerInterface $socket, SocketServerClientInterface $client) { $read = $client->read(); if (!$read) { return; } if (in_array($read, ['exit', 'quit'])) { $client->push("Goodbye!"); $client->close(); return; } else if (preg_match('/^REGISTER\s+([\w]{3,})$/i', $read, $matches)) { // REGISTER admin $name = trim(mb_substr($read, 9)); $socket->clientRegister($name, $client); } else if (preg_match('/^SEND\s@([\w]+)\s(.*)$/i', $read, $matches)) { // SEND @admin Hello World $pushSocketName = $matches[1]; $message = $matches[2]; $socket->broadcast($message, [$pushSocketName]) } else { $message = trim($read); !empty($message) && $socket->broadcast($message); } });Example :
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.
