Bit-Wasp/buffertools-php

Toolbox for working with binary and hex data. Similar to NodeJS Buffer.

Buffertools

This library provides a Buffer and Parser class to make dealing with binary data in PHP easier. Templates extend this by offering a read/write interface for larger serialized structures.

Requirements:

• PHP 7.0+
• Composer
• ext-gmp

Installation

You can install this library via Composer: composer require bitwasp/buffertools

Examples

Buffer's are immutable classes to store binary data. Buffer::hex can be used to initialize from hex Buffer::int can be used to initialize from a positive decimal integer (int|string)

Buffer's main methods are:

• getBinary()
• getHex()
• getInt()

Parser will read Buffers. Parser's main methods are:

• readBytes()
• writeBytes()
• readArray()
• writeArray()

In most cases, the interface offered by Parser should not be used directly. Instead, Templates expose read/write access to larger serialized structures.

• Example 1: Using buffer to wrap binary data
• Example 2: Using parser to extract binary data
• Example 3: Using templates to read multiple elements from a parser
• Example 4: Using templates to read/write structured messages
