ByteBuf extension for PHP

This extension provides a high performance byte buffer implementation for PHP. Replacement for pack(), unpack(), and pmmp/BinaryUtils

⚠️ This extension is still under development. There is a possibility that this extension will crash or behave incorrectly.

Performance

• ByteBuf uses exponential growth for buffer size to prevent frequent memory allocation.
• LE & BE performance is ~2x faster than pack() and unpack()

Comparison with pmmp/BinaryUtils

• ByteBuf->read and ByteBuf->write performance is ~2x faster
• VarInt reading and writing performance is ~9x faster
• Triad reading and writing performance is ~3x faster

Comparison with pmmp/ext-encoding

• ByteBuf->read performance is ~1.5x faster

Documentation

Self-explanatory, see bytebuf.stub.php and tests

TODO

• Reusable ByteBuf to reduce memory allocation
• More tests

How to build?

1. Make sure you have PHP development environment installed and downloaded the PHP Source Code. See: Windows, Linux
2. Clone this repository to /path/to/php-src/ext/bytebuf
3. To build on Windows, you need to run terminal via phpsdk-vs17-x64.bat. Run the following commands:

cd /path/to/php-src

buildconf
./configure --enable-bytebuf (...other options)
make # For Linux
nmake # For Windows
