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.

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.
