# 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. [](https://travis-ci.org/Bit-Wasp/buffertools-php) [](https://scrutinizer-ci.com/g/bit-wasp/buffertools-php/?branch=master) [](https://scrutinizer-ci.com/g/Bit-Wasp/buffertools-php/?branch=master) [](https://packagist.org/packages/bitwasp/buffertools) [](https://packagist.org/packages/bitwasp/buffertools) [](https://packagist.org/packages/bitwasp/buffertools) ## 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](./examples/usingBuffer.php) - [Example 2: Using parser to extract binary data](./examples/usingParser.php) - [Example 3: Using templates to read multiple elements from a parser](./examples/usingTemplates.php) - [Example 4: Using templates to read/write structured messages](./examples/usingTemplates2.php)
