PHP Library for reading and writing binary data

I intentionally needed that for writing a PHP Client for TrafficCop. But the source grows so I decided to move it into an own package. You can also call this a pack() wrapper.

Install

Installation should be done via composer.

{
    "require": {
        "TrafficCophp/ByteBuffer": "dev-master"
    }
}

Example

A simple usage example could look like this

<?php

require __DIR__ . '/vendor/.composer/autoload.php';

use TrafficCophp\ByteBuffer\ByteBuffer;

$channel = 'channel_one';
$message = 'php';

$buffer = new ByteBuffer(4 + 1 + 4 + strlen($channel) + strlen($message));
$buffer->writeInt32BE($buffer->length(), 0);
$buffer->writeInt8(0x1, 4);
$buffer->writeInt32BE(strlen($channel), 5);
$buffer->write($channel, 9);
$buffer->write($message, 9 + strlen($channel));

$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
$result = socket_connect($socket, '127.0.0.1', 3542);

socket_write($socket, (string) $buffer, $buffer->length());

ToDo's

• Write Documentation
• Improve examples
• Allow Buffer as constructor
• Write test for concatinating buffers
