# PHP Library for reading and writing binary data
|
|
|
|
[](http://travis-ci.org/nesQuick/ByteBuffer) [](http://unmaintained.tech/)
|
|
|
|
I intentionally needed that for writing a PHP Client for [TrafficCop](https://github.com/santosh79/traffic_cop/).
|
|
But the source grows so I decided to move it into an own package.
|
|
You can also call this a [pack()](http://www.php.net/manual/en/function.pack.php) wrapper.
|
|
|
|
## Install
|
|
|
|
Installation should be done via [composer](http://packagist.org/).
|
|
|
|
```
|
|
{
|
|
"require": {
|
|
"TrafficCophp/ByteBuffer": "dev-master"
|
|
}
|
|
}
|
|
```
|
|
|
|
## Example
|
|
|
|
A simple usage example could look like this
|
|
|
|
```php
|
|
<?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
